Barrier base maps

Barrier files with the file extension *.bar.ltg contain information about areas that represent traffic obstacles, such as mountains, river sections without bridges or bays.

EasyMap normally uses linear distances for all distance calculations. However, depending on the topographical situation, these distances deviate greatly from the actual distances of the traffic routes. When planning an area, it can be crucial to cut areas so that all areas of the area are easily accessible.

Therefore EasyMap offers the consideration of barriers for the following situations:

• Territory Optimization: Consider barriers for area layout (Further information: hier)
• Analyses of territory organization: Consider barriers when calculating the values (Further information: here)

Barrier files are only available for map bases in LTG format (only for certain maps of Germany, Austria and Switzerland). The use of such a map base automatically determines which barrier file is used.

If you want to see which barriers a barrier file contains, you can display the barriers:

• Select Extras > Options from the menu and display General the Advanced settings tab. In the Advanced section, set the List Barrier Map Basics option to yes.

The map bases list will now be updated. Under Other you will find the available barrier files. You can now drag&drop the layers into a map to display their contents.
