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.
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.
Is there a way to extract cells from a raster?
Available with Spatial Analyst license. Extracts the cells of a raster that correspond to the areas defined by a mask.
When to use a multiband raster in ArcGIS?
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. If the input is floating point, the output will be floating point.
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 are masking features handled in ArcGIS Pro?
Layer masking—A layer of features or masking layer masks any overlapping features of another layer in the map or scene. Feature-level masking—Masking is handled for each feature as specified by a relationship class between two layers. With both ways of masking, the geometry of the masking features masks the symbology of the masked features.
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 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).
Why do I get error extract by mask?
I am iterating through ~300 raster tiles, using a polygon feature class to extract by mask. The model successfully processes the first ~100 tiles and then I get the following error on the same tile each time: ERROR 999999: Error executing function.
How to create a raster by mask in ArcGIS?
You could also use the Raster Calculator to create a Mask raster using operations like AND/OR (something like “raster1 == 255” | “raster2 == 255” assuming that white = 255 in your screenshots) Once you have this sorted you should be able to perform an Extract By Mask using the new raster with NoData values as a mask.
How to assign white cells to the raster mask?
If they are not properly labelled already, you could assign the white cells to the raster mask. That can be achieved for example by using the Copy Raster tool to modify the NoData Value.
How to extract based on a polygon in ArcGIS?
To extract based on a polygon in a feature class instead of providing a series of x,y pairs, you can use the Extract By Mask tool. The center of the cell is used to determine whether a cell is inside or outside a polygon.
How to exclude areas from raster processing in ArcGIS?
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 to create a mask in ArcGIS Spatial Analyst?
There are a number of ways to create a mask raster using various ArcGIS Spatial Analyst tools. In the extraction tool, as demonstrated in the image below, those locations that are not NoData in a mask raster will retain the value assigned to that location in the Input raster. A feature dataset can be used for the mask.
How to extract data from raster in ArcGIS?
ExtractByAttributes (in_raster, where_clause) Parameter. Explanation. Data Type. in_raster. The input raster from which cells will be extracted. Raster Layer. where_clause. A logical expression that selects a subset of raster cells.
