Symbolizing the highway routes with hatch marks is a useful method of posting measurement or distances along a route. To assign hatching symbology at 2 kilometre intervals an ArcGIS Version 10.2.2 symbology layer file has been created. It can be imported into the feature class when assigning symbology in an ArcGIS map file. The layer file name is NWTHighways2kmHatching_V10_2_2.lyr. It is a useful file to have due to the requirement for VBScript when labeling the hatches. If you would like a copy of this file please contact the NWT Centre for Geomatics.
