MnDOT conducting aerial photography work in southwest Minnesota

WILLMAR, Minn. – The Minnesota Department of Transportation will conduct aerial mapping in southwest Minnesota this spring. The mapping will create a record of existing infrastructure and landscape along, and adjacent to, MnDOT right of way for transportation planning and highway design. This work will be conducted after the snow has melted and before trees leaf out.

Weather permitting, work will begin early-April and conclude mid-May at the following locations:

  • Highway 23 – from Lyon County Road 7 to 300th Street in Marshall
  • Highway 19 – from Laser Avenue in Redwood Falls to Renville County Road 15 near Morton
  • Highway 12 and Highway 15 – one-half mile in each direction of the intersection in Dassel

The public is asked to not disturb temporary targets
In order to obtain accurate aerial mapping, MnDOT crews paint large white “X” targets on paved surfaces, and place plastic or fabric “X” targets on unpaved surfaces. Examples of the types of targets that may be used are attached.

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

Landowners in the areas that will have targets placed on or near their property will be contacted directly. MnDOT asks that landowners and others who come across targets not remove or disturb the targets. If a target must be moved, please contact the District 8 Willmar Office at 320-231-5195 and ask for assistance from Surveys.
