  1. Can someone help me out with computing the Mean Annual Precipitation values for a basin being modeled using the USGS NSS equations? The particular basins I'm modeling are in California in the South Coast Region, so I need to compute the Drainage Area (DRNAREA) and Mean Annual Precipitation (PRECIP) values for the equations. What type of GIS data do I need to have WMS compute and populate the PRECIP field? Gridded? Shapefile? I can use the beta of the USGS NSS web app to compute the Avg Annual Precip but I'd rather do it in WMS, because the current USGS web app does not go as far as actually
  2. Thanks Chris, The Data is from an Aerial survey. It is in the form of a comma delimited text file (X,Y,Z) and the elevations are taken on a grid at 5 foot intervals. I've been importing the text file as "survey data" which is basically the same as "tin vertices," if I'm not mistaken. Then I've clipped it down, but the area covered is around 300 acres of the LA River floodplain in downtown Los Angeles, and there is just too must data. I'd like to figure out some way to thin out the points in the flood plain, but retain the points near the river because it is the best resolution I'm going t
  3. Does any one have any tips on how I can increase the memory available to WMS. I'm working with large elevation dataset and while doing things such as building tins, reading in text files (high resolution aerial survey xyz files), delineating floods, etc. I am routinely getting an "Out of Memory" error that forces me to stop what I'm doing, close WMS and open it back up. Usually I can not even save my progress because I get the out of memory error when I try to save as well. My desktop configuration is as follows: Core 2 Duo 2.66GHz E6750 CPU 3.00 GB RAM 32-bit Windows XP Profess
