What Is Spatial Analysis?

Spatial analysis is a quantitative study of geospatial phenomena. Its conventional ability is to manipulate spatial data into different forms and extract its underlying information. Spatial analysis is the core of GIS. The ability of spatial analysis ^[1] (especially the ability to extract and transmit spatially hidden information) is the main aspect that distinguishes geographic information systems from general information systems, and is also a major indicator of the success of a geographic information system.

As the current spatial analysis research has three major professional studies: geography, surveying and mapping, and architecture, there are different

Spatial analysis (geographic analysis) is based on

Spatial analysis is a collective term for methods for analyzing spatial data. Spatial analysis is a sign of the advanced nature of GIS systems. Early GIS emphasized simple spatial query, and the spatial analysis function was weak or non-existent. With the development of GIS, users need more and more complicated spatial analysis functions. This has promoted the development of GIS spatial analysis technology. Makes a variety of spatial analysis techniques appear. According to the nature of the data analyzed, it can be divided into:

Analysis and calculation based on spatial graphic data;

Data operations based on non-spatial attributes;

joint operation of spatial and non-spatial data.

The basis of spatial analysis is geospatial data, using a variety of geometrical logic operations, mathematical statistical analysis, algebraic operations and other mathematical methods, the ultimate purpose is to solve the practical geospatial problems involved.
