That enables users to revisit the same view in time and +space later on or share the direct link with someone, overruling the default +client setup. Please note that certain characters are automatically URL encoded, +as URLs sent over the Internet only use the ASCII character set. This means that +if user manually enters for example **:** sign, while entering the website, +it will automatically transform into **%3A**, making the URL less readable. + +* Pre-set the map position by setting **x**, **y** as coordinates of the center + of the map and the zoom with the **z** parameter. `Map position example + `_. +* The time selection is set by `timestart` and `timeend`, and should be entered + as ISO 8601 UTC time format without milliseconds. `Time selection example + `_. +* In case only one main layer is configured (like in the Emergency collection), + additionally custom filters can be saved via their name.

Downloading

+

The download interface is implemented following the Web Coverage Service (WCS) as well as the Download Service for Earth +Observation Products Best Practice (DSEO) standards.

+

These interfaces support both, the simple download of entire products via DSEO +as well as flexible customized downloads via WCS. Both services can be accessed +at the path /ows?.

+

The WCS offers the following customizations in order to optimize downloads and +minimize unnecessarily used bandwidth:

+
    +

  • Earth Observation Application Profile (EO-WCS)

    • +

  • Meaningful default configuration

    • +

  • Spatial subset to retrieve only the geographic area of interest

    • +

  • Range subset to retrieve only the band(s) of interest

    • +

  • Scaling to required resolution

    • +

  • Format selection

    • +

  • Interpolation selection if needed

    • +

  • Projection selection

    • +
+

Note that the download size in WCS is restricted in order to not block the +service. Clients are advised to download bigger coverages in chunks and put them +together afterwards.

+
+

Downloading in QGIS

+

In order to use the download via WCS 1.0, that QGIS supports, a WCS layer needs to be added.

+

Open the Data Source Manager and add a WCS Layer, configuring the URL as shown in Figure 46 and create a new WCS Connection using the URL of the service and specifying the product id to be downloaded via CQL= query. It is necessary to tick the Ignore GetCoverage URI reported in capabilities, as the reference URI usually does not contain the additional CQL or any other request parameters.

+
+QGIS - Create WCS Connection +

Figure 46 QGIS - Create WCS Connection

+
+

A user can be prompted to specify the transformation between coordinate reference systems in case that the default output image is in a different coordinate reference system than current map projection - as shown in Figure 47

+
+QGIS - CRS transformation confirmation +

Figure 47 QGIS - CRS transformation confirmation

+
+

Currently, QGIS supports specifying the output coordinate reference system and image format through the relevant input fields as shown in Figure 48. All other optional parameters for WCS request need to be added to the URL manually clicking on Edit button.

The final chapter Sample Service Requests holds a list of sample requests against +the various services described in this user guide.

Searching

+

The main interface for searching is provided by OpenSearch using various extensions including the Geo and Time +Extensions, the +Extension for Earth Observation as well as the +CEOS OpenSearch Best Practice Document.

+

The OpenSearch URL endpoints are:

+
    +

  • /opensearch: Main service description

    • +

  • /opensearch/<format>: Search for collections in a specific format

    • +

  • /opensearch/collections/<collection-id>: Collection specific description

    • +

  • /opensearch/collections/<collection-id>/<format>: Search for products in +a collection in that format

    • +
+
+

Responses

+

The description related endpoints provide an OpenSearch Description Document +(OSDD). This XML based file format describes general service metadata and +various access URL templates.

+

These URL objects provide templates that can be filled with parameters to submit +actual metadata queries. Depending on the used URL, the search result is +returned in one of the following formats:

+
    +

  • atom: Atom syndication format

    • +

  • rss: RSS

    • +

  • html: HTML

    • +

  • kml: Keyhole Markup Language

    • +

  • json: GeoJSON

    • +
+

The resulting items in that result document can be paged. Specific pages can be +retrieved using the offset and count parameters. Additionally, the +response contains links to the first, last, next, and previous pages of the +result set.

