[mkgmap-dev] mkgmap r4010

Hi Arndt,

Good point. I think I can add code to search in multiple directories, for now you have to put them into one dir.
Note that 1'' files and 3'' files have the same name, so if you want to use the 1'' files make sure
that you don't replace them by 3'' files.

This is fantastic, thank you for this work!

I don´t understand anything what you do, but it works and my maps looks much better.

I use phyghtmap to get the hgt Files. phyghtmap stores the files in 4 folders, view3, view1, srtm3 and srtm1. Can i tell x-dem to look in all 4 folders? Or must i copy all hgts in one folder?

I've just committed r4010. I think I found the bug that caused the wrong reliefs or empty rectangles.
Next step is to calculate multiple levels.

@Frank: I forgot to make the number of zero bits depended on the previously calculated plateau length.
The corresponding code in your program
if (iPlateauLengthBinBits >= 0) // bei Plateaufollower weniger Bit erlaubt
lbits -= iPlateauLengthBinBits + 1;

I think that this makes only sense if a BigBin value changes something, e.g. resets a flag or increases/decreases
a counter. Else it would just be a waste of space. I think you mentioned something like that in the pdf as well.
