--route and --transparent

Hi all, as pointed out here [1] those two options should not be used together. I first thought that mkgmap should simply stop when this combination is used, but maybe this will cause problems for those who use a standard options file containing the "route" option and use that also to create transparent maps with contour lines? I think those maps will have almost empty NET and NOD files, but probably they work well? So, maybe mkgmap should only stop when NOD really contains data and the transparent flag is set?

Hi all after playing a little bit with the syntax of "conf" and "subst" i finally found a solution, which suits for my needs : power=generator & generator:source=wind { name '${manufacturer} (${ref},${height|subst:"m=>"} m)' | '${manufacturer} (${ref})' | '${manufacturer} (${height|subst:"m=>"} m)' | '${manufacturer}' | '${ref}' | '${height|subst:"m=>"} m' } [0x5912 level 2] A sentence like this works for me, thanks for your hints Am 15.02.2018 um 19:44 schrieb Gerd Petermann: > Hi Manfred, > > your rules work, but only when a lower case m is used in the OSM data. > Can't say much more because you did not post the rules which use the > tags mkgmap:ele or mkgmap:height. > > Gerd > > > ________________________________________ > Von: Manfred Haiduk <mhaiduk(a)t-online.de> > Gesendet: Donnerstag, 15.

Need help with string handling in mkgmap
by Manfred Haiduk 15 Feb '18

15 Feb '18

Hi, i'm struggling with the following problem and until now, i didn't find a solution. It seems, that in osm sometimes the height or elevation tag is filled with the unit sign, i.e 'm' and sometimes not. So with my current point file i either get elevation without the unit letter or with double unit letter - i.e 'Mm'. How to handle this ? I tried with this height=* { set mkgmap:height='${height|subst:"m=>"}'} ele=* { set mkgmap:ele='${ele|subst:"m=>"}'} but it doesn't work -- Mit freundlichen Grüßen ##################################################### Manfred Haiduk, Zum Fischbach 9, 52393 Hürtgenwald e-mail mhaiduk(a)t-online.de #####################################################

