What is geospatial data?
When a set of data encompasses geographic location as the reference component, it is referenced to as geospatial data. It represents some information about a specific location or over a range of a given location. The location can range from a specific point to a larger area. Oftentimes, GIS and geospatial data are interchangeably used.
GIS is a programmatic system that creates, stores and analyses geospatial data.
