A forest map related to the stand register data can be imported ("Link to existing area..." or "Import forest map..." > "Import from shape") only if the format is "Shape". Digital maps in other formats should be converted before import. Linking is done by using the .dbf-file of the map and the three first fields of the register's .csv-file (MapId, StandId, and SubStandId, respectively).

Background images (in raster format, as opposed to the vector format above) can be imported and viewed with the forest map. Preferrably, the image should be in .tiff-file format (but other graphical formats are possible, e.g. .bmp). NB: Only one layer per type (Road-, Terrain-, and Ortomap) is possible to import to the forest database, any new image-import will overwrite the old, already imported images! This is of course unfortunate and will be fixed in future releases. A roadmap, more or less covering the entire company sphere of activities, might be imported once and for all while the ortophotos probably would be added continuously as new areas are to be analysed.

However, this is the somewhat advanced steps in importing images:

  1. In your GIS, open the raster image
  2. If necessary, zoom to/select the area of interest (to decrease the extent of the image and hence the file-size)
  3. Choose "Export Raster Data" (or similar)
  4. Now you might be in a tricky position; if the original image is in 8 bit you must force it into the three bands RGB to obtain a 24 bit-image. This might be possible only if you export to an output raster with .bmp-format.
  1. To change the folder where the project will be created, choose Browse (to the right of the Location combo box), and select a folder. The new project will be created in a sub folder in the selected folder . The sub folder will have the same name as the project.
  2. To specify or change the location of the forest database, choose Browse (to the right of the Forest Database combo box), and enter the database configuration for the forest database.
  3. To specify or change the location of the result database, choose Browse (to the right of the Result Database combo box), and enter the database configuration for the forest database.
  • Tip 1
You can quickly select one of the most recent project locations, forest databases, and result databases you have used by dropping down and selecting a value from the corresponding combo box.
  • Tip 2
To see more information, you can resize the open project dialog.
  • Tip 3
To create a


Associated pyramid file is used for geo-referencing. Any conversions - coordinate system transformations - should be done prior to import. [The map-viewer in PlanWise is based on the Swedish Grid (RT90, 2.5 gon V), redundant?]
