2 Presentation Outline What is GIS\GPS and Mobile GIS? What we are looking forThe OptionsGPS\GIS Demo with SurveyQuestions
3 GIS – Geographic Information System A computer based system for:CapturingStoringAnalyzingQueryingDisplayingDisseminatinggeographic data toprovide a snapshot of reality.Coordinate data represents features that have a known location on the earth.Points: X & Y LocationsPolygon: Connected X & Y Locations that contain attribute information.Line: Connected X & Y LocationsRaster: Row and column matrix represent geographic space.an information system for capturing, storing, analyzing, managing and presenting data which are spatially referenced
4 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 unitsIn 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 LocationsPolygon: Connected X & Y Locations that contain attribute information.Line: Connected X & Y LocationsRaster: Row and column matrix represent geographic space.an information system for capturing, storing, analyzing, managing and presenting data which are spatially referenced
5 What is Mobile GIS?Mobile GIS is the use and collection of geographic data in the field on mobile devices
6 Mobile GIS Components Required Beneficial Hand-held computer Global Positioning System (GPS)GIS software and applicationsSpatial DataBeneficialWireless communication networkServer-side geographic analysisprocessing capabilitiesTo 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.
