Maps & Geospatial Data

Geospatial Data

Geospatial data is any data that has geographic location as one of its attributes. More specifically, geospatial data is information about the locations and shapes of geographic features and the relationships between them, usually stored as coordinates and topology and represented by vector (point, line, polygon) and raster (grid) data models.

A Geographic Information System (or GIS) provides a framework for collecting, organizing, and joining geospatial data and related information so that it can be visualized, analyzed, and shared.
