I need to extract building footprints from a raster to a DEM using the raster calculator. The footprints will be used to improve a visibility analysis by providing obstacles/obstructions. The footprints have elevation data associated with them already. I'm fairly new to Python and I was hoping someone would be able to let me know of an expression… (Show more)

A co-worker was converting a binary raster using Float to Raster Tool and with header specifying XLLCORNER, YLLCORNER corner of image, he assumed data had to be written out in row major format from SW to NW, but that flipped the raster.  Why specify SW corner of data in header if data is written from NW.  Is this from some past convention that… (Show more)

Hi, I finally managed to create DEM from bathymetry points and calculate the volume, but the output does not make sense. I guess I need to modify the units or coordinates. I don't know how. Here is the output (My input surface is the elevations of the bed in meters above sea level (m asl) in GCS_WGS_1984 and decimal degrees and my Plane Height is… (Show more)

I am trying to use the Ground Surface Elevation 30m (href="http://goto.arcgisonline.com/elevation/NED30m) data to do some local processing. I wanted to extract an area and then work with it. But no matter what I do the raster calculator fails with nothing in the output raster. I have checked my environments, I am using a mask, projections are all… (Show more)

Hello everybody!   I'm making a map based on raster images that shows the highest points within certain areas. I've done Zonal Statistics and found the correct pixels but, they're teenie tiny, and I was curious if there was a trick with Symbology or pixel sizing that would make them more noticeable.   Thanks!