+

The results of the search depend on the type of object being searched. For the +collection search, the result items are collection descriptions of all matched +collections encoded in the selected format. Each description contains a link to +its own specific OSDD document.

+

In product searches, the result document items are descriptions of products, +containing links to thumbnails, browses, and product specific services such as +WMS or WCS. Additionally it contains the products acquisition footprint and +time stamp.

+
+
+

Filters

+

The URL templates for both the collection and the record search allow to pass +parameters that control the query and shape of the search. The following table +shows all parameters available for both collection and product searches:

+ ++++ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Parameter

Description

startIndex

The index offset of the items. Used to get subsets of a result +set

count

The number of records for each page

start

The start time stamp for the time range

end

The end time stamp for the time range

timerel

The semantic of the time range. Either intersects, +contains, disjoint, or equals

bbox

The geographic bounding box expressed as min-lon, +min-lat, max-lon, max-lat in WGS84 coordinates

geom

Viewing

+

The viewing interface is implemented following the Web Map Tile Service (WMTS) as well as the Web Map Service (WMS) standards. Both services are implemented +by a wide range of client software which makes it as simple as possible to +integrate the viewing service as needed.

+

Service endpoints optimized for performance as well as for flexibility are +provided alongside each other. Concrete example URLs demonstrating the +capabilities of the various endpoints are provided in the chapter +Sample Service Requests.

+
+

Performance optimized service

+

The performance optimized service variant is provided under the path +/cache/ows?.

+

This endpoint offers access to predefined visualizations via WMTS and WMS. The +GetTile as well as GetMap requests are answered from image tiles cached on +object storage when possible. Figure 28 below shows the three +predefined visualizations, true color, false color, and NDVI of the same image +tile and Figure 29 the unmasked and masked versions using the +validity mask of one tile.

+
+WMTS Tiles - True color, false color, and NDVI +

Figure 28 WMTS Tiles - True color, false color, and NDVI

+
+
+WMTS Tiles - Unmasked and masked +

Figure 29 WMTS Tiles - Unmasked and masked

+
+

The operator might configure additional layers besides the default ones. These +layers can offer a specific customization described below as performance +optimized variant.

+

For example for the VHR Image 2018 dataset not only the three default layers for +True Color, False Color, and NDVI are configured but also the Masked Validity +one as shown in the figures above.

+

In addition the VHR Image 2018 dataset contains level 1 and 3 products. Thus +individual layers aggregating each level individually are added making the total +of offered layers twelve.

+

Finally two layers are configured offering a quick true color visualization of +the entire level 3 datasets without support of the time dimension both unmasked +as well as masked. The masked layer is shown in +Figure 30 below.

+
+Web Client - Full coverage layer +

Figure 30 Web Client - Full coverage layer

+
+

Image tiles not yet present in the cache are stored upon first hit for +consecutive requests. This is the so-called on-demand caching. The operator +might decide for optimal performance, even for the first request, to pre-seed +the cache. Also a mixed variant with a partly pre-seeded cache for example up to +a certain zoom level is possible.

+

However, this is done fully transparent to the users and the only impact is that +they might need to wait slightly longer when they are the first to visualize a +certain product.

+

This service offers access on collection level only. Individual products can be +addressed using the time parameter given that they do not cover one another +on the time axis.

+

The best performance is offered at the WMTS interface which serves images tiles +as they are cached without the need of any reprocessing. WMS responses are +generated on-the-fly from image tiles and might thus need some reprocessing to +stitch together and scale image tiles.

+

More sophisticated reprocessing like reprojection or custom color adjustments +are not offered at this endpoint.

+
+
+

Flexible service

+

The other service variant offered is optimized for the best possible flexibility +and can be accessed at the path /ows?.

