Mobile and Wireless GIS Based Upon Independent Development

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 and information dynamically showing on map, sharing users' GPS information through SMS (Short Message Service) to establishes communication between system users, vector feature map and related property data editing and shortest route planning. The system is now used in field data collection and simple navigation. This paper introduces the implementation of some basic GIS services in mobile environment. And some implemented services are presented and studied in detail.
