Find Bad Data Values. Sometimes a raster’s metadata will tell us the range of expected values for a raster. Values outside of this range are suspect and we need to consider that when we analyze the data. Sometimes, we need to use some common sense and scientific insight as we examine the data - just as we would for field data to identify questionable values. Plotting data with appropriate...
Elevation data (DEM) is also distributed as raster files. In these raster files, the parameter that is being represented is encoded as the pixel values of the raster. Often, one needs to extract the pixel values at certain locations or aggregate them over some area. This functionality is …

  • service and export our AOI (area of interest) for local processing. With a local copy of the data we can proceed with reclassifying the dataset and analyzing our results for locating a potential site for our project. This tutorial consists of two methods for reclassifying raster datasets; the first of which requires Spatial Analyst extension, the second method utilizes the Image Analysis
  • If stripes or bleeding occur in the output raster, use the Check Geometry and Repair Geometry tools to correct the input feature data. When converting overlapping polygons, you may want the polygons with the smallest area to be assigned to a cell.
