1/10/2024 0 Comments Qmapshack garmin img nt formatI can get them by knowing where RGN, NET, NOD starts using the 0x15 offset value in their respective header. So what i did, with a pseudo-NT file, i retrieve the gmp subfile and start extracting each subfile within it (TRE, RGN, LBL, NET, NOD). On the contrary cGPSmapper 0085 don't like it, failed, probably because it uses a different algorithm (to retrieve the data) and get confused about the zeros. Gpsmapedit opened it without any problem!!! It was later removed by the developerįor the moment instead of changing offsets values in the header, i retain absolute offset position of the data just adding a bunch of zeros between the header and the "body" (real data). PS2:I attach it here if anyone want to take a look at it (GPSmap0085.zip) The last version that has the option to decompile non-nt img maps. I have the program but i don´t have the patch, it is in demo mode. PS:by the way, does anyone has the patch for cgpsmapper 0085. #The subfiles extracted from 48580011.GMP using a HEX editor NT.LBL #The subfile splited from exampleNT.img using GMapTool 0.8.143 48580011.GMP #The subfiles splited from example.img using GMapTool 0.8.143 48580011.LBL mp map from:"cgpsmapper 0100d installation folder"\gdansk_routing\MP_source\gdansksopot.mp example.img #non-NT created with cgpsmapper 0100d exampleNT.img #pseudo-NT created with cgpsmapper 0100d Info of what is each file (this info is also in the zip) example.mp #original. 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) I'm trying to know how to convert pseudo-NT (by cgpsmapper) to non-NT garmin maps. Note 2: if anyone have GPSmap0085 ROUTABLE version, please share here END Note: The only version available on the web of program is the FREE version (NOT the ROUTABLE), so you can get the map with house numbers, but you cannot get the routing info.Įventually, combining what you get from GPSMapEdit (here you get all map info, including routing, but NOT house numbers) and GPSmap0085 FREE (House numbers, but NOT routing) you could get a full map, but this need programming. img file you obtain, CAN BE OPENED with OLD GARMIN UNITS (NT unaware) and with any map editing/decompiler program that opens non-NT mg's files.Īnother useful program is GPSmap0085 (specifically this version 0085) that let you extract house numbers from the. Now, for example, you can open it with any version of GPSMapEdit, edit and save it as a *.mp format or any other thing that you want to do.
