SUNBURG – Travelers in west central Minnesota might see large white “X” locator marks on roads in the region. The marks are part of an aerial mapping project by the Minnesota Department of Transportation that gets underway this week in six counties, including Swift and Pope counties.

Aerial mapping is used to create a record of existing infrastructure and landscape along MnDOT right of way for transportation planning and highway design.

MnDOT crews paint large white “X” targets on paved surfaces and place plastic or fabric “X” targets on unpaved surfaces as a reference point for the aerial photographer. The plastic and fabric targets are temporary and will be removed when the photography is completed.

Residents who see the marks are asked to not disturb the targets.

Aerial mapping will take place on state Highway 104 from state Highway 9 near Sunburg to Glenwood. Aerial survey crews will also be working in Douglas, Grant, Otter Tail and Traverse counties.

Letters have been mailed to affected landowners to further explain this process.

If a target must be moved, contact the MnDOt District 4 survey office at 218-332-5644 or by email at
