The Ohio Department of Transportation wants to spend nearly $2 million on a modified airplane for aerial mapping. Evne though at least three Ohio firms already provide this service. What’s even more disturbing is that the state, like every other state remains in a very tight fiscal situtation. The state wants to install remote-sensing equipment known as “light detection and ranging” — or LIDAR — to conduct three-dimensional mapping and surveying. The specialized craft would be used to plan and design highway projects and for environmental purposes. Again, this service has traditionally been provided by at least three Ohio private companies. The move by the DOT is an expansion of service and encroachment on commerical activities.
