[mkgmap-dev] mkgmap r4048 seems to fix problem with hill shading

Mon Jan 22 15:55:32 GMT 2018

Hmm, seems that part of my post got lost:
--------- DEM Tile Header ------------------------------------------------------
         |                         | Zoom level 0 Tile row 0 column 0
00000029 | 00 00                   | data section: at offset 0x000000
0000002b | 00                      | minimum (base) height: 0
0000002c | 00 00                   | max height delta: 0
--------- DEM Tile Header ------------------------------------------------------
         |                         | Zoom level 0 Tile row 0 column 1
0000002e | 00 00                   | data section: at offset 0x000000
00000030 | 00                      | minimum (base) height: 0
00000031 | 00 00                   | max height delta: 0

Hi,
maybe we have to set a special flag when we write "no data" tiles (all
heights 0m) with headers like this:

Both mkgmap and BuildDEMFile write them.
