Geometry types

Learn about AOIs and POIs.


Overview

To order geospatial collections, you need to specify a geometry that you want to get. Different collections accept different geometry types.

Comparison

Area of interest (AOI)

single aoi

A polygon, that is, a two-dimensional closed shape, defined by geographical coordinates. The first and last coordinate pairs of a polygon are identical. A single polygon or an upload file with multipart polygons should contain no more than 999 vertices.

Depending on the collection, you will get one of the following when ordering an AOI:

  • Full scenes intersecting the AOI
  • The exact area you defined

Point of interest (POI)

point of interest

A point, that is, a specific location, defined by longitude and latitude. A file with multipart points should contain no more than 999 vertices.

When ordering a POI, you will get a full scene centered on the defined POI.
