I agree that if you are correct in your surmise about building heights, it could seriously limit usefulness of the DEM in many urban areas.Map Monkeyhttps://www.blogger.com/profile/03799927167426727749noreply@blogger.comtag:blogger.com,1999:blog-2582124947210486019.post-61162911630147690572011-10-25T18:00:26.906-04:002011-10-25T18:00:26.906-04:00ok i just finished downloading the data for NYC, a...ok i just finished downloading the data for NYC, and i'm getting some pixel values that are way different than the regular old DEM i was using. i just wrote them asking if this is because their measurement instrument picks up building height, not just land surface values. this would account for some very strange values in lower manhattan. if this is the case, i'm not so happy about how useful this is for dense urban areas, at least for my purposes. will let you know what i find out though! thanks for posting!!who else?!noreply@blogger.com
