[mkgmap-dev] Raise an error when levels and dem-dists mismatch

Wed Jul 13 06:22:03 BST 2022

Hi Daniel,

OK, I've added a corresponding check in r4905. Hope the error message is clear enough?
With your example I see now:
SCHWERWIEGEND (global): More dem-dist values than levels:
        [3312, 6624, 9936, 13248, 16560, 19872, 23184, 26496]
        [L4 B16, L3 B18, L2 B20, L1 B22, L0 B24]
 (thrown in MapBuilder.buildDem())

ciao,
Gerd

Hi Gerd,

yes, I can confirm that a smaller dem-dists count is no problem. So I
change my request to a validity check for dem-dists-levels <= levels.