Creating a map with contour lines and DEM
by Bernhard Hiller 15 Feb '18

15 Feb '18

I was trying to create a map of Taiwan including DEM data and elevation contour lines. The DEM part was easy. But strangely, I cannot get elevation contourlines. I downloaded hgt data from Viewfinder Panoramas, and placed them into the cache directory of srtm2osm. I called srtm2osm in a batch file: SET SRTM="C:\Program Files (x86)\OpenStreetMap\Srtm2Osm\Srtm2Osm.exe" SET OUTPUTDIR=E:\Maps\Raw\Taiwan.DEM\ %SRTM% -bounds1 21.81 120 23.6 122.1 -o %OUTPUTDIR%TaiwanS.osm %SRTM% -bounds1 23.59 120 25.4 122.1 -o %OUTPUTDIR%TaiwanN.osm TaiwanS mearures 1554993 kB, TaiwanN 2249418 kB (I must do it in 2 parts, otherwise the program uses more than 7 GB of RAM and causes lots of paging). Next, I sorted one of the files with osmosis (originally I sorted and merged both of them, and then merged with an extract from Geofabrik; that's what I plan to do when I got things working...): SET OSMOSIS="C:\Program Files (x86)\OpenStreetMap\osmosis-0.46\bin\osmosis.bat" SET INPUTDIR=E:\Maps\Raw\Taiwan.DEM\ %OSMOSIS% --read-xml %INPUTDIR%TaiwanS.osm --sort --write-pbf %INPUTDIR%Taiwan_Ele.osm.pbf The output file measures 16670 kB. Next, I split it with SET JAVA="C:\Program Files\Java\jre1.8.0_121\bin\java.exe" SET SPLITTER="C:\Program Files (x86)\OpenStreetMap\splitter-r590\splitter.jar" SET INPUTDIR=E:\Maps\Raw\Taiwan.DEM\ SET INPUTDATA=Taiwan_Ele.osm.pbf SET NAME="BernieMap Bike Taiwan" %JAVA% -Xmx6G -jar %SPLITTER% ^ %INPUTDIR%\%INPUTDATA% ^ --description=%NAME% ^ --max-nodes=2500000 ^ --no-trim ^ --mapid=47120001 ^ --max-threads=4 ^ --keep-complete=true which creates 3 pbf-files. Finally, I build the map with SET JAVA="C:\Program Files\Java\jre1.8.0_121\bin\java.exe" SET MKGMAP="C:\Program Files (x86)\OpenStreetMap\mkgmap-r4107\mkgmap.jar" SET PREPROC=E:\Data\Projects\Projects.Net2\StylePreProcessor\bin\Debug\StylePreProcessor.exe SET STYLE=E:\Maps\Development\Style.Mapnik\Mapnik.Bike SET DEMPATH=E:\Maps\Raw\Taiwan.DEM SET NAME="BernieMap Bike Taiwan" SET TYP=M04712.TYP %PREPROC% /in=E:\Maps\Development\Style.Mapnik\Mapnik.Base /out=%STYLE% /defines=BIKE,THAI copy E:\Maps\Development\Style.Mapnik\%TYP% %TYP% copy "C:\Program Files (x86)\OpenStreetMap\GMT\gmt.exe" gmt.exe gmt.exe -wy 4712 %TYP% %JAVA% -Xmx6G -ea -jar %MKGMAP% ^ --style-file=%STYLE% ^ --family-name=BernieMapTaiwan ^ --family-id=04712 ^ --product-id=1 ^ --description=%NAME% ^ --series-name=%NAME% ^ --name-tag-list=name:en,int_name,name ^ --latin1 ^ --add-pois-to-areas ^ --route ^ --location-autofill=bounds,nearest ^ --preserve-element-order ^ --draw-priority=25 ^ --index ^ --nsis ^ --show-profiles=1 ^ --generate-sea=multipolygon,extend-sea-sectors,floodblocker ^ --max-jobs=4 ^ --dem-poly=areas.poly ^ --x-dem=%DEMPATH% ^ --x-dem-dists=3314,4000,6000,8000,10000,15000,20000,30000 ^ --gmapsupp 4*.osm.pbf ^ %TYP% move gmapsupp.img E:\Maps\Use\Taiwan.IMG which creates an IMG file of 18798 kB. It is recognized by my Oregon 600. In the demo mode, I navigate to a waypoint (Luigui, 22.99573 N, 120.63496 E). I expect to see a map of contourlines only. But I get a completely white map. Elevation from DEM is 250m directly adjacent to the waypoint, and other sensible values nearby. The style file contains: contour=elevation & contour_ext=elevation_major & (ele > 0 | ele < 0) { name '${ele|conv:m=>ft}'; } [0x20 level 4] contour=elevation & contour_ext=elevation_medium & (ele > 0 | ele < 0) { name '${ele|conv:m=>ft}'; } [0x21 level 2] contour=elevation & contour_ext=elevation_minor & (ele > 0 | ele < 0) { name '${ele|conv:m=>ft}'; } [0x22 level 0] The TYP file (created and compiled with MapTk) contains: [Polyline] Type=0x20 String=0,Höhenlinie String=4,Elevation Color=0,0x000000 Line=00..00 [END] [Polyline] Type=0x21 String=0,Höhenlinie String=4,Elevation Linewidth=1 Color=0,0x000000 [END] [Polyline] Type=0x22 String=0,Höhenlinie String=4,Elevation Linewidth=2 Color=0,0x000000 [END] which should cause black elevation contour lines. What do I do wrong? Thanks a lot for your hints. Kind regards, Bernhard

—route & —transparent options
by David 15 Feb '18

Hello, Transparency is not used only with contour lines. In my case, I use these two options for my OpenStreetMap layer and it works on BaseCamp and my Garmin Oregon 650 (and also on my old Etrex few years ago). David PS: if you wonder what layers are, see http://emerald-island.eu/wikka/GpsMap
