Digitized Floodplain Maps: A Sensible Idea?

[Allen] county will spend $700,000 over the next five years to create a new digital floodplain mapping system that will aid work on drainage engineering, zoning, economic development, homeland security and floodplain management…

When complete, the maps will be accurate within inches, Degen said. Current county maps that are decades old are not correct.

“The existing maps are of very poor quality, but it was the best information available at the time,” Degen said. “If we didn’t do this, FEMA was going to take our old maps, digitize them and say, ‘Here are your new maps.’”

I wonder if Hamilton County has a high quality digitized geographical information system. It seems like a good idea to have a digitized map of the entire SW Ohio/N Ky/SE Indiana region. The counties could share the cost and each would have a map of the entire region, not just itself. It makes sense to have a regional map (rather that just a county map) for economic development and civil engineering projects.
