Is there a way to iterate raster names in ModelBuilder?

Is there a way to iterate raster names in ModelBuilder?

I believe ModelBuilder, using the “Iterate Rasters” tool and the “Raster Calculator” tool, should do this. In “Raster Calculator” outside of modelbuilder, selecting the raster name and typing + 1 works to do this on a single raster. However, in modelbuilder, using (“%Raster%”) + 1 does not work (see attached photo).

How are variables connected to the raster calculator?

Variables are connected to the Raster Calculator tool when they are selected from the list of variables. All variables are automatically listed in the Variable list inside the tool. When a dataset or variable is used in the expression, a link between the variable and the tool will be created.

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.

Where can I iterate over rasters in Python?

Iterates over rasters in a Workspace or a Raster Catalog. This tool is intended for use in ModelBuilder and not in Python scripting.

How to calculate the log of a raster?

One of the final steps is to calculate the log of one of the rasters using Raster calculator. Unfortunately, I get the error at that last final step: ERROR 000539: Error running expression: rcexec () Traceback (most recent call last): File “”, line 1, in File “”, line 5, in rcexec TypeError: cannot concatenate ‘str’ and ‘int’ objects

How to use raster calculator in ArcGIS 10?

Note, the value of the element can have percent signs in it, but the element name/label cannot have percent signs. A dotted line means the output is acting as a precondition to the tool. So in your model f%value%_D must exist (thus the Euclidean Distance tool ran without error) before the Raster calculator can execute.

How to use a dotted line in a raster calculator?

A dotted line means the output is acting as a precondition to the tool. So in your model f%value%_D must exist (thus the Euclidean Distance tool ran without error) before the Raster calculator can execute. Your Raster calculator expression is Ln (“%f%value%_D%” + 1).

How are iterators used in the ModelBuilder tool?

In this case, iteration has been restricted with a wildcard A* and raster type of GRID so that it only iterates over rasters starting with the letter A and only on grids. The tool has two outputs: Output Raster variable (Aland, Aparcel, and Aroad) connected as input to the Resample tool.

How to iterate through rasters in ArcGIS Pro?

Workspace containing the rasters to iterate through. A combination of * and characters that help to limit the results. The asterisk is the same as saying ALL. If no wildcard is specified, all inputs will be returned.

Where are rasters stored in ArcGIS ModelBuilder?

In the image below, the model creates a mosaic using rasters stored in a geodatabase named Arizona, which is stored inside a folder. The iteration has been restricted with the wildcard Ar* and workspace type of file geodatabase so that it only iterates over file geodatabases with names starting with the letters Ar.

Is it possible to use the raster calculator outside of Spatial Analyst?

Is it possible to use the raster calculator outside of the Spatial Analyst drop down menu? Check out the Single_Output_Map_Algebra ‘>Single Map Algebra Output Tool in Spatial Analyst Toolbox > Map Algebra Toolset. It can be used in ModelBuilder.

Why are raster datasets displayed as solid black?

It is also possible to have this problem with raster datasets within a raster catalog; they may also appear as solid black when displayed in ArcGIS Desktop. This can be caused by missing raster statistics.

Is there a tool to iterate over rasters in Python?

Iterates over rasters in a workspace. This tool is intended for use in ModelBuilder, not in Python scripting. The tool has two outputs: Raster and Name, which could be used as inline variable %Name% in other tools. Workspace containing the rasters to iterate through.

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.

Do you need to cast input data as a raster object?

The only differences are the following: You do not need to put the output raster name or the = sign in the expression because the output name is specified in the Output raster parameter. You do not need to cast input data as a Raster object when using operators.
