BEMIDJI, Minn. – In a sure sign of spring, the Minnesota Department of Transportation begins its transition away from snowplow operations by conducting aerial mapping of several locations in northern Minnesota.
This 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 in early April in the following locations:
· Red Lake- Highway 1
· East Grand Forks- Highway 2
· Bemidji- Highway 2 and Highway 71
· Hallock- Highway 75
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.