+

This endpoint offers the following customizations via WMS:

+
    +

  • Access to individual products via ID (cql=identifier='ID')

    • +

  • Access to entire collections/datasets supporting time parameter

    • +

  • Various layers as defined by the Earth Observation Application Profile of WMS +(EO-WMS) like +one showing outlines of products (__outlines)

    • +

  • Additional useful layers like one showing both, products and outlines, +correctly rendering topology of outlines (__outlined) or one showing a +validity mask (__validity) or applied validity mask +(___masked_validity)

    • +

  • Numerous styles for layer where feasible like outlines or NDVI +(layers=ID__NDVI&STYLES=coolwarm)

    • +

  • Reprojection to operator configured coordinate reference systems

    • +

  • Color adjustment via custom linear stretch dim_range=<low-red-or-grey> +<high-red-or-grey>[,<low-green> <high-green>,<low-blue> <high-blue>]

    • +

  • Filtering of products to render into collection/dataset visualizations via +Common Query Language (CQL) for example &cql=cloudCover<1

    • +

  • All other standard WMS parameters like transparent, format, etc.

    • +
+

All these customization parameters can of course be combined as needed.

+

Please see the chapter Sample Service Requests for detailed examples of all +supported parameters.

+
+
+

Loading in QGIS

+

Any of the above described layers can be loaded in client software supporting +either the WMTS or WMS standard like for example QGIS.

+

Open the Data Source Manager as shown in Figure 31 and create a +new WMS/WMTS Connection using the URL to the layer of interest.

+

When using parameters like for example cql=identifier='ID' to view one +individual product make sure to tick the “Ignore GetMap/GetTile URI reported in +capabilities” as these parameters are overwritten otherwise.

+
+QGIS - Create WMS/WMTS Connection +

Figure 31 QGIS - Create WMS/WMTS Connection

+
+

The next step is to retrieve the capabilities of the created WMS/WMTS Connection +using the Connect button. Selected layers from the list are added using the Add +button as shown in Figure 32.

+
+WMS loading in QGIS +

Figure 32 WMS loading in QGIS

+
+

An important parameter to consider while viewing the layers is the requested +time interval, allowing for example to observe changes over years. One option is +to manually add a custom time= parameter to the URL after checking the +Ignore GetMap URI checkbox.

+

For QGIS versions lower than 3.14, the only way how to use WMS layers with time +support (WMS-T) is through a maintained plugin called TimeManager. It offers a convenient way to +navigate through the time for raster and vector layers with custom defined steps +as shown in Figure 33.

+
+WMS loading in QGIS with TimeManager +

Figure 33 WMS loading in QGIS with TimeManager

+
+

The plugin needs to be installed first and then set up with the desired layer. +The raster layer to be added to the TimeManager must be first added to the +workspace as shown in Loading in QGIS. By clicking the Settings button and +following up with the Add raster button as can be seen in +Figure 34 it can be then chosen from the list of layers. It is +also suggested to add Start and End time constrains to narrow down the interval +which TimeManager will consider.

+
+Setup of TimeManager +

Figure 34 Setup of TimeManager

+
+

After setting the layer up, it is possible to change the time interval length +(for example one month) and view all products in that interval. After clicking +the play button, it displays the layer iteratively from the defined Start time +to the defined End time, always displaying each frame for a set number of +milliseconds.

+

It even allows exporting an animation as shown in Figure 35 below.

+
+GIF animation from TimeManager +

Figure 35 GIF animation created from TimeManager

+
+

New support for time aware layers was added in QGIS Version 3.14 called +Temporal Controller. This video directly from the author of the +feature shows the usage. However, due to the way that Capabilities of layers are +provided by both View Server components Cache and Renderer, the QGIS Temporal +Controller can not parse the time dimension metadata correctly.

