Note: This page describes an obsolete version of GPSBabel that may substantially differ from the current or development version.
This format can...
read and write waypoints
read tracks
read and write routes
This format supports:
Humminbird
waypoints and routes (.hwr files) |
Humminbird
tracks (.ht files) |
Humminbird
.dat files. (These accompany the
.png files you get when you take snapshots.
There are also .dat files generated when making
recordings, but those are not supported here.) |
If you do "save all nav data" on the device, you'll get a
data.hwr and a 000.ht file on the
flash card (on a 797 in the matrix directory).
The humminbird module can read all of these file formats, but you need to
tell it which ones to write. By default, you get a .hwr
file, to get a track (.ht file), use the
"humminbird-track" format.
Note:.dat files are read-only, they only make sense
together with their images.
Supported models:
| 797c2i SI |
(They should all work, but this is the only one tested so far.)
Known limits:
| max 12 characters for waypoint names. |
| max 20 characters for route and track names. |
| max 50 points per route. Use simplify filter (count=50 or less) if you have routes with more points! |
| max 21835 points per track. |
