Have at least 3 points each, so add a couple of points to an existing track then split them off). Points are OK, but not lines (but you can split a track into two so long as the new pieces Get filled in, buttons are not desensitised when they should be. Things are not always updated correctly etc. I know loads of stuff that still needs attention.

There is a partial manual evolving Further Development Can read tracks/points direct from some Garmin GPS receivers.Can track current position in real time with some Garmin GPS receivers.Knows something about the world being curved.Allows you to warp one set of map data so it aligns correctly with another set of data.Įxample being to fix data estimated from images or maps against correct ground tracks. Holds 2 sets of map data, one as a reference which is not written out or editable to allowĭata to be used as a reference without including it in the data set.Versioned save, so you don't overwrite old saves.Editing of track, point and area features.Creation of area features from line features.MP files (GMAP native format an dthe format for the cGPSmapper compiler) Load and merge tracks and points from KML files (eg googleearth), GPX files (eg uploaded GPS tracks, gpsbabel, mapsource etc) and.I have newer code, I've just not got around to releasing it. Note that I've not updated this page for a while. The development of GMap is at an alpha stage, however it can easilly be used to buildĪ map from tracks, or other data and feed it into the map compiler. To do the 3rd section and I use my Garmin GPS to get the raw data with. I'm working using the cGPSmapper compiler It provides a graphical interface toĮase the manipulation of the data. GMap currently fills the 2nd of these 3 tasks. You then have to compile the map data into a file to load into your GPS.You have to merge that data, cleanit up, annotate it and classify it then convert it to.To create a map to load into your GPS there are a number of stages GMap is available as a binary release for Linux free. mp polish map format files suitable for compilingīut I've used it to build some fairly complex maps that I've then used in anger. GMap is a Map editor for GPS maps that runs on linux.
