Switch the Data Set in PC*Miler Connect

Depending on the types of PC*Miler data add-ons you have licensed, you may have access through PC*Miler Connect to multiple sets of routing data, including street-level data in North America and worldwide highway data (PC*Miler Worldwide).

The data set currently in use is identified in your C:\ALK Technologies\PCMILERxx\App\user.cfg file in the [Directories] section. “Base” indicates the North America data set first released with that version of PC*Miler.
