Extract by Mask is similar to setting the Mask option in the environment, except that the mask used in Extract by 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. When a multiband raster is specified as input, a new multiband raster will be created as output.
How does the extract by Mask tool work? The Extract by Mask tool is similar to 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. When a multiband raster is specified as input, a new multiband raster will be created as output.
What is the difference between clip and extract by mask? Md. Mokshedur Rahman Both Clip and Extract by mask are basically the same; however, Extract by mask will change the pixel values based on the two input raster data, while the Clip toolbox will clip the raster input without changing the digital numbers or the gray values. I think both are same, but mask will influence your raster value.
What is input mask data? The input mask data defining the cell locations to extract. It can be a raster or a feature dataset. When the input mask data is a raster, NoData cells on the mask will be assigned NoData values on the output raster.
What happens if mask is specified in the environment setting? If Mask is specified in the environment setting while running the Extract by Mask tool, the output raster will have cell values only for the area that lies within the intersection of the environment mask and the input mask data.

How do I convert a mask input to a raster? If the mask input is a feature, it will be converted to a raster internally, using the cell size and cell alignment from the Input raster.
How to extract a raster using ArcGIS? Extract by Mask using ArcGIS. It is possible to select a specific area of a raster using another layer (raster or entity) as a template whose extension delimits the extent of the output raster. The output raster will maintain its attribute table, bounded to the extension that we have imposed.
What happens when 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.
How to exclude areas from raster processing in ArcGIS? Same with “Erase tool”, it does not accept my DEM. I’m using ArcMap 10.2.2. The best way to exclude areas from raster processing in ArcGIS is with the Mask Environment Setting. To use it, you will need a positive mask that covers the areas that you want to process, rather than a negative mask that covers the areas that you want to exclude.
How does the extract by Mask tool work?
What is the output raster of the input 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. When a multiband raster is specified for the input raster mask, only the first band will be used in the operation.
What tools can create the mask raster? Tools that can create the mask raster include Con, Test, and other tools in the extraction toolset. When a multiband raster is specified for the input raster mask, only the first band will be used in the operation. If the input raster is integer, the output raster will be integer.
What happens when 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.
What happens if mask is specified in the environment setting? If Mask is specified in the environment setting while running the Extract by Mask tool, the output raster will have cell values only for the area that lies within the intersection of the environment mask and the input mask data.
