What does the mask setting mean in ArcGIS?
The Mask environment applies to ArcGIS Spatial Analyst extension and ArcGIS Geostatistical Analyst extension tools that output a raster. It also applies to tools in the ArcGIS 3D Analyst extension Raster Interpolation, Raster Math, Raster Reclass, and Raster Surface toolsets that output a raster. The mask can be a raster or a feature dataset.
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.
How does a mask work in a raster?
If the mask dataset is a raster, all cells with a value will compose the mask. Cells that are NoData in a raster mask will be NoData in the output. If a feature dataset is used as input for the mask, it will be converted internally to a raster on execution.
What are the operators in raster calculator in Python?
Numbers and scalars can be directly entered into an expression. 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.
When to use in raster or feature Mask in Python?
When the Input raster ( in_raster in Python) and a raster Input raster mask or feature mask data data ( in_mask_data in Python) are of the same cell size, and the cells are aligned, they will be used directly in the tool. They will not be resampled internally during tool execution.
How to extract cells from a mask in ArcGIS?
The output raster containing the cell values extracted from the input raster. This example extracts cells from a raster within a mask defined by an input polygon shapefile feature class. This example extracts cells from a raster within a mask defined by an input polygon shapefile feature class.
How to get a property from a raster in Python?
The property returned is displayed in the Results window. The Python result of this tool is a geoprocessing Result object. In order to obtain the string value, use the Result object’s getOutput method. The raster containing the properties to retrieve. The property to be obtained from the input raster.
How can I create a raster analysis mask?
Tools such as Reclassify and Con can help create a raster analysis mask. If the analysis mask is a feature class or feature layer, it will be converted internally to a raster upon execution. For this reason, ensure that the Cell Size and Snap Raster environments are set appropriately for your analysis.
How is variable depth masking used in ArcMap?
About printing and exporting maps with masks In ArcMap, variable-depth masking is a drawing technique used to hide parts of layers that are drawn underneath symbols and annotation. This topic describes how to use polygons to mask underneath map layers to overlay dense symbols and to make maps more readable and useful.
How does feature outline mask work in ArcMap?
Intersecting Layers Masks The Feature Outline Masks tool works on a layer in your current map document in ArcMap or on any layer file (.lyr). A polygon feature class is generated as output in a geodatabase. These mask polygons are subsequently used to mask out portions of layers that will lie underneath certain symbols or annotation features.
