Garmin Base Map
OpenStreetMap data can be downloaded to a Garmin GPS:
Some areas already have this done for you:
Download the data for the area that you're interested in.
Easiest way for small areas is using JOSM & save it as filename.osm
For larger files use http://wiki.openstreetmap.org/index.php/Osmxapi
Calculate the bounding box (Decimal degrees, S & W are negative. Use Google Earth's 'Grid' View to help)
wget -O filename.osm http://www.informationfreeway.org/api/0.5/*[*=*][bbox=min_long,min_lat,max_long,max_lat]
e.g. for Tanzania:
wget -O tanzania.osm http://www.informationfreeway.org/api/0.5/*[*=*][bbox=29,-12,41,-1]
e.g. for Liberia:
wget -O liberia.osm http://www.informationfreeway.org/api/0.5/*[*=*][bbox=-11.5,4.3,-7.35,8.6]
or get a planet.osm file from:
UTFSanitizer
This may need to be cleaned-up using UTF8sanitizer
Linux
NB Can ignore errors in other apps
apt-get install libmysqlclient-dev svn co http://svn.openstreetmap.org/applications/utils/planet.osm/C/ cd C make ./UTF8sanitizer <filename.osm >fixed.osm 2>errors.txt
Windows
Needs to have Cygwin1.dll present
- http://svn.openstreetmap.org/applications/utils/planet.osm/C/UTF8sanitizer.exe
UTF8sanitizer.exe <filename.osm >fixed.osm 2>errors.txt
mkgmap
Use mkgmap to convert this to be usable on the Garmin:
java -jar -Xmx512M mkgmap.jar fixed.osm
This will produce a file called 63240001.img. This can be copied to the CF card as Garmin/gmapsupp.img (Put the Garmin into 'Mass Storage' mode to get it to act as a CF card reader)
For more help see: http://wiki.openstreetmap.org/index.php/Mkgmap/help
Troubleshooting
If you get :
Error at line 216, col 6 Bad file format: c:\Temp\cut\63242591
then open the file & remove the repeated header from the file!
If you just get:
Bad file format: c:\Temp\cut\63242591
then open the file & convert to UTF-8 (Format menu in notepad++, if too large & it crashes, then use Cygwin/Linux:
iconv -f ISO-8859-1 -t UTF-8 filename > output)
UK
If downloading the whole of the UK (from http://nick.dev.openstreetmap.org/downloads/planet/) then this is too large to process in 1 go, so the file needs splitting.
New, untested method:
Old, tested method:
UTF8sanitizer.exe <uk-*.osm >fixed.osm 2>errors.txt md cut java -Xmx1024M -jar osmcut.jar 2 fixed.osm cut
cygwin:
for i in cut/*; do iconv -f ISO-8859-1 -t UTF-8 "$i" > "${i}.utf8"; done
java -jar -Xmx1024M mkgmap.jar cut/*.utf8 java -jar -Xmx1024M mkgmap.jar --gmapsupp 6*.img
To update a gmapsupp.img, rename it as e.g. old.img, & build the new .img via:
java -jar -Xmx1024M mkgmap.jar --gmapsupp latest.osm old.img
MapSource
The map can be made visible in MapSource using a .reg file like this one (copy the 6*.img & the 6*.tdb to c:\garmin\osm):
- OSM.reg (attached)
NB MapSource 6141 - 6156 are broken - use 6137 for now
Osmosis
wget http://dev.openstreetmap.org/~bretth/osmosis-build/osmosis-latest.zip mv osmosis-latest.zip osmosis-0.38.zip unzip osmosis-0.38.zip
To split off a smaller area from a larger osm file, use Osmosis (NB Need Osmosis-0.35 since Srtm2Osm only support API 0.5 currently!):
- http://wiki.openstreetmap.org/index.php/Osmosis
java -jar -Xmx512M osmosis.jar --rx horn_contours.osm enableDateParsing=false --sort --bounding-polygon file="sudan2pts.txt" --wx sudan_contours.osm
(2pts.txt files available from http://www.maproom.psu.edu/dcw/)
Contours
To add Contour lines to the .osm files before converting to .img:
Running on Linux:
- currently fails: "Cannot open assembly 'Srtm20sm.exe': No such file or directory."
