Press Change Item Order. Press Move, and move item on list. FieldReference for the Garmin GPSMAP 62 (s, st, sc, and stc) Satellite: shows satellite strength and constellation Waypoint Manager: Change name, symbol, comment, delete, etc. Waypoint Averaging: collect multiple positions for a single waypoint to increase accuracy Track Manager: Current tracks, saved tracks, portions, clear track Area Calculation: calculate, save Main Menu Download a new almanac if GPS receiver has been moved more than 300 miles while turned off OR if off for several weeks. Turn receiver on and place in location with clear view of sky, allow 15 minutes for almanac download. The almanac is automatically updated whenever the receiver is in use. • The federal datum standard for geospatial data is North American Datum 1983 (NAD83). The position format and datum should be set to match the communication used on the incident, typically Degrees,Minutes,Seconds (hddd°mm’ss.s”), NAD83 datum or Degrees,Decimal Minutes (hddd°mm.mmm’), WGS 84 datum when working with air resources.But… • If using GPS receiver with a paper map, set receiver datum to match map datum. Possibly NAD27! • If hand entering waypoints from other sources, (e.g., GIS, air resources) change coordinate system format and datum to match before creating points. To change pages press Page button (or Quit). To customize pages, go to Main Menu, pressing menu button twice. Press Setup| Page Sequence to change order or add a new page. Setup Menu Set up System, Unit, Position Format & Time Tracks: turn on/off current track Map: change map settings. Wide Area Augmentation System (WAAS) WAAS (System | GPS menu) improves accuracy of GPS positions but relies on direct line of sight to one of two geostationary satellites. Ensure GPS is held upright to maximize view of southern sky. Waypoint Naming Suggestions Position Format(including Map Datum) should be set to the communication format for the incident.

Make sure Track recording is off by selecting Do Not Record. Go back to Main Menu. Go to Track Manager, select Current Track. Scroll down and press Clear Current Track. Saved (and Archived) Tracks may be deleted individually or all at once by pressing menu while in the Track Manager. Note: Before a data collection mission you should Clear Current Track. If needed, save it or download to a PC. • The Federal datum standard for geospatial data is NAD83. When reporting position of Lat/Long in degrees minutes seconds, degree decimal minutes, or decimal degrees, include all decimal places available to improve precision. • Briefing • Plan mission to achieve the objectives. • Are mission logistics defined to execute and complete the mission? • Delivered GPS data or product format is understood.Equipment • Select appropriate GPS receiver for the mission. • Use an external antenna whenever possible. • Adequate batteries or power source. • Paper map and compass. • Notebook and pencils. • GPS metadata form. • Prepare GPS receiver • Set datum and coordinate system to NWCG (see above) or incident standard. • Update receiver almanac for the local area. • Download and delete old waypoints, active log and saved tracks if not needed to clear memory. • Set up Track Log collection interval based on method of travel and speed, and size of area to be mapped. • Check wires, connections and power source. • Verify all GPS settings are correct prior to mission. • Aerial mapping mission • Brief pilot on mission prior to takeoff. • Ensure reliable external antenna connection. • Carry spare GPS receiver and extra batteries as backup. Lines and Polygon features are mapped as the “current track” which isactually a series of track points (GPS positions). Track points may be downloaded to a computer as GISline or polygon data layers. To collect go to Main Menu| Setup | Tracks. Move to the collection starting position. Turn Track Log to Record, Show On Map. To pause logging either during the same track or between different track segments, set Track Log to Do Not Record or simply turn receiver off with power button. Press MARK to create a new waypoint. Edit the name of the waypoint: use the rocker button until the topfield is highlighted, press ENTER. Enter a name with the keyboard using rocker and ENTER button. Press Done. Averaging improves accuracy. From the waypoint screen, press MENU, then select Average Location. Stand still with antenna away from the body. Press ENTER to Start. Monitor the Sample Confidence bar and press ENTER to Save. Prepare for track collection. Go to Main Menu. Press Setup. Press Tracks. Set Record Method to Timeand Interval based on method of travel (see below). Set Auto Archive to When Full. To begin collecting data, set Track Log to Record, Show on Map. To stop recording return here and select Do Not Record. When collecting a polygon (area), stop recording just shy of the starting point. Overlap may cause issues in the GIS, and may miscalculate area when saved To deletea waypoint, go to the Waypoint Manager. Use the rocker button to scroll to find the waypoint, or press MENU to search. Press ENTER to open waypoint. Press MENU and select Delete. Go to Main Menu. Press Area Calculation to map a polygon and save in current tracks. PressStart to begin mapping the perimeter. PressCalculate to end and view the measurement. Area format (acres, sq meters, etc.) can be changed by pressing Change Units. Select Save Track to save. You can open a Saved Track from the Tracks Manager, to view on map, edit name, delete, or archive . Suggestedrecording intervals (based on speed): Helicopter: 1-2 second interval. Walking: 3-5 second interval. Vehicle: 2-3 second interval. Recording interval may be changed during mission. Use Waypoint Manager, select waypoint to project, select Menu button, scroll down and select Project Waypoint, enter compass Bearing (N=0, E=90, S=180, W=270), set distance units, set distance, save & edit, change name, view on map, click Go. Now you can navigate to the projected waypoint. The track log will immediately start and collect positions as long as “Record,...” is selected.