+

For performance reasons the View Server lists only start and end of the time +interval, in which the collection contains some products. It would not be +suitable to list all individual time entries, as there can be easily hundreds of +thousands of them. Both QGIS 3.14 and ArcMap 10.4 expect individual time entries +listing and then determine its own time related behavior while handling these +layers. QGIS 3.14 does not recognize capabilities time interval as time aware +layer and does not add the TIME= parameter to the WMS/WMTS query, so the +TimeManager plugin still stays an ideal choice for QGIS users to view the layers +provided by the View Server.

+
+
+

Loading in ArcMap 10

+

Any of the above described layers can be loaded in ArcMap 10, but the inbuilt +time support does have the same issues as in the case of QGIS 3.14 Time +Controller. Therefore a custom TIME parameter has to be added manually in the +Layer settings.

+

To add a WMS/WMTS layer, click on the Add Layer symbol. Select the Add GIS +Server option and follow up with either Add WMS Server or Add WMTS Server, +as can be seen on Figure 36, Figure 37, and +Figure 38.

+
+

+
+

Then user is required to insert the service URL and click Get Layers. If the +service is secured with some sort of authentication, the user must provide a +valid username and password on the login attempt. After they are supplied, +the list of available layers appears, as seen on Figure 39, and +Figure 40.

+
+ArcMap add WMS Server panel +

Figure 39 ArcMap add WMS Server panel

+
+
+ArcMap add WMS Server panel +

Figure 40 ArcMap add WMS Server panel

+
+

This layer then gets added into the list of layers to choose from for adding +into the workspace, as seen on Figure 41. A user than follows +into the nested structure of sublayers to select the one to explore, as seen on +Figure 42, Figure 43, and +Figure 44.

+
+

In order to limit the displayed time interval, a user needs to add the TIME +parameter to the requests by accessing Layer Properties, expand the Tab +Parameters and enter the time interval as can be seen on +Figure 45. If the TIME parameter was already added in the +previous step of adding a WMS Server, it can not be added for the request twice +and needs to be changed for the whole Data Source.

Web Client

+

The most comfortable way to exploit the functionalities of the View Server (VS) +is via the built-in web client. This client +is based on the open source eoxc library and +provides an intuitively to use interactive graphical user interface running in +the user’s web browser.

+
+

Interactive Tutorial

+

When the web client is opened for the first time a short interactive tutorial +starts as shown in Figure 2 below. It guides the user +through the main features and elements.

+
+Web Client Tutorial - Start +

Figure 2 Web Client Tutorial - Start

+
+

The tutorial can be started again +anytime by clicking the book icon in the bottom right of the window.

+
+Web Client Tutorial Button +

+
+
+
+

Map

+

The main map view is for visualization and interactively browsing through +available satellite data. Navigating to the area of interest is done by:

+
    +

  • panning: left click + drag or one finger drag and

    • +

  • zooming: mouse wheel scroll, double click, two finger pinch, or the plus +and minus icons in the bottom right corner of the map.

    • +
+
+Web Client Tutorial - Map +

Figure 4 Web Client Tutorial - Map

+
+

While hovering over footprints on the map, the respective product(s) are +highlighted in the map, timeslider, and the Search Results menu. The same +behavior is applied vice versa while hovering over dot groups in the +timeslider and individual items in the Search Results.

+
+Web Client - 3-way highlighting +

Figure 5 Web Client - 3-way highlighting

+
+

Clicking on a footprint in the map followed by clicking on the plus or minus +button can be used to add or remove a product to or from the basket, holding +the list of products selected for download (see Download +below).

+
+Web Client - Select on map +

Figure 6 Web Client - Select on map

+
+

In the top most part of the map, there is a colored bar spanning the full width +of the web client acting as loading indicator. It makes it easier to see if the +loading of all requested map tiles is already finished or still in progress.

+
+Web Client - Loading indicator +

The geographic coordinates of the current cursor location can be seen as +longitude, latitude pair in the bottom left corner of the map.

