MnDOT conducts aerial photography in Roseau and Warroad
Residents asked not to disturb temporary targets
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 Roseau and Warroad.
Aerial mapping will take place in the following locations:
- Highway 11, east of Roseau
- Highway 11, west of Warroad
- Highway 313, north of Warroad
Additionally, traditional survey crews will be working along Highway 11 west of Warroad. It is in anticipation of an unscheduled future project between 550th and 570th Avenues on Highway 11 west of Warroad. This two-mile section was part of the countywide Highway 11 corridor study completed last year.
Possible improvements include a center turn lane, additional right turn lanes and driveway access changes. Further details and renderings of the alternatives are available on the project website: www.dot.state.mn.us/d2/projects/hwy11assessment/warroad.html.
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 operations. “Crews paint large white ‘X’ targets on paved surfaces” said Dan Domeier, MnDOT Land Surveyor. “For unpaved locations they use a wood panel target.”
A survey crew then records the coordinate position and elevation of these targets, and provides that information to 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 2 survey staff at 218-755-6533 or by email at firstname.lastname@example.org.
