Search

EarthPlatform has a search panel with various customization options. Once you login with your credentials, the landing page is shown with the search filters and results panel on the left:

S. No	Label	Description
	Search Box	Enter any geographic area like "Vancouver", "Chile" etc to find and focus
	Rectangle Tool	Select two vertices of the diagonal on the map to form a rectangular area as a geospatial filter
	Polygon Tool	Select a given area as a geospatial filter on the map by creating vertices with left clicks. Click the first vertex or double-click after the last vertex to complete
	Input GeoJSON	Click to enter or import a GeoJSON as a geospatial filter

Note

The Advanced Filters panel expands with additional parameters based on the Collection selected. When there are results returned from the search, you can see the results panel populated with images, along with thumbnails if available. When you hover over a search result, the corresponding footprint will be highlighted in yellow on the map.