+
+Web Client - Coordinates +

Figure 8 Web Client - Coordinates

+
+

Clicking on the landscape map icon in the bottom right of the map window shows +a list of available layers. Clicking on one of the layers opens a new browser +tab showing this layer as currently visible on the map by generating a WMS +request copying the current map parameters (zoom, bounding box, selected time, +styling, etc.).

+
+Web Client - Current view +

Figure 9 Web Client - Current view

+
+
+
+

Timeslider

+

The timeslider presents the distribution of products in time via a bar (see +Figure 10) or an aggregated dots (see +Figure 11) graph. The visualization mode used +(bars or dots) is based on the total number of products available for the +shown time interval.

+
+Web Client Tutorial - Timeslider +

Figure 10 Web Client Tutorial - Timeslider

+
+
+Web Client - Timeslider dots +

Figure 11 Web Client - Timeslider dots

+
+

The interactive timeslider can be used in the following ways:

+
    +

  • panning: left click + drag or one finger drag on the bottom area (below the +horizontal line) or left and right arrow icons on the sides

    • +

  • zooming: mouse wheel scroll, two finger pinch, or plus and minus icons in +the middle

    • +

  • reloading: spinner icon in the middle

    • +

  • selecting a time interval: left click + drag or one finger drag in the upper +area (above the horizontal line) or click on a histogram bucket

    • +

  • showing the total number of available products in a histogram bucket: hover +over the histogram bucket

    • +

  • showing the footprints of all products, the first product id, and the total +number of additional products in a dot group: hover over the dot group

    • +

  • showing start and end of the current selection: left click + hold on +selection rectangle

    • +

  • zooming the map to a combined minimum bounding box of all products in a dot +group: click on the dot group

    • +
+

There are currently two ways how timeslider works connected to spatial filters:

+
    +

  • Spatially un-aware: Always shows time distribution of all available products.

    • +

  • Spatially aware: Takes currently set spatial filter (or current map view) in account when displaying histograms. That way, time distribution of products over a specific area can be evaluated.

    • +
+

In order to change between the modes, use the location switch in top right edge of the timeslider panel.

Search Results

+

The panel in the right part of the map window has a tab showing the Search +Results grouped by enabled layer(s). The search is defined by the currently +visible geographic area or spatial filter, selected time interval, and +additional filters if set. Items in the list are sorted as the catalog returns +them which typically is from the oldest to the newest.

+
+Web Client Tutorial - Search Results +

Figure 13 Web Client Tutorial - Search Results

+
+

Searching can be disabled and enabled again for each displayed layer +individually by clicking on the large button labeled N layer(s) selected to +show n/n and clicking on the corresponding layer entry (see +Figure 14) or by clicking on the Search toggle +(see Figure 15) if only a single layer is +configured.

Filters

+

There are several options to add explicit filters to product queries in the +Filters tab in the left panel:

+
    +

  • Spatial filter: allows drawing a Point, Rectangle, or Polygon directly on +the map. By default when no explicit spatial filter is set, the current map +window extent is used as a spatial filter.

    • +

  • Time filter: by default the time filter, a simple time interval, is +configured via the Timeslider. If enabled, the time filter tool allows +a fine grained configuration of the time interval to use for searching.

    • +

  • Additional filters: based on the configuration provided by the operator +additional filters for each layer based on available metadata like “Cloud +Coverage” might be available.

    • +
+
+Web Client Tutorial - Filters +

Map Layers

+

The Layers tab in the left panel enables configuring Overlays, Layers, +and Base Layers to be shown.

+
+Web Client Tutorial - Map Layers +

Figure 23 Web Client Tutorial - Map Layers

+
+

Base Layers provide various backgrounds whereas Overlays are text labels or +other information like footprints to view on top of products for easier +orientation on the map. They can be enabled and disabled individually as +needed via the eye icon next to their name.

+

Layers correspond to product collections or datasets. Searching is performed +on enabled layers.