apt-get install mono-runtime libmono-corlib2.0-cil libmono-system-runtime2.0-cil libmono-system2.0-cil libmono-i18n2.0-cil libmono-corlib1.0-cil wget http://topo.openstreetmap.de/Srtm2Osm-1.8.14.10.zip unzip Srtm2Osm-1.8.14.10.zip cd Srtm2Osm mono Srtm20sm.exe
e.g. for Haiti:
srtm2osm -large -step 25 -cat 250 100 -bounds1 17.884659 -74.668579 20.231275 -71.6584 -o haiti_contours.osm osmosis --rx haiti_contours.osm enableDateParsing=false --sort --rx haiti.osm --merge --wx outfile.osm osmosis --read-xml-0.5 haiti_contours.osm enableDateParsing=false --sort-0.5 --read-xml-0.5 haiti.osm --merge-0.5 --write-xml-0.5 outfile.osm java -jar -Xmx2048M mkgmap.jar outfile.osm java -jar -Xmx1024M mkgmap.jar --gmapsupp 6*.img
e.g. for Liberia:
srtm2osm -large -cat 500 100 -bounds3 "http://openstreetmap.org/?lat=6.47&lon=-9.35&zoom=8&layers=B00FT" -o liberia_contours.osm
e.g. for Tanzania:
srtm2osm -large -cat 500 100 -bounds3 "http://openstreetmap.org/?lat=-6.89&lon=30.59&zoom=6&layers=B00FT" -o tanzania_contours.osm
e.g. for Darfur:
UTF8sanitizer.exe <sudan.osm >fixed.osm 2>errors.txt iconv -f ISO-8859-1 -t UTF-8 fixed.osm > sudan.osm srtm2osm -large -cat 800 200 -bounds3 "http://openstreetmap.org/?lat=11.75&lon=27.37&zoom=7&layers=B000FTF" -o darfur_contours.osm
e.g. merge Kilimanjaro contours into Tanzania OSM:
srtm2osm -step 50 -cat 1000 250 -bounds3 "http://openstreetmap.org/?lat=-3.2&lon=37.2&zoom=9&layers=B00FTF" -merge tanzania.osm
e.g. merge Table Mountain contours into South Africa OSM:
srtm2osm -step 20 -cat 250 100 -bounds3 "http://openstreetmap.org/?lat=-33.93&lon=18.917&zoom=10&layers=B000FTF" -merge south_africa.osm
Can also merge data afterwards using Osmosis:
java -Xmx512M -jar osmosis.jar --rx darfur_contours.osm enableDateParsing=false --sort --rx sudan.osm --merge --wx outfile.osm java -Xmx512M -jar osmcut.jar 3.5 outfile.osm cut for i in cut/*; do iconv -f ISO-8859-1 -t UTF-8 "$i" > "${i}.utf8"; done java -jar -Xmx512M mkgmap.jar cut/*.utf8 java -jar -Xmx512M mkgmap.jar --gmapsupp 6*.img
http://wiki.openstreetmap.org/index.php/Topographic_maps_for_garmin_devices
Alternative method for creating Contour maps which doesn't use OSM:
If in the UK then can use .img files from Scottish Mountaineering Club:
To merge these with the OSM data, ensure both Maps are visible in MapSource, select all the segments (using the 'Map Tool') from each in turn, then 'Send to Device'.
The gmapsupp.img from the SD card can then be copied-back to use elsewhere. or
java -jar -Xmx1024M mkgmap.jar --gmapsupp osm\6*.img contours\*.img
