Spatial data is any kind of information that refers directly or indirectly to a certain place or area on Earth. Spatial data, also called geospatial data or geographic data, is a set of numbers that can be used to represent a physical object in a geographic coordinate system. However, spatial data is a lot more than just the spatial part of a map.
Types of Spatial Data
There are several types of spatial data, but the most common include:
Geometric data is a type of spatial data that is represented on a two-dimensional flat surface. Geometric data in floor plans is one example. Google Maps is a navigation app that uses geometric data to provide precise directions. It is one of the simplest ways that spatial data can be used.
Geographic data is information that has been mapped around a sphere. The sphere is usually the planet Earth. Geographic data emphasizes the connection between latitude and longitude and a specific object or location. A global positioning system is a well-known example of geographic data.
Vector data is a type of spatial data that consists of points, lines, and polygons.
Point Data: Point data consists of two coordinates and can be represented on a graph as an X, Y pair.
Data on the Line: On a map, line data are lines that connect one set of points to another.
Polygon Data: Polygons are polygonal shapes cut from the earth's surface. These types of spatial data typically depict large features such as lakes or mountains. They provide information such as size, area, and elevation.
