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. Coordinate data represents features that have a known location on the earth. Points: X & Y Locations Polygon: Connected X & Y Locations that contain attribute information. Line: Connected X & Y Locations Raster: Row and column matrix represent geographic space. an information system for capturing, storing, analyzing, managing and presenting data which are spatially referenced

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. Coordinate data represents features that have a known location on the earth. Points: X & Y Locations Polygon: Connected X & Y Locations that contain attribute information. Line: Connected X & Y Locations Raster: Row and column matrix represent geographic space. an information system for capturing, storing, analyzing, managing and presenting data which are spatially referenced

What is Mobile GIS? Mobile GIS is the use and collection of geographic data in the field on mobile devices

Mobile GIS Components Required Beneficial Hand-held computer Global Positioning System (GPS) GIS software and applications Spatial Data Beneficial Wireless communication network Server-side geographic analysis processing capabilities To extend your current Enterprise GIS into the field, there are obviously some requirements. It requires some type of field device that is capable of running the software you need, which also implies an appropriate operating system. It requires access to GPS coordinate data through a live link to your application. It also requires appropriate software to support these applications. And finally appropriate spatial data. This will take you a long way toward a successful Mobile GIS implementation, but to get even more value, you can add a wireless communication network in order to provide the bi-directional sharing of data and acquiring access to any back-end processing that may be available from your server.

What we are looking for? Quick way to conduct survey Have data available quickly Keep track of historical data Compare and analyze data across different years Ease of use Low cost Spatial aspect (mapping)
