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.

Hey Kent,
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?
EMAIL :1 REPLY
Jon,
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.
Best Regards,
Kent

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.
Solved by antoniovinci. 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.
