Mobile Geographic Information Systems (GIS) is an outcome of integrating GIS, wireless communication, embeds and mobile computing technologies. Based on .NET Compact Framework and GPRS a Mobile GIS with own patent is developed. Services in the system include: downloading map by General Packet Radio Service (GPRS), defining geographical coordinate system of maps, Global Position System (GPS) connection...
A mobile GIS for field data collection is a system which can facilitate the entire process from indoor preparation, data collection, to data processing. It is a combination of positioning and wireless communication technologies. The paper aims to demonstrate how to design and implement such a mobile GIS. Data of the system consist of three parts: background reference layer, with which spatial reference...
