RIK maps

Alternative 1 (easier, works mostly, gives more map slices)

  1. Use ShapeUp orGDAL to convert from RIK to jpg.
  2. Rename the extensions, jpeg to jpg and tfw to jgw, for OziExplorer to be able to find the files.
  3. Import the converted file(s) as DRG maps in OziExplorer. Ozi will create map-files for each jpg-file.
    • Map Datum = RT 90
    • Map Projection = Swedish Grid
  4. Convert all maps using OruxMapsDesktop, use RT90:Swedish and UTM. To be able to do this in a batch (while so many map tiles are created) do as follow:
    • add “RT 90|RT90Swedish” to the file Ozi2Orux.txt in the OruxMapsDesktop install directory.
    • in all created map-files, change “(SG) Swedish Grid” to “(UTM) Universal Transverse Mercator”, this because the batch converter in OruxMapsDesktop currently do not support Swedish grid.

Alternative 2 (lots of work)

  1. Use ShapeUp orGDAL to convert from RIK to jpg.
  2. Rename the extensions, jpeg to jpg and tfw to jgw, for OziExplorer to be able to find the files.
  3. Import the converted file(s) as DRG maps in OziExplorer. Ozi will create map-files for each jpg-file.
  4. The projection of the map is at 2010-07-30 one not supported by OruxMaps (WGS84, RT90 or SWEREF 99, with projection swedish grid), check at OruxMaps homepage if this has changed.
  5. If the projection is not supported you need to convert the map.
    1. Use Img2Ozf or MapMerge to convert to WGS84 and UTM zone 33. Remember to use the same pixelscale as original map.
    2. The converted map will be of ozfx3 type, which is not supported by OruxMapsDesktop, use DeMapper to create jpg maps.
  6. Now you have a map in a format and with projection supported by OruxMapsDesktop.

Alternative 3

1. Öppna rik-kartan i Global Mapper och ändra i inställningar så att den visas i UTM zone 33 och WGS84.
2. Spara som jpg och välj att dela upp den i bitar t.ex. 5000*5000px med en överlapp på 250px.
3. Döp om alla .jgw till .tfw med Ant Renamer.
4. Kör OruxMapsDesktops batch converter och specificera UTM zone 33 och WGS84.

Alternative 4

Use Global Mapper to convert RIK to png file with OziExplorer map-file.
Be sure to set UTM zone 33 and WGS84 for the RIK map first.
Convert the OziExplorer map to Oruxmaps map using MAPC2MAPC.

Alternative 5

Use MAPC2MAPC with GDAL to open the RIK map and convert it to Oruxmaps format.
