The Change of GIS Platforms

• Mobile GIS refers to an integrated software/hardware framework for the access of geospatial data and services through mobile devices via wireline or wireless networks (Tsou, 2004).

(Notebooks, PDA, Tablet PC, Pocket PC, etc.)

WHY mobile GIS – Field works: data collection and validation

process, coupled with GPS and wireless communications.

– Real-time update / change– Global Positioning System (GPS) integration.
