BEMIDJI, Minn. – In a sure sign of spring, the Minnesota Department of Transportation begins its transition away from snowplow operations by conducting aerial mapping in west central Minnesota.

Aerial mapping will take place in the following locations:

  • Highway 28 between Highway 59 and Starbuck
  • Highway 34 from Osage to Park Rapids
  • Highway 75 between Wheaton and Highway 55
  • Highway 92 between Clearwater County Road 35 to Highway 200 at Zerkel
  • Highway 200 between Highway 71 and Clearwater County Road 2 at Itasca State Park
  • Interstate 94 between Evansville and the north Grant County line

The aerial survey process relies on clear observations, and must be conducted after the snow has melted and before the trees leaf out. To begin the process crews place an “X” on the ground as a reference point for the aerial photographer. Weather permitting; work will begin next week.

The mapping will create a record of existing infrastructure and landscape along MnDOT right of way for transportation planning and highway design. In order to obtain accurate aerial mapping, MnDOT crews will paint large white “X” targets on paved surfaces, and place plastic or fabric “X” targets on unpaved surfaces.

A survey crew then records the coordinate position and elevation of the temporary targets for the aerial photography company. The wood panel targets are temporary and will be removed when the photography is completed.

MnDOT requests that landowners not remove or disturb the targets until the photography is completed. If a target must be moved, please contact MnDOT District 4 survey office at 218-332-5644 or by email at
