I am conducting research in a region of Illinois that does not have a LiDAR dataset. I am looking to develop a fine scale habitat species distribution model; however, the coarse data available (30m/10m) does not capture the microtopography of my study area. What recourse do I have in this situation? Can the 10m DEM be re-sampled perhaps to more accurately reflect the actual landscape? Should field surveys be employed in addition to re-sampling?

    Are you aware the Illinois Height Modernization project? Apparently, they have LiDAR data including DEMs with resolution <1 meter for many counties. See here. – Andre Silva Apr 23 '16 at 21:36

    @AndreSilva Your comments would make a nice answer;) – Aaron Apr 24 '16 at 5:56

What recourse do I have in this situation?

Acquire/integrate data with finer resolution.

Can the 10m DEM be re-sampled perhaps to more accurately reflect the actual landscape?

No, it can't. At least without inputting additional data.

Should field surveys be employed in addition to re-sampling?

It is an alternative.


Alternatively, are you aware of the Illinois Height Modernization project? Apparently, they have LiDAR data including DEMs with resolution <1 meter for many counties. See here.
