Soil fertility is an extremely important indicator in measuring crop growth and largely affects the crop production potentiality. By comparing the traditional fertility assessment model and the GIS assisted fertility assessment model, we conclude that the GIS assisted method based on geostatistics and GIS technology is very effective in the assessment of soil fertility and widely used to evaluate...
As the rapid development of China's highway construction, the rationality of the design of public transport routes has to face a severe test, since a static bus system can not keep up with the social life nowadays. In this article, we will talk about using the ArcGIS Server technology to develop a dynamic bus monitoring and scheduling system, which combines 3S technology (GPS, RS, GIS) together, to...
