When creating a buffer, the buffer feature layer may overlap a polygon feature layer in ArcGIS Pro. Sometimes it is necessary to calculate the area of the polygon and exclude the overlapping part of the buffer layer to perform another new spatial analysis specifically for that area on...
Calculate the width of a specific area of a polygon Create a new line feature on the top of the polygon. Refer toArcGIS Pro: Create a polyline featurefor instructions. Draw a line feature on top of the polygon to the desired angle. In ArcGIS Pro, in theContentspane, right-cli...
Calculates area values for each feature in a polygon feature class. Ältere Versionen: Because there are easier and more efficient ways to get the area of features, the Calculate Areas tool has been deprecated. Use the Calculate Field tool or the Geometry Calculator instead of the Calculate Ar...
To calculate area and length in Python, use the getArea and getLength methods with a method and unit type. To calculate the geodesic area of polygons in square kilometers, use the following expression: !shape.getArea('GEODESIC', 'SQUAREKILOMETERS')! To calculate the planar length of polyline...
AREA_GEODESIC—The shape-preserving geodesic area of each polygon feature. CENTROID_X—The centroid x-coordinate of each feature. CENTROID_Y—The centroid y-coordinate of each feature. CENTROID_Z—The centroid z-coordinate of each feature. ...

This tool is now available in Map Viewer, the modern map-making tool in ArcGIS Online. To learn more, see Calculate Density (Map Viewer). The Calculate Density tool uses input point or line features to calculate a density map within an area of interest. Workflow diagram Examples The City...
If the default value ofNoneis used, each location will be assumed to represent a single count. Input barrier featuresspecifies the dataset that defines the barriers. The barriers can be a feature layer of polyline or polygon features.You can choose a layer using theLayerbutton, or you can cr...
Population fieldspecifies the number of incidents at each location. The field type is numerical. If the default value ofNoneis used, each location will be assumed to represent a single count. Clip output todefines the area where densities will be calculated.You can choose a layer using theLaye...
Mask—Specifies a mask layer, where only the cells that fall within the mask area will be used for analysis. Parallel processing factor—Controls the raster processing CPU or GPU instances. Similar tools and raster functions Use Calculate Density tool to take known quantities of some phenomenon an...
