Developing GIS applications on PDA

Abstract

The Integration of GIS software, GPS and mobile communication devices creates a "Mobile GIS" concept.  This paper presents results achieved in developing a prototype Mobile GIS. The System was developed using client-server architecture. Application on client side was built on Personal Digital Assistants (PDA) based on programming language C#. Client and server connects through connection-oriented sockets using TCP/IP protocol. Map Database on Server side is SQL Server 2005 and on PDA side is SQL Mobile Database of Microsoft. Main functions include displaying Map, querying and updating  map information and specially allowing data exchange between PDAs, or between PDA and Server.
