Raster Calculator in Spatial Analyst incorporates arithmetic operators, logical operators, Boolean connectors, and mathematical functions in a dialog box. Optionally, use Python to automate setting NoData values to other values. The examples are shown below.īelow is an example of the statement to convert the NoData values to 0 for the Raster Calculator in 9.3:īelow is an example of the statement to convert the NoData values to 0 for the Raster Calculator in 10.x: However the Raster Calculator may also be used to call the Con and IsNull tools to perform the same task. In both versions 10.x and 9.3, the Con tool can be used outside of the Raster Calculator to create a new raster with reset NoData (Null) values. Alternatively, use the Raster Calculator tool to call the Con and IsNull tools to use them to change NoData values to other values. Refer to ArcMap: How to change NoData cells to a value for more information. One option is to use the Con tool in conjuction with the IsNull tool from the Spatial Analyst toolbox to convert NoData values. Since NoData cells are ignored in any analysis, such requirements can only be met if those cells have a specific value assigned to them.ĪrcGIS offers a couple options to convert NoData values to another constant, such as zero. Various spatial analysis applications require raster NoData cells to be factored into an analytical operation. ![]() ![]() How To: Convert NoData values to other values for raster data Summary ![]()
