Re: [mkgmap-dev] MapSource crash with DEM: Maybe tdb file needs changes?

Hi all, thanks for the input. I still have no idea what this size value might be but I agree that it doesn't seem to have an influence on the crash. I also tried changing several other of the unknown fields and found no change. I also tried to change the tdb to version 411, no change reg. crash.

Hi Gerd, > I only have one routable map with DEM data See this nice post by moderator on Garmin Forum: https://forum.garmin.de/showthread.php?49979-TopV7-Routen-aus-markierten-Wegen&p=247707#post247707 These maps work in BaseCamp, when placed on pendrive. -- Best regards, Andrzej _

Hi all, I am wondering why the DEM-features are titled „Hillshading Options“. The most valuable function of DEM (which I was missing for a long time) is the 3d-View in Basecamp when planning trips. This should be promoted with a appropriate headline :) Andreas > Am 03.02.2018 um 11:21 schri

Hi Gerd, I think it's even more in combination with DEM. I usually use 6 of my 8 cores and ending up with 10 to 12 GB of heap. So I definitely agree with you available heap somehow needs to be considered as well. Not only CPU cores. Btw. for CFD/FEM analysis the simulation is usually is faster if y

Hi It seems that mkgmap writes some constants that might be important, e.g. MapDetailBlock.java contains //01 c3 00 ff os.write4(0xff00c301); os.write(0); os.write(0); os.write(0); I've just looke

Hi Gerd Have been checking a few garmin tdbs and it appears that while the first 3 bytes remain the same for each, ie 01 00 00, the last four bytes are always different and never zero ! also ,except with mkgmap tiles, I have not come across C3 in the second byte ie a 01 *c3 *00 Nick On 05

[mkgmap-dev] MapSource crash with DEM: Maybe tdb file needs changes?

2018-02-05 Thread Gerd Petermann
Hi, Ive discussed with Frank if there might be a field in the tdb file that has to be changed. Maybe there is a value that tells MapSource something about the alignment of DEM data? I don't have a single original Garmin tdb file :-( It seems that mkgmap writes some constants that might be impo
