[mkgmap-dev] Again - java.lang.ArrayIndexOutOfBoundsException: on DEM creation

Fri Apr 13 15:56:39 BST 2018

Hi Felix,

thanks for repoorting. I think this happened with tiles at 180°.
Please use r4160 or r4161 (overlaps branch)

Gerd
P.S. A cycling map in this area ?

Betreff: [mkgmap-dev] Again - java.lang.ArrayIndexOutOfBoundsException: on      DEM creation

On compiling contourlines with DEM of Antarctica - I get this error:

It happens with:

I've uploaded the style srtm (though that is largely irrelevant I guess) and the 3 offending pbf files here: https://openmtbmap.org/broken.zip
Even though I guess to reproduce you also need the hgt files.

I also get this error on a couple of pbf tiles created by splitter and phyghtmap of Russia (and therefore also on Asia continent).

I'm not sure if the fault is in the pbf or in the hgt - As I don't know which hgt file would be coressponding here is the command used with phyghtmap - it will download the relevant hgt files.
