Enter query parameters (acquisition date, satellite type, cloud cover and elevation angle), create your Area of interest (AOI) by drawing polygon on the map, uploading vector file, entering the coordinates or selecting from list of regions and municipalities. Then submit the query to the database. You can select scenes by clicking in the table or using select tool in the map. Selected scenes details can be shown or exported.

Using this tool, you can export AOI, selected scenes or both, into the vector format ESRI SHP or KML format. When selecting ESRI SHP format don't forget to select desired coordinate reference system (CRS). You will be able to download ZIP file containing .shp, .shx and .dbf files.

Using this tool, you can create AOI by uploading vector file in format ESRI SHP. This file can contain polygons, lines or points. File should be in ZIP format and must contain .shp and .shx file. Don't forget to select coordinate reference system (CRS), in which your data are projected. PRJ file in your ZIP file will be ignored and overriden by your selection.

Coordinates input:

Enter coordinates as "Krovak negative" (X and Y transposed, both negative). X represents west-east location, Y represents south-north location. For region of Czech republic and Slovakia X is less then Y (in absolute numbers). Example of coordinates in Czech republic: -700000,-1000000. When entering square or rectangle neighbourhood, shape could be slightly rotated.

Enter coordinates in appropriate order. X coordinate should contain zone number. Example of coordinates in Czech republic: 3500000, 5500000.

Enter geographical coordinates in WGS 84 system as following: longitude (represented by X) and latitude (represented by Y). You can choose between degree (degrees, minutes, seconds) measure and decimal measure. In case of text input only decimal measure is allowed. Example of coordinates in Czech republic: 15°30’36.00” (15.510000°), 50°18’18.00” (50.255000°).

AOI is created from minimal and maximal coordinates on both axis, which define rectangle (bounding box). East coordinate should be greater than west coordinate and north coordinate should be greater than south coordinate.

AOI is created as neighbourhood of point, which is defined by X, Y coordinates.

On the basis of selected option, AOI is created as: a) polygon, whose vertexes are defined by entered points. b) rectangle, which contains all entered points, c) line, whose vertexes are defined by entered points. Every point takes exactly one row, coordinates are separated with coma or whitespace. Example of entering points in geographical coordinates (creation of polygon - triangle, creation of described rectangle, creation of line with 3 vertexes):
14 50
14.3 50.5
14.6,50.1

AOI is created as neighbourhood of points, defined by entered coordinates. Number of created polygons matches the number of entered points. Created polygons should not intersect. Every point takes exactly one row, coordinates are separated with coma or whitespace. Example of points network creation (3 points) in geographical coordinates:
14 50
14.3 50.5
14.6,50.1

AOI is defined by shape of selected division or district. The shapes of division and districts are simplified for use in this application.

AOI is defined as point neighbourhood. The point represents location of selected municipality. At first select district, where the municipality is located. Then start entering municipality name. You can select municipality from list after entering first 3 characters. By entering more characters, you can precise this list.

Point neighbourhood is defined by rectangle with centroid in given point. You have following options of defining the neighbourhood: area/height, area/width or height/width. Width and height is limited to 99 km maximally, area is limited to 9999 km2 maximally.

Point neighbourhood is defined by square with centroid in given point. You have following options of defining the neighbourhood: edge length or square area. Edge is limited to 99 km maximally, area is limited to 9999 km2 maximally.

Point neighbourhood is defined by circle with centroid in given point. You have following options of defining the neighbourhood: radius or circle area. Radius is limited to 99 km maximally, area is limited to 9999 km2 maximally.
