Abstract: The karst mountainous areas have fragmented landscape, rugged terrain and cloudy and foggy climate. It is difficult to monitor crops rapidly through conventional remote sensing methods in a large scale. In response to this situation, the GMG collaborative system integrating internal and external industries was developed. Using the precise positioning of GPS, rich semantics of multimedia and advantages of GIS data processing, the remote sensing monitoring of agricultural industry has been driven multi-directionally in Guizhou province. Practice shows that the system quickly realizes the diversity of interpreting samples in provincial monitoring, effectively compensates for the limitations of remote sensing monitoring in local areas and checks the accuracy of interpreted data in real time simultaneously.

Key words: agricultural industry monitoring in mountainous areas, remote sensing image interpretation, GMG collaborative system, multi-directional drive
