A polygon is any flat shape that has straight lines for sides. Some common polygons are squares, parallelograms, triangles and rectangles. The area of an object is the amount of square units that are needed to fill a shape. To find the area of a shape, you simple have to measure the ...
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...
Divide 360 by the amount of the exterior angle to also find the number of sides of the polygon. For example, if the measurement of the exterior angle is 60 degrees, then dividing 360 by 60 yields 6. Six is the number of sides that the polygon has. This is a hexagon, so we can ch...

TheExtract by Polygontool has an extraction area parameter with an outside option which allows cells outside the input polygon to be selected and written to the output raster. All cells inside the polygon receive NoData values on the output raster. However, this tool does not allow the use ...
The perimeter looks right, but to make the area right either the first point must equal the last point or you need to extend the p_area by one more term, namely, (x(n)+x(1))*(y(n)-y(1)). Also you need to either ensure that your route around the polygon is clockwise or else...
