Converting *.ht files to something useful

(1/3) > >>

SonarGene:
Has anyone been able to convert Humminbird trackfiles *.ht) to something importable into common mapping programs? I have tried Humminbird PC as well as EasyGPS (which does not recognize Humminbird files) and GPSBabel with no success. We need to map a trackline of a boat from which a man went missing and drowned. We have done this before with Garmin GPS units, but Humminbird, well....... Any help will be greatly appreciated.

LittleGazoo:
Would you define "common mapping program"?  And what format(s) do you need?

You can download the .HT file into HumminbirdPC and that format will be .GPX, then have HBPC display the track in Google Earth.  The Google Earth track can be saved as a .KML is that helps.

Gpsbabel should be able to convert straight from the .HT to .KML also.

Humviewer can export tracs in .gpx format, the base of lot of navigation soft.

SonarGene:
The mapping program we use is FUGAWI. It will import every GPS makers tracks except Humminbird.

Another individual used HB PC and could only see 125 of the reported 21,000 plus data points. I have tried HB PC and it reports the same HT file is empty.

This track file came from a model 587 and won't display on Humviewer.
