Option A: Use Raster Calculator. In ArcMap, navigate to ArcToolbox > Spatial Analyst Tools > Map Algebra > Raster Calculator. In the Raster Calculator window, double-click one of the rasters to be analysed, click the minus sign (-), and double-click the second raster. Specify the name and location for the output raster.
How does select layer by location work in ArcMap?
Select Layer By Location allows you to change the set of selected features in ArcMap by finding features in one layer that are within a given distance of (or share one of several other spatial relationships with) features in another feature class or layer. Unlike the other vector tools, Select By Location does not create new features or attributes.
What is the name of the buffer field in ArcGIS?
The name of the field in the output feature class that stores the buffer distance used to create each buffer feature. If no name is specified, the default field name is ‘distance’. This field will be of type Double.
How to dissolve multiple ring buffers in ArcGIS?
If the Dissolve Option ALL is used, the output feature class will contain one feature for each distance specified in the Distances parameter (all buffers the same distance from the Input Features will be dissolved). The tool creates intermediate data which is written to the location specified in the Scratch_workspace environment setting.
How does the eliminate tool in ArcGIS work?
The Eliminate tool combines selected polygons, often splinter polygons that are smaller than a given size (usually, splinter polygons are caused by overlay of slightly discrepant datasets), with adjacent polygons to remove spurious polygons from the dataset.
How can I create a shape file from an existing shape file?
There are two methods you can use. One is to select a portion of an existing shape file and export that to a new shape file. The other is to clip an existing shape file by using another polygon shape file (like using a cookie cutter) to create a new shape file.
