Geospatial Data

Also known as geospatial data, geospatial data is the data or information that identifies the location, form, distribution, and more of an object. It quantitatively describes the objects and phenomena with positioning sense in the real world.

Geospatial data is usually represented in the form of point, line, surface, and body. You can run queries against spatial data to obtain the area, length, and spatial relationship of the target object.

DLI supports geometry data of the following types:

  • Point
  • LineString
  • Polygon
  • MultiPoint
  • MultiLineString
  • MultiPolygon

The preceding data types are all referred to as specific Geometry types.


Geometry queries allow you to collect the number of points of interest in a certain space range, check whether two areas overlap, and calculate the distance between two places.
