In order to meet needs of information acquisition and processing of the vehicle-borne system, a crop growth spatial analysis software for vehicle-borne system was developed. The software system was composed of four functional modules: spectrum file management, canopy spectrum analysis, dynamic monitoring and spatial data analysis. It could read a variety of file types. It also could apply two kinds of spatial information analysis methods and had an interface for expert database. The proposed system was set on crop growth spatial platform to verify the effect of growth spatial analysis system for corn. Field test results showed that the system could generate crop and wheat growth distribution map and interpreted working prescription map correctly. It indicated that the system provided good technical support for the precision management of field crops.
