Lai Li-fang · Cehui kexue · 2011
Based on the analysis of current land use change survey that the direct field investigation and plotting leads to the separation of indoor and field work,this paper put forward a mode which combines GPS,PDA and ArcPAD to serve the land change investigation.Based on the requirement analysis,the logic structure design was put forward for the storage of PDA,studied the data structure of system development methods,and further discussed the solution of the coordinate conversion in GPS collection.This research gave a reference to changing the current change mode,improving work efficiency,and reducing the error caused by the separation of indoor and field work.
