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)

Hello to everyone, i'm trying to apply this method Using Image Analysis Functions to Display Layer Tints on Hillshades | ArcWatch    to create an image that retains the original colors and details Using Image Analysis Functions to Display Layer Tints on Hillshades avoid a washed-out image with less detail.

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=" 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!

I am currently working on a small project which entails creating some flood senarios using newly current lidar data. However I have an issue with lidar data. The Lidar data which we have received contains reflections on the water surface so called specular reflections ( see attatchment beneath) which cause the water surface to have elevations… (Show more)
Hi all,   I'm exporting data (using Creating LiDAR-Based Heightmaps in Unity 3D (Using ArcGIS) - YouTube ) for guidance.   I've imported in LAS data as a LAS dataset, then am using some of the filtered ground points and the tools "LAS Dataset to Raster" (found through the search feature in the right pane) to rasterize filtered ground points and… (Show more)
