Okay it took me two really long days of programming, reverse engineering and data mining but I was able to sleuth out the data I needed from DontKnowFoo's Sanborn2.KML overlay that contained reported MTurk HITs.
At this point in time the entire Sanborn2 0909-10400 series (10400-10499) and most of the known Sanborn2 0909-10500 series (10500-10567) of imagery is now accessible via my KML overlay generator. The exceptions are the image sets 0909-10553 and 0909-10566. I know all of the file names for images that exist for 0909-10553, but I do not have any coordinate data for this image set. I have not been able to find any images in the 0909-10566 series so I don't know if this imagery exists on Amazon's servers.
As much as many of us (myself included) have griped about people reporting every strange rock, tree, sagebrush and car as a possible sighting, we have the thousands of false reports to thank for our ability to gain access to the 0909-10500 series of imagery. If it weren't for the thousands of false reports, contained in the Sanborn2.KML overlay, I would not have had all of the coordinate data I needed to be able gain access to the 10500 series of imagery.
My efforts to provide access to the 0909-10500 series of imagery did require some retooling of my KML generator to accommodate lots of file naming inconsistancies in the 0909-10500 series of imagery, so please report any issues that crop up.
My next two tasks will be to allow people to request overlays using DMS coordinates in addition to decimal degree coordinates and to build a master boundary overlay for what is known of the Sanborn 2 imagery. I would also like to try and figure out some coordinate data for the 0909-10553 imagery.
