Also GPSmapedit 1.0.66.7 has this capability and is much faster in decompiling the img.Ĭonverting pseudo-NT to non-NT is better as you can use the maps (img) in any non-nt "whatever" map program you wish or need!!. SO the info inside the pseudo-NT and non-NT img is the same except for the headers of the subfiles. BUT these map fail to load in GPSmapedit.Ĭomparing the files (pseuso-NT/non-NT subfiles) THERE IS A DIFFERENCE in the headers. If now, using GMapTool, i join these "from NT" subfiles i get an img garmin map. (for the moment i can do this by previously knowing each file zise, because i have the non-NT version also!!. So i can create TRE,RGN,LBL files extracting the info from the GMP file. (this is located in the GMP file as i put here, one segment after another) In this example i have both files pseudo-NT and non NT, so it should be easier comparing both. So if i happen to have a pseudo-NT map and if i could extract the RGN,TRE,LBL(NOD etc.) from its. Let me explain: the idea is to convert pseudo-NT to NT maps. Then, using GMapTool 0.8.143, splited both img to their respective subfiles (you can extract each subfile from the img directly, but to be sure.) What i did was, compile the img with and without NT enabled using cgpsmapper 0100d and get: I use as source map one that came in cgpsmapper 0100d installation folder here: (this apparently was a bug in GPSmapedit, because neither earlier versions or newer version can decode pseudo-NT, only this 1.0.66.7 specific version)
I know it is possible because GPSmapedit version 1.0.66.7 can interpret and decode pseudo-NT created by cgpsmapped (which is not the real NT from garmin that can't be decoded by any program at hand)
