MDOT Mile Markers
收藏资源简介：
The Mile Marker Inventory contains mile marker location information along Michigan highways. Collection: The Mile Marker inventory was initially collected and completed in 2011 as part of the Lane Mile Inventory (LMI). Updates have since been made using roadway imagery. Data Quality: Data was collected to +/- 25ft accuracy using GPS in 2011. Similar results for more recent imagery updates are expected.
