It has been four years since ortho-photograhy has been taken on behalf of Ottawa County. Last time, it was black and white 6-inch pixel (a maximum resolution of 1'=50" on a paper map) taken with a traditional film camera. This time, we are purchasing color photos obtained through a digital camera. While the film camera required thousands of individual snapshots to cover a County our size (about 600 square miles), the digital camera uses a "push-broom" method. The equivalent of one giant exposure is taken with each sweep of the plane over land. Our County should be covered in about 25 sweeps. The technical specs of the equipment utilized by the company taking the photos is listed here. The photos were planned to be taken today.
For our part here on the homefront, we have made a minor attempt to immortalize ourselves through the air with sidewalk chalk (sample photo above). So, hopefully, our sketches will show up in the photos. I'm not sure if it will be successful. We'll see in a few weeks possibly. Then, I'll update.
