3. According to the information reflected by map data and the concepts of map entities and attributes, map data can be divided into spatial data and non-spatial data.
Spatial data is also called geometric data, because it corresponds to the basic elements of the map, that is, entities. It is used to express the position, shape, size and distribution of objects, and it is a quantitative description of things and phenomena with positioning significance in the world. According to the different storage organization and processing methods of map data in computer system and the geometric characteristics of spatial data itself, spatial data can be divided into graphic data and image data.
Non-spatial data mainly includes thematic attribute data, quality description data, time factors and other semantic information about attributes. Non-spatial data is a semantic description of spatial information, which reflects the essential characteristics of spatial entities and is an important symbol of the difference between spatial entities. Typical non-spatial data, such as the name, type and quantitative characteristics of spatial entities.
