Change Base Maps

This function allows you to update all the old digital maps in your map folder. You can also switch layers (from analyses, territory organizations etc.) to a different territorial structure without losing all settings or having to recreate the analyses.

Choose new Base Map

If you call the command base maps change, you will first get an overview table that lists all base maps used in the workbook. Here you can specify for each base map used which new base map is to be switched to. Initially, the entries for "old base map" and "new base map" are the same. If you do not change the setting under new base map, the old base map is kept.

  • For base maps in LTG format you can use the comfort function Automatic search. easymap searches in the same directory where the old base map is located for the latest version compatible to this base map.
  • To select the specific new base map, click in the cell under new base map of the map you want to change and click the button with the three dots to open the new window select base map.

When you have made all assignments between old and new base maps, click Ok to start the switching. The result is then displayed in the change log.


  • Not only the base maps of layers are changed, but also the basic building blocks of territory structures. (You can also do this individually for a territory level via the command Change brick level)
  • All layers of a base map are always updated to the new version. It is not possible to exchange only one layer via this function (apart from the above mentioned function to reassign an area structure to a new base).
  • The action cannot be undone. If you want to archive the previous state, make a backup copy of the EMPX file beforehand.
  • There are cases where the basis cannot be changed (see section Change log of the action change base map).
