Where do I find min and max values in raster?
If a Raster* object is created from a file on disk, the min and max values are often not known (depending on the file format). You can use setMinMax to set them in the Raster* object.
Can a raster calculator be used in ModelBuilder?
The Raster Calculator tool can be used in ModelBuilder, but keep the following points in mind: The syntax of the expression determines how variables are to be specified. If you select a variable from the variable list, it will be automatically added to the expression at the current cursor location.
What are the operators in raster calculator in Python?

The operators in the Raster Calculator tool dialog box are: Multiple geoprocessing tools and operations can be combined in a map algebra expression using standard Python syntax. When typing tool names, be sure to check the tool name syntax.
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 to find a MAX cell value from a stacked raster?
How can I find a max cell value from a stacked raster. gives NA. Of course not in a stacked raster. The following example shows two ways to get at the max raster value in a stack. The first utilizes max () which also gives you a host of other useful information.
How to sum the layers of a rasterstack?
Each file (corresponding to a year) is a RasterStack element with the following characteristics: each layer is the raster of values of a day. I would like to sum the layers in order to calculate the monthly values.
How do you create rasterstack object in R?
The second part of the code t.mean <- stack (t.mean.files) creates the RasterStack object from the list of files in “t.mean.files”. If you were to take a look at the “t.mean” object in the R console, you would see it has an additional “dimension”, nlayers, with a value of 12.
