Mobile GIS Presentation Outline What is GIS\GPS and Mobile GIS? What we are looking for The Options GPS\GIS Demo with Survey Questions GIS – Geographic Information System A computer based system for: Capturing Storing Analyzing Querying Displaying Disseminating geographic data to provide a snapshot of reality. GPS – Global Positioning System •GPS is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations. •GPS uses these "man-made stars" as reference points to calculate positions accurate to a matter of meters or even centimeters with certain units •In a sense it's like giving every square meter on the planet a unique address. What is Mobile GIS? Mobile GIS is the use and collection of geographic data in the field on mobile devices Mobile GIS Components • Required • • • • • Hand-held computer Global Positioning System (GPS) GIS software and applications Spatial Data Beneficial • • Wireless communication network Server-side geographic analysis processing capabilities What we are looking for?
