Recording and Displaying Waypoints
- Use the eTrex HC series quick start guide to record Waypoints. You can check out a copy of the quick start guide from the Spatial Data Center.
- Once you've recorded them, navigate to the Find function in the Main Menu.
- Select Recent Finds from the available options. A list of the recently recorded Waypoints will be displayed.
- Highlight a Waypoint and Click on it with the Rocker Key to select it. Selecting the Waypoint will display the Note (Name), Location (Latitude/Longitude), Elevation, and distance from your Current Location.
Reading the Waypoint Data on the eTrex
When reading the latitude and longitude data from the Waypoint recorder, remember the follwoing information:
Latitude
- Latitude refers to the Y coordinates in ArcMap.
- They are represented on printed maps by horizontal lines. A simple mnemonic device for remembering this is "LAT is FAT."
- Latitude will be displayed as either N (North) or S (South) on the eTrex.
- In ArcMap, Southern latitude values are indicated with a "-" (minus) sign. In the eTrex unit, the minus sign is replaced with a "0" (zero).
Longitude
- Longitude refers to the X coordinates in ArcMap.
- They are represented on printed maps by vertical lines. A simple mnemonic device for remembering this is "LONG is TALL."
- Longitude will be displayed as either E (East) or W (West) on the eTrex.
- In ArcMap, Southern latitude values are indicated with a "-" (minus) sign. In the eTrex unit, the minus sign is replaced with a "0" (zero).
The eTrex records latitude and longitude in Degrees, Minutes, and Seconds. If you want to use data collected with the eTrex in ArcMap, you will need to convert these latitude/longitude data into decimal degrees.
