Abstract: Data acquisition is a basic problem of GIS application developing. To efficiently collect the various data information, an overall embedded GIS data acquisition system was designed. It is based on Linux operating system, using QT which is a GUI designing software, and supported by MapGISEMS3.0 which is an embedded GIS platform. Firstly, function modules were rationally divided by analyzing the needs. Then, the specific function programs were implemented, such as various spatial data accessing, GPS data parsing, and so on. Graphical interfaces for manmachine conversation such as map browsing and data editing were also achieved. Finally, the program was successfully transplanted into the target boardARM processor. The testing result proves that the system can satisfy the location service demand and the basic information collection such as point, line and region.
Key words: embedded geographic information system(GIS); spatial data acquisition; global position system(GPS)
