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

  2. Tools of the Trade - Part II GPS Communication Program Minnesota Dept. of Natural Resources DNR Garmin

  3. 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

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

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

  6. Scale • Mode of Collection • Environment 25 acres 10 mile perim. • Quantity of Units • Technical Skill Levels Unique Aspects of Fire Mapping Review!

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

  8. Language of GPS • GPS spits out lots of data: • Lat/Long, Date/Time, Elevation, etc • Information sent to a receiving computer is the Language or Protocol • Two main choices for Garmin’s • NMEA 0183 and Garmin Protocol

  9. Language of ALL GPS • NMEA 0183 Protocol • NMEA (National Marine Electronics Association) • “A standard for electrical interface and data protocol for communications between marine instruments” • String of characters • Speed of talk - 4800 baud rate See Peter Bennett’s Site http://vancouver-webpages.com/pub/peter/index.html

  10. Language of ALL GPS • Must have garmin-nmea.avi

  11. Language of ALL GPS • $GPGGA: GPS GPS Fix data • UTCTime,Lat,Long, Quality, # of SV’s, … • $PGRMM: Garmin Datum

  12. Language of a Garmin GPS • Garmin Protocol • Speed of Talk: 9600 Baud Rate • Proprietary • Supports bi-directional transfer of waypoints, tracks, etc. • A GPS Communication Program written for Garmin’s must be literate in Garmin Protocol

  13. Language Differences • Not all NMEA sentences are alike! • Manufacturers add unique sentences • Choice of program important • NMEA 0183: Datum changes with display • Garmin Protocol: Datum is WGS84 regardless of display

  14. Tools and Accessories • The GPS receiver • Data - Coordinates, Date/Time etc • A cable • Computer • Available RS-232 port (COM) • Program to recognize the GPS

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

  16. Many Program Choices • NMEA-0183 Programs • Garmin Protocol Programs Fire GEEK

  17. NMEA-0183 Programs • GPSNMEA: simple display/logging • GPSy: For Macs • VisualGPS: display of GPS status/ stats http://vancouver-webpages.com/pub/peter/idx_nmeaprog.html

  18. Garmin Protocol Programs • Waypoint+: 2002 Preferred Choice! • GarTrip • Gardown11 • GarminData Monitor • ….. • DNR Garmin: 2003 Preferred Choice! 24 + programs http://vancouver-webpages.com/pub/peter/idx_garmin.html

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

  20. Decision Factors for the Fire GPS Program • All Garmins supported • Software support is high • Provide efficient data transfer to a GIS • Cost (Program) • Nerd Factor Scale

  21. Why DNR Garmin • DNR Garmin chosen over Waypoint+ • Supports newer Garmin’s • Improvements to DNR Garmin in March 2002, January 2003 • Tightly integrated with ArcView 3.X • Nerds:

  22. Download Upload Typical Use on a Fire • Data Transfer

  23. DNR Garmin Specifications • Designed by Minnesota Dept. of Natural Resources • Communicates with all current models • Uses Garmin Protocol • Cost - Its free! • Two Programs in one! • Program • Extension

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

  25. What’s in Store • Tomorrow - next in the series: • Mapping Programs and GIS
