What happens when mask is specified in extract by mask?
If Mask is specified in the environment setting while executing the Extract by Mask tool, the output raster would have cell values only for the area that lies within the intersection of the environment mask and the input mask data.
How does extract by mask work in ArcGIS?
Extracts the cells of a raster that correspond to the areas defined by a mask. The result of using the Extract by Mask tool is similar to that of setting the Mask environment, except that the input mask is only used on the immediate instance, while a mask set in the environment is applied to all tools until it is changed or disabled.
What are the tools for extract by mask?
If the input mask is raster, the values for non-NoData input cell locations are copied to the output raster. Tools that can create the mask raster include Con, Test, and other tools in the extraction toolset.
How is the input mask data defined in raster?
Input mask data defining areas to extract. It can be a raster or feature dataset. When the input mask data is a raster, NoData cells on the mask will be assigned NoData values on the output raster. The output raster containing the cell values extracted from the input raster.
How to stop ArcGIS Desktop-avoiding extract by mask error?
The output raster needs to be saved in a file geodatabase instead of a normal folder. This will stop the unknown error: 999999 Simply write the file extension when selecting output location and renaming the output, for example: extract.tif (like the original DEM/raster extension name).
How to extract a mask from a raster?
Input mask data defining areas to extract. It can be a raster or feature dataset. When the input mask data is a raster, NoData cells on the mask will be assigned NoData values on the output raster.
How to extract cells from a mask in ArcGIS?
The output raster containing the cell values extracted from the input raster. This example extracts cells from a raster within a mask defined by an input polygon shapefile feature class. This example extracts cells from a raster within a mask defined by an input polygon shapefile feature class.
When is the input mask is feature data?
When the input mask is feature data, cells in the input raster whose center falls within the perimeter of the feature will be included in the output, while cells whose center falls outside it will receive NoData. The output raster containing the cell values extracted from the input raster.
