How to use or in a con statement in the ArcGIS raster?
The pages Building expressions in Raster Calculator and Conditional evaluation with CON don’t help, and “or” seems to be keyword that Google ignores…. It is important to know the precedence level of the operators.
Can a con tool be used for multiple rasters?
The input of multiple rasters is possible since the Con tool is evaluated for each x,y cell location before moving to the next cell. When multiple rasters are input, the specified operator or tool will process on a cell-by-cell basis between the multiple rasters.
When to use multiple rasters in conditional statement?
Multiple rasters can be used in the conditional statement or in the expression to be performed on the cells. The input of multiple rasters is possible since the Con tool is evaluated for each x,y cell location before moving to the next cell.
Can a raster be an integer or a constant?
It can be an integer or a floating point raster, or a constant value. The input whose values will be used as the output cell values if the condition is false. It can be an integer or a floating point raster, or a constant value.
When to use a conditional expression in ArcGIS?
In the above expression, if the input value from InRas1 is greater than 5 and less than 10, assign the location to 5; otherwise, assign it to 100. Tools and operators can be applied to the input rasters in the conditional expression and the results evaluated.
When to use a constant in ArcGIS Pro?
If the conditional input is a multiband raster and the true or false raster input is a constant, the tool will perform the operation using the constant value for each band in the multiband input. If the evaluation of the expression is nonzero, it is treated as true.
How to do a conditional if or else in ArcGIS?
In this example, where the value of the input conditional raster is greater than or equal to 1500, the output value will be 1, and where it is less than 1500, the output value will be 0. # Name: Con_Ex_02.py # Description: Performs a conditional if/else evaluation # on each cell of an input raster.
Can you use spatial analyst in ArcGIS Pro?
Available with Spatial Analyst license. Available with Image Analyst license. Performs a conditional if/else evaluation on each of the input cells of an input raster. If either the true raster or the optional false raster is floating point, the output raster will be floating point.
What can you do with a raster calculator?
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.
How is conditional input raster used in Map Algebra?
A number of Spatial Analyst tools can be used to create a conditional input raster. In particular, the logical tools in the Math toolbox can be used, with the Test tool being particularly useful. To perform conditional evaluation on a raster dataset in Map Algebra, input the raster dataset as conditional raster to the Con tool.
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.
What happens to nodata in ArcGIS if the expression is nonzero?
If both the true expression and optional false raster are integer, the output raster will be integer. If the evaluation of the expression is nonzero, it is treated as True. If no input false raster or constant is specified, NoData will be assigned to those cells that do not result in True from the expression.
What happens to the output raster in ArcGIS?
If either the true raster or optional false raster is floating point, the output raster will be floating point. If both the true expression and optional false raster are integer, the output raster will be integer. If the evaluation of the expression is nonzero, it is treated as True.
What does nodata mean in conditional input raster?
Cells assigned NoData will receive NoData as output. NoData does not equate to false. A number of Spatial Analyst tools can be used to create a conditional input raster. In particular, the logical tools in the Math toolbox can be used, with the Test tool being particularly useful.
