What Is Geospatial Data?
Geospatial data refers to information that is linked to specific locations on Earth. This data is primarily represented through coordinates such as latitude and longitude but can also be derived from maps, satellite images, and GPS systems. Geospatial data allows us to identify, analyze, and visualize the relationship between different objects, regions, or phenomena on the Earth’s surface.
Different Types of Geospatial Data
Geospatial data can be classified into two main types:
- Vector Data:
- This type of data represents geographic features as points, lines, and polygons. For example, a road network (lines), a city (point), or a park (polygon).
- Applications: Used for mapping and analysis tasks that involve boundaries or routes.
