[mkgmap-dev] Error BeNeLul

Tue Dec 26 04:23:25 GMT 2017

Hi Henning,

reg. 2nd: I think the message is clear: "Use a larger block size with an option such as --block-size=1024 or --block-size=2048"
The value 65535 is the number of blocks, not the block size.
I am not sure why this number is not calculated by mkgmap, I'll have a closer look later.

reg. 3rd:
Yes, we probably need another option like dem-poly to tell mkgmap a polygon. Points outside of the polygon would get height 0.
I wrote this to Ervin but it seems that I forgor to copy the list.

Gerd

Hi Gerd,
I got a similar error in East Malaysia/Philippine in that tile:
63240328: 188416,5429248 to 538624,5650432

If you need o5m-file let me know.

I used:
x-dem=E:\SRTM\hgt\SRTM3v3.0
x-overview-dem-dist=276160

2nd:
After you changed the file size limit I ran in some of the problematic
tiles into:
SCHWERWIEGEND (BlockManager): .\63240185.o5m: overflowed directory with
max block 65534, current=65535
SCHWERWIEGEND (MapFailedException): .\63240185.o5m: (thrown in
BlockManager.allocate()) Too many blocks. Use a larger block size with
an option such as --block-size=1024 or --block-size=2048
It mainly happen in low data areas in China, Arabia and Australia. I'm
not so sure, if I just should increase the block-size to 128000 or is
there an limit? The examples are quite low values. Can you or someone
else gave me a suggestion?

3rd:
It seems overview-dem is generated for a larger rectangle area, not only
for the existing map area. For areas out of map area (areasa.list,..) I
would expect DEM is treated as 0 elevation.
