How do you use condition in raster Calculator?
To perform conditional evaluation on a raster dataset in Map Algebra, input the raster dataset as conditional raster to the Con tool. Input a true raster to provide values to be returned when the conditional evaluation is true.
What does Con mean in ArcGIS?
Spatial Analyst
‘Con’, abbreviated for condition, is one of the most used and powerful tools in Spatial Analyst. It allows you to vary how the output is determined based on the value of the input locations, which is key for building simple as well as complex models.
What is the purpose of the raster Calculator in ArcGIS?
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 does con function do?
The Con function allows you to control the output value for each cell based on whether the cell value evaluates to true or false in a specified conditional statement. If the cell evaluates to true, it will receive one value; if it evaluates to false, it will receive another.
What is a raster calculator?
The Raster Calculator tool allows you to create and execute Map Algebra expressions in a tool. Like other geoprocessing tools, the Raster Calculator tool can be used in ModelBuilder, allowing the power of Map Algebra to be more easily integrated into your workflows.
How do I change raster value?
Click the Tools button on the ArcFuels10 toolbar then select Modify Raster Values from the drop-down list. Fill out the Modify Raster Values form following the figure below. Click the Create Raster button. A progress meter will open, then close after the raster has been created.
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.
Is the raster calculator available in ArcPy Spatial Analyst?
It is not intended for use in scripting and is not available in the ArcPy Spatial Analyst module. 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.
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 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.
