The index calculation mainly refers to the calculation of various technical and economic indicators and the generation of various statistical thematic maps.

GIS combines spatial attributes with non-spatial attributes. Using GIS technology, we can conveniently perform statistical analysis on various non-spatial attributes based on spatial data, it is very convenient to generate various types of technical and economic indicator tables, as well as various statistical topic charts, such as histograms, bar charts, pie charts, and line charts. It is very convenient and intuitive for comparative analysis of various types of data, providing data support for the planning and design of planners.

Common metrics are calculated as follows:

The first is the most basic calculation of the Land Use balance table, which collects statistics on various types of land use and provides tabulation charts.

Second, the land development intensity calculation and analysis, and the land construction density calculation and analysis. The plot ratio and building density can be calculated based on the existing Plot Area and basic building data.

Third, the calculation and drawing of various economic and social indicators.

4. Calculation and drawing of various facilities and requirements, such as water supply and power supply.

Common analyses on economic, social, and population indicators include: Population Density economic density chart, spatial-based demographic analysis (age, occupation, gender, education level), and economic structure, analysis and Comparison of the composition of three industries in different regions, industrial structure layout, and comparison of per capita output values. Analysis of urbanization levels and Development Superiority of each region (location, transportation, population, resources, and economy ).
