Hi all,
1) The current code (only) writes a log message with severity WARNING for a
missing hgt file:
"file xxx.hgt not found. Is expected to cover sea."
I wonder if we can create a list of files that can exist or maybe a polygon
that can be tested so that
tiles which are knwon to cover land are
Hi Andrzej,
I think your patch increases the box too much. I think we only need an aligned
upper left corner.
See my attached version.
Still, even with my patch DEM size can increase quite a lot. I've created a map
of bolivia with without --dem-dists option.
Size of gmap folder:
223.511k with r4
Hi Andrzej,
thanks, fixed with r4061:

Hi,
addition: mkgmap compiles this example, if I remove --dem-dists.

Canary Islands contains a single tile, that's why I saw no effect:-[
Spain map now has non-rectangular overview covering only map tiles. No
mouse hover, as reported by Henning.

Hi Carlos,
if your map contains multiple tiles that form a rectangular shape
than the 0x4b polygons are combined again into one rectangle
by ShapeMerger.
Your map of spain looked different (empty area in part of portugal),
so in that map you should see a different 0x4b polygon.

MapEdit shows a rectangular map coverage area polygon from r4056, see
attached screenshot. May be I'm doing something wrong.

Hi all,
thanks for testing. Size changes can be caused by block-size change, but also
a non-rectangular shape requires a few more bytes.
You can use GpsMapEdit to check this.
I'll continue experimenting with non-rectangular 0x4a an d0x4b shapes during
the next days.

I have tested single layer map and also OSM layer+contour (transparent)
layer, and I don't see any difference in MapSource. Contour lines are
cut with the same poly than OSM data. Only difference is that overview

Hi Gerd,

Yes. Linear interpolation is averaging too. If DEM can use exact values
form HGT, then there will be no averaging. Even interpolated values near
HGT node should be the sa
Hi Andrzej,
If I got that right you just want to achive that the
calculated postions are as close as possible to the positions in the hgt file.
If you request a point that is not within the original area I would expect
trouble
(either NPE or wrong height 0).
If that can happen, you should create
Hi Gerd,
> why you don't use the modified area for the hgtConverter as well?
I need HGT resolution first. I guess resolution comes after
initialization of hgtConverter. Probably area for hgtConverter should be
expanded, or maybe initialized with a bit bigger area?

Hi Andrzej,
did not try the patch but I wonder why you don't use the modified area
for the hgtConverter as well?

Hi Gerd,
I have attempted to reduce interpolation, when DEM pixel size is the
same as HGT pixel. I have stretched a bit area of DEM, so edges are
aligned with HGT. I'm attaching a patch.
Resulting map looks similar, only shading has moved a bit. I'm not sure
if this is the result of differen
Hi Henning,
I would expect differences when you combine a normal map with transparent tiles
containing contour lines
and those tiles overlap the normal tiles.

With using --transparent I can't see any differences compared to older
mkgmap versions.

Hi Gerd,
seems to work for me, but I also don't know what I should expect to see.
In BaseCamp/MapSource the map is still in rectangle shape with light
yellow coloured back ground in the area without data. Only difference
is, that there is no more mouse over, indicating the mouse is in

Hi Andrzej,
ah, okay, so I looked at the DEM data created by GMapTool.
I already wondered where this came from ;-)
So forget those findings for Winter Activity Map.
Still, Adria map seems to use the same trick, just not so strange values.

Hi Gerd,
do you have overview for Winter Activity Map? I have never seen Winter
map for PC, only gmapsupp.img. Maybe it is an overview created by
GMapTool, check copyright in TRE.
I have included procedure for creating empty DEM in GMapTool, which is
using different distances. Actually it u
Hi Andrzej,
thanks for the hints.
It seems indeed to be an alternative to use a very large overview-dem-dist
value in combination with no DEM data.
Garmin uses this in the "Winterkarte" and in the Adria Map.
Also, the overview map of "Winterkarte" is the first map that I found in which
dem-dist
