Practical Applications of GPS Technology
- 1. Practical Applications of GPS Technology adam mckinney Intertribal Agriculture Council Conference August, 2012
- 2. Global Positioning System Satellite navigation providing location and time information in all weather, anywhere on or near the Earth. Developed in 1973, fully operational in 1994. Originally 24 satellites, currently 31 satellites in operation. A GPS Receiver requires line of sight access to at least 3 satellites for a 3D (latitude/longitude/altitude) fix.
- 3. Case Study: GPS Asset Management Nearly any asset can be tracked with GPS. Example: Fleet management. Information from tracking targets collected using GPS data can be mined for cost-savings and usage statistics. Automated tracking of maintenance intervals, fuel cost/usage, and real time location awareness
- 4. Smart Phones: GPS in Hand Asset management: Geo-Tagged Photos/Information Inventory management/Loss prevention Personnel management: Employee tracking Time management Cost analysis and planning: Fuel cost analysis Efficiency planning and management
- 5. Geographic Information Systems GIS is Software that allows manipulation of GPS data for display or export—Do MORE with GPS information! Repositories exist for USDA/State Data with coverage maps ready to use; INSIDEIdaho.org Google Earth ESRI ArcGIS/ArcMAP Q-GIS/MapWindow
- 7. Case Study: Road Hazards in Pocatello Data was collected using a Linux-based handheld PDA with built in GPS receiver and ttMaps open source software. Data was also recorded manually at collection points along with additional attributes; Depth, Area, Street, etc. Latitude and Longitude collected in decimal degrees; area and depth measurements collected in inches. Data imported in to ESRI ArcGIS and displayed using USDA Satellite imagery from INSIDEIdaho
- 9. Case Study: Unique Analysis using GPS Total length of streets in the study area: 9,439 ft Total area of those streets (based on 30’ street width): 283,170 ft2 Total area of all road hazards in the study area: 3,140 ft2 Total percentage of road damage or prior damage: 1.1% Street with the most road patches: Hayes, 14. Street with the most potholes: Day, 5.
