  1. GPS CommunicationSoftware GPS Mapping Program Tarpits and Tips Tools of the Trade

  2. Tools of the Trade - Part II GPS Communication Program MN Dept. of Nat. Resources: DNR Garmin

  3. Overview • The Big Picture • The Language of GPS • Review of GPS Programs • Why DNR Garmin?

  4. GPS Communication Programs • Definition: • The “middleware” that allows a GPS receiver and a computer to communicate with each other. • Not a Geographic Information Systems (GIS) Software

  5. Data Transfer GPS Field Work GIS Fire Incident Plans Cycle

  6. Overview • The Big Picture • The Language of GPS • Review of GPS Programs • Why DNR Garmin?

  7. Language of GPS • GPS stores and sends lots of data: • Lat/Long, Date/Time, Elevation, etc • Information sent to a receiving computer is the Language or Protocol • With Garmins, the choices are • NMEA and Garmin Protocol

  8. Language of GPS • NMEA – National Marine Electronics Association • NMEA 0183 standard • Streams data in text messages in the format of strings • Garmin – Proprietary messages that send additional data

  9. For This Class • Setting to NMEA if using Garmin / PDA and ArcPad • This week we need to ensure the Garmin is set to Garmin Protocol Mapping in Realtime Storing Data - Processing Later

  10. Tools and Accessories • The GPS receiver • Computer • Available COM(Communication port ) • A cable (aserial to USB adapter if needed) • Program to recognize the GPS

  11. Overview • The Big Picture • The Language of GPS • Review of GPS Programs • Why DNR Garmin?

  12. Decision Factors • All Garmins must be supported • Software support is high • Provide efficient data transfer to a GIS • Cost (Program) • Nerd Factor Scale

  13. Many GPS Program Choices Garmin MapSource

  14. Garmin MapSource • Works only with Garmins • Downloads/Uploads waypoints, tracks, routes • Low cost - $100 1:100K US Maps or 1:24K Region (Park) Maps • Limitations • Creates .mps output files • No Shapefile export

  15. Upload Garmin MapSource On Your PC Moving Map In Garmin

  16. Overview • The Big Picture • The Language of GPS • GPS Communication Requirements • Review of GPS Programs • Why DNR Garmin?

  17. Download Upload DNR Garmin and GIS • Data Transfer

  18. Summary • How GPS software fits into the Big Picture • GPS and Computers are made for each other • DNR Garmin as the preferred choice

  19. What’s in Store • Next in the series: • Mapping Programs and GIS
