Imaging system uses space technology

That funny looking vehicle roving around Columbia County during the next couple of weeks might look like something that belongs in space.


There’s a reason for that: The Earthmine mapping rig uses technology from NASA.


Columbia County’s Geographic Information Services Department brought in the Earthmine vehicle and its sophisticated camera systems two years ago to provide three-dimensional images of more than 1,100 miles of county roads and everything alongside them.


The Earthmine imaging vehicle is returning to update those images, said Mary Howard, the county’s GIS department manager.


“It’s the same technology that was used for mapping Mars. It’s pretty incredible,” said Howard. “It’s like Google Earth on steroids.”


The mapping vehicle, with sophisticated, 32-megapixel cameras mounted on top, will travel more than 1,200 miles of county roads. Rather than creep along, the vehicle travels at the speed limit to take panoramic, 360-degree photos every eight feet – even when traveling on Interstate 20.


Every photo is accompanied by precise measurements and geographic coordinates, Howard said. Once the data is compiled, it gives the GIS department three-dimensional images throughout the county that are used by multiple county agencies – for everything from measuring site distances for streets to inventorying fire hydrants. It also provides a timeline progression from the first set of Earthmine images snapped two years ago.


Production of those updated images will cost about $65,000, Howard said, but are well worth the expenditure.


The system already saved the county about $750,000 in disputed fees that would have been charged by the contractors installing the county’s broadband project, she said, because the mapping system provided evidence of how the miles of fiber-optic cable was installed.


It’s also expected to save the county money when combined with a street-light audit by Georgia Power that already has discovered the county being charged for lights in commercial parking lots.


“That will be even more cost-savings, too,” Howard said. “I think there are all kinds of uses I’m not even aware of.”

And Columbia County is fortunate to have Mrs. Mary Howard as this department manager. She is a highly skilled, well liked IT professional who has kept Columbia County on the technological cutting edge. Congrats. DD