+

The order of layers can be changed by dragging the arrows next to each layer +up and down. This influences the order of the rendering on the map as well as +in the timeslider.

+

The visualization (styling) of layers can be changed by clicking on the paint +brush icon next to the layer name. The displayed overlay enables setting the +layer’s opacity and selecting one of the predefined styles for the layer.

+
+Web Client - Layer configuration +

Details Display

+

In order to view details of individual products, either click on the info (i) +icon after clicking on the product footprint on the map or the product entry in +the Search Results panel.

+
+Web Client Details Display panel +

Figure 25 Web Client Details Display

+
+

An overlay display will open showing the product metadata as well as the product +itself on a map. The product metadata contains links to visualize and download +the metadata and product. Those links are OGC standards compliant service +requests for OpenSearch (see chapter Searching), WMS (see chapter +Viewing), WCS, and DSEO (both see chapter Downloading). The +chapter Sample Service Requests provides sample requests for all those services.

+

The following links are provided:

+
    +

  • Metadata ATOM: download the product’s metadata in ATOM format

    • +

  • Download Package: download the entire product as stored on object storage

    • +

  • WMS: GetCapabilities: get the description of the WMS for the individual +product for example for inclusion in QGIS

    • +

  • WMS: GetMap: visualize the individual product using WMS

    • +

  • WCS: DescribeEOCoverageSet or WCS: DescribeCoverage: get the description +of the product’s coverage in WCS

    • +

  • WCS: GetCoverage: download the product as coverage potentially after +adjusting the URL parameters

    • +
+

The visualization (opacity and style) of the product layer for this map window +can be changed via the Visualization button in the top left corner.

+

The product itself can be added to the basket by ticking the check box in the +bottom right of the panel.

+
+
+

Download

+

Several methods for downloading products or only parts of them are exploited by +the web client.

+

After putting one or more products in the basket or selecting them for +download, they are listed in the right panel, either on the Search Results tab +via the Selected button or on the Basket tab (see section +Search Results particularly Figure 20 and +Figure 21 above).

+

To download a full product (image and linked metadata) or a full coverage (just +the image), the Details Display of the respective product can be used (see +chapter Details Display above).

+

To download all selected products in parallel the Download or Download as +buttons on the right panel of the web client can be used.

+
+Web Client - Download multiple products +

Figure 26 Web Client - Download multiple products

+
+
    +

  • Download as: offers a Download as URL-List option which downloads a .txt +file with a list of download links (Get Coverage requests) and a Download +as Metalink option allowing for possibly increased speed via segment +downloading by metalink-aware software.

    • +

  • Download: opens an overlay panel allowing to specify download parameters +for subsetting, projection, format, interpolation, and resolution or scaling +as shown in Figure 27 below. When multiple +products are to be downloaded, the configured options are applied to all of +them. Clicking the Download button confirms the selected options and +initiates the downloads. Note, the browser might open multiple confirmation +dialogs or issue a warning. Besides, modern browsers have a limit of 6 +concurrent connections. Popups might need to be explicitly allowed for this +site.

+

Saving the session

+

The web client allows to save some parts of its current state by setting the +URL search parameters. That enables users to revisit the same view in time and +space later on or share the direct link with someone, overruling the default +client setup. Please note that certain characters are automatically URL encoded, +as URLs sent over the Internet only use the ASCII character set. This means that +if user manually enters for example : sign, while entering the website, +it will automatically transform into %3A, making the URL less readable.

+
    +

  • Pre-set the map position by setting x, y as coordinates of the center +of the map and the zoom with the z parameter. Map position example.

    • +

  • The time selection is set by timestart and timeend, and should be entered +as ISO 8601 UTC time format without milliseconds. Time selection example.

    • +

  • In case only one main layer is configured (like in the Emergency collection), +additionally custom filters can be saved via their name. In order to +investigate this option, the fastest way is to use the filter manually within +the client and copy/modify the URL parameters. Filter example.
