What does the raster Calculator do?
The Raster Calculator tool allows you to create and execute a Map Algebra expression that will output a raster. Use the Rasters list to select the datasets and variables to use in the expression.
What is raster compression?
About compression. Compression is specified when you create a raster dataset or load a raster dataset into your geodatabase. The primary benefit of compressing your data is to reduce the size of the file to help save disk space.
What is raster data compression?
When storing data in the geodatabase, the blocks of data are compressed before they are stored. Data compression can be lossy (JPEG and JPEG 2000) or lossless (LZ77, PackBits, CCITT). Lossless compression means that the values of cells in the raster dataset are not changed or lost.
Can a raster calculator be used in a compression environment?
Certain Raster storage environments may apply to this tool when output is in a raster format other than Esri Grid. For the Raster Statistics environments, only the Calculate Statistics check box is supported. For the Compression environments, only the type of Compression is supported.
How does a raster calculator work in ArcGIS Pro?
When the tool is executed, the resulting raster output will be clipped based on the specified extent. To create a raster with cells of a constant value, specify the appropriate extent and cell size environment settings and enter the numerical value into the expression.
Can you rename a variable in a raster calculator?
You should not rename a variable that is connected to the tool, since the variable will not be renamed within the expression. If you do so, the expression will be invalid. Certain Raster storage environments may apply to this tool when output is in a raster format other than Esri Grid.
How to create a raster with a constant value?
To create a raster with cells of a constant value, specify the appropriate extent and cell size environment settings and enter the numerical value into the expression. When multiple operators are used in an expression, they are not necessarily executed in left-to-right order.
