NGC-IAS: Integral Analysis System of National Geographical Conditions

1. Summary

 I was the key member of the development team of NGC-IAS (Integral Analysis System of National Geographical Conditions). As a large GIS analysis system developed from the bottom, NGC-IAS consisted of 11 independent toolboxs, each of which offers multiple computing functions, and I was independently responsible for the development of land expansion simulation toolbox and landscape index calculation toolbox. The system has been put into use in geographic information related departments of Beijing, Shanghai, Guangzhou, Shenzhen, Chongqing et al., and effectively improves the working efficiency of national geographical conditions analysis.
