| Abstract: | According to the practical demand of the national second land surveying,we put forward the land information collection system based on GPS/PDA,clarifying its design,structure,function and the work flow. Applications into actual cases demonstrate that the system is accurate in fieldwork positioning and data recording with even positioning precision,in-the-field drawing,digital saving of input attribute and data. The survey data are more precise,the work process is easier,the wok efficiency are improved evidently,and the land information has a high practicality. As a new technology of land surveying which integrates homework and fieldwork,it is of great significance for the improvement of national resource technology support system. |
