I understand how to work with DEM's that I get from this website http://datagateway.nrcs.usda.gov/ and what I mean by working with them is generating contours from the DEM's and coloring the elevations. However Kentucky puts out information as found here http://kymartian.ky.gov/ which is older information, and new information is found here
Are you able to help or direct me to a blog post that can work with the second set of information. Below is a list a copy of an email that lead me to the information found at the KYRASTER.KY.GOV site.
I have talked to you a few random times on the phone before and was wondering now if you could tell me when the DEM data and aerial photo data for project area #2 as mentioned here http://kygeonet.ky.gov/kyfromabove/ is available for download yet?

There was no aerial photography acquired for Project Area #2. We only captured LiDAR in that area. About 1/3 of the DEM is complete for the area and it can be accessed from this URL. The remaining elevation data has been captured but it is still being processed.
Thanks Kent! I am now wondering if there is a way that I can download this DEM data so that I can use in Autocad.

Currently, you can clip out a maximum size of 20K x 20K from the image service using ArcMap. 5K tiled DEMS will be available for download by the middle of the year.
My basic question is can I do anything with the DEM that Kent is talking about currently in autocad, meaning generate contours, or do I need to wait for the downloads to become available? Any thoughts?
Solved! Go to Solution.
Anybody got any thoughts? Is the answer to my question, can I only view data as static image when attached to it as a WMS, with no hope of "working" with the data?
A WMS service is projected in view-only mode, i.e. you cannot download anything from there, because it simply generates "on-the-fly" screen answers to your queries.
