I'm looking for some insights into the accuracy (x,y,z) of oblique imagery from Pictometry in terms of providing accurate measurements for property evaluation. Is the high cost of this product justified by its potential to provide not only high visual/pixel resolution, but also highly accurate measurements? Essentially, I'm curious about alternatives that are more cost effective and provide equal or better accuracy in the 2-D plane.
I find a lot of sales/marketing info from Pictometry, but not much quantitative metadata in terms of consistency for what DTMs they use to rectify the images. There seems to be a lot of momentum behind this company and I want to know if it's justified.
