Forest disease location system based on GIS and PTZ

The research design explains that forest diseases and pests cause great economic and environmental losses to the society. In order to prevent it, obtain accurate, timely information and save manpower, a participatory survey model for forest diseases and pests is proposed. The system includes a video positioning system and manual identification work with a mobile GIS embedded in a PDA. The video system is effective for scanning the area, especially where there are withered trees. In order for workers to be able to inspect the disease control in the disaster area with a PDA, we developed a positioning algorithm and a positioning system. The positioning algorithm is based on DEM and PTZ camera. In addition, the accuracy of the algorithm has been verified. The software is composed of a ۳D GIS subsystem, a ۲D GIS subsystem, a video control Sub System and a disaster positioning subsystem. The ۳D GIS subsystem can provide thematic maps of disasters. The video control subsystem can remotely switch the digital camera to focus on the suspected area. The implementation of the disaster location subsystem and algorithm has proven to be able to detect forest diseases and pests in practical application for the forest sector.
