AOI (Area of Interest)
An AOI is the geographic area you want to analyze or request data for, defined by a boundary such as a polygon or bounding box.
Also known as: Area of Interest
Expanded definition
AOI stands for Area of Interest. It is usually defined as a polygon, a bounding box, or a set of administrative boundaries.
AOI definitions matter because they determine what data is pulled, processed, billed, or summarized. Small geometry mistakes can lead to missing coverage, extra coverage, or misaligned statistics.
When sharing AOIs across tools, coordinate reference system and geometry validity are common pitfalls. A clean AOI is typically a valid polygon in a known CRS, with units and area interpretation clearly understood.

BBox (Bounding Box)
A bounding box is a rectangle defined by minimum and maximum coordinates, commonly used to specify an AOI.
Polygon
A polygon is a closed boundary used to represent an area such as a field, region, or administrative unit.
CRS (Coordinate Reference System)
A CRS defines how coordinates map to locations on Earth, including the projection and datum.
Vector
Vector data represents geometry as points, lines, and polygons, typically used for boundaries, roads, and field parcels.
