Hi Nick,
seems that something goes wrong with the dem option, it seems to contain only a
blank.
No idea what goes wrong, maybe you have repeated the option --dem somewhere?
Please post the full command.
Gerd

Hi Gerd
I now get

Hi Nick,
yes, the message looks that strange because the variable "dir" is empty or
maybe contains a blank when this code is executed:
File f = new File (dir);
if (!f.exists()) log.error(dir, "does not exist");
The file name for the *.pbf is added by the logging method, because the dem
option is parsed for each osm input file.
With r4039 I've changed the code for the error message to this:
log.error("extracted path >" + dir + "< does not exist, check", dirsWithHGT);
Please try to reproduce the error with r4039 and let me know what it reports
now.
Gerd

Hi Gerd
I'm merely questioning the phrasing of the message -, ie it wasn't the
pdf that was causing the problem as the msg implied.

Hi Nick,
I cannot reproduce that message without using a wrong option like
dem=path1,,path2
(extra comma)
Anyhow, I try to improve the message.

Hi Gerd
I used
dem=e:\dem\europe\
overview-dem-dist=88888
dem-dists=3312,13248,26512,53024
dem-poly=F:\garmin\ukraine\areas.poly
when I added the required .hgt files it worked OK

Hi Nick,
I think this message may appear if you have blanks in the option --dem. What
exactly do you use?

Hi Gerd,
Just come across a misleading error message:
SEVERE (HGTReader): F:\garmin\maps\ukraine\12345700.osm.pbf:
does not exist
Number of MapFailedExceptions: 0
Number of ExitExceptions: 0
The pbf existed, as it produced the map with out DEM !
However,some of the .hgt files were missing which caused the error.
Just a minor point

Hi all,
I did not note this before, but there is probably a typo in this description:
overview-dem-dist=888888 is far too high, I assume Arndt meant 88888.
Besides that I think there is need to use --dem-poly in combination with the
poly file created by splitter.
This poly file just describes the outer boundaries of the tiles, and mkgmap
calculates this polygon anyway.
The --dem-poly can be used with the rather complex *.poly files from geofabrik.
I've tested with bolivia.poly which has 1176 nodes
and the additional tests for the polygon bounds did not take long. Still, you
may want to draw your own simpler poly files because those from
geofabrik are rather close to country borders.

Hi Mike,
it´s simple:
- Download hgt files )*
- give mkgmap the option x-dem=path to the hgt files
- x-dem-dists=3314,4000,6000,8000,10000,15000 (maybe other values are better)
1 value for each level (options file: exampel levels = 0:24, 1:23, 2:22, 3:21,
4:20, 5:19)
- x-overview-dem-dist=888888 writes DEM to the overviewmap (maybe other value
is better)
- x-dem-poly=path to a poly file for example areas.poly from splitter result.
That´s all.
)* hgt files are downloadable here: http://www.viewfinderpanoramas.org/dem3.html
I use phyghtmap to create SRTM contourlines as .pbf. the program download hgt
files from viewfinderpanoramas to build the pbfs. After that you find a folder
hgt on your pc with hgt files inside.

Hi all,
I've been following the discussions of DEM with interest, but have so far
not attempted to create a map including this. Is there a guide to the steps
involved in producing the DEM data? I have contour data in OSM format - is
there a simple way to get this into a suitable input format (or is there a
specification of the input format available, so I can knock up something to
convert it)? I'm assuming that the height data contains the same information
as contour data but in a different format.
Thanks,
Mike
