This view displays all the matching hits gathered in clusters which are localised on a geohash grid. Each cluster shows the local count of hits.
This view displays every feature using its actual geographical extent.
Every panel in the application allows to see the distribution of the hits over several dimensions: temporal, geographical or technical dimensions, including means to restrain the scope of the exploration by setting a selection.
Thanks to these filters, the user can easily see and interact with the products.
This widget enables the user to see the temporal distribution of the exploration hits and also define a temporal selection. A begin and an end date can be set to specify the date range with the graphical handles. The time range can also be set using the date-pickers which pop when the user clicks the begin or end date. Some usefull shortcuts are available through the panel which pops-up when the user clicks the hour-glass icon.
On the right-hand side of the main view, a collapsible panel shows details on the exploration hits.
This panel has two representations: detailed hits and previewed hits.
The detailed hits representation is a table of the matching hits with main information displayed in columns. Every row in the table has an expansion button to open a sub-panel to show additional information of the product.
The previewed hits representation is a grid of the matching hits showing the thumbnail of each hit. When the user clicks on the thumbnail, a secondary panel opens to display the quick-look of the product.
The user can switch from the preview display to the detailed information view of the product using the clickable icon. This view can be closed by clicking on the icon.
The user can switch between these two representations by clicking on the style selector.
From the detailed information view of the product, the user is enabled to trigger several actions:
Download the product
Locate the product on the map
Render the product on the map
Some of these actions are optional and their availability depend on the services provided on the selected product.
This counter shows the total number of hits that fit the selection defined by the current selection of filters.
This widget is designed to input free-text as filters. Every term available in the products meta-data is available for this kind of exploration. Each free-text filter is displayed with the associated count of hits.
Geographical filters tools
This collapsible bar displays the tools to add or remove a geographic filter as bouding box.
This shortcuts enable to trigger specific filters:
a filter on products which supports WMTS,
a filter on products which are locally stored,
a filter on products which are remotely stored.
The Donut, the Histogram or the Power Bars are interactive and allow to set filters and also display the hit counts on each part of the graphical representation. Each widget has several functions: analytically display the result of the exploration on a technical dimension but also is a mean to set a filter. For instance, the inner most ring of the Donut represents the distribution of the results over the different collections. When the user mouses over a portion of this ring, the corresponding hits count is shown. If the user clicks this ring portion, then he creates a filter on the corresponding collection: "Sentinel-2" or "CMEMS"
Collections, Type, Level donut and power bars
This widget displays the decomposition of the products on hierarchical dimensions:
the collection: "Sentinel-1", "Sentinel-2", "Sentinel-3", "CMEMS" (Marine Copernicus Core Services) or "CLMS" (Land Copernicus Core Services)
the sensor used for corresponding satellite: "SAR" for "Sentinel-1", "MSI" for "Sentinel2" or "OLCI", "SRAL" and "SLSTR" for "Sentinel-3",
the processing level: 0, 1, 2, ...
Cloud cover notation Histogram
This widget is used to display the distribution of cloud cover notations for "Sentinel-2" products. Lower and upper bondaries are respectively set to 0 and 100 by default. The user can use the handles to restrict the associated boundary and then set a range filter on Cloud cover notation.
Geographical Names Power-Bars
Each product has a geographical extent over multiple countries or local places. All these geographical names are collected for each product and displayed using this three-parts widget. When the user clicks a name, all the products which cover this country state or county are filtered. This widget enables to select multiple geographical names.
A blue chip appears on the shortcut icon when a filter is applied on the corresponding widget, we can cancel the filter by clicking on the chip.
Products which provide a WMTS service support can be displayed as an overlay on the basemap. To do so, the user selects hits either from the results list or from the map. The products are selectable from the map by doucle-clicking on their extents. They can be deselected with a second double-click. If several products overlap where the double-click is performed they are all selected. A double-click outside any geographical extent clears the selection.
Once the selection is done, the user clicks on the display products icon to activate or deactivate the selected products display. Then any product can be added or removed from the selection and corresponding displays are shown.
A layer can be shown over the layer in which are displayed the products. This layer shows additional information with a vector representation: roads, boundaries, shores, ... These additional information helps the user to locate and read to products displayed.
The basemap can be changed from this menu.
Datasets editor - Hits management
This menu enables the user to save any exploration as a shortcut which can be:
activated, created or deleted
copied to clipboard and pasted for sharing purposes
combined with each others to create a new one
Each dataset shows the number of hits it filters when activated.
