Here are the steps for calculating the area of a polygon using ArcGIS. These steps can also be replicated for calculating the perimeter of a polygon or the length of a line file. You can use these steps to find out the acreage of a polygon by loading in a GIS dataset that uses amap ...

Learn how to calculate the length and area of geometries. You can calculate the length of a line and determine the area of a polygon using thegeometryEngine. The measurement depends on the coordinate system (orspatial reference) defined for the geometry. If the geometry's spatial reference is ...
Anarea of interest (AOI)is defined by a polygon feature that represents a specific geographic extent.InArcGIS Defense Mapping, AOI features are found in an index feature class that contains various map extents for a region or the world.The index feature class resembles a grid on a map; each...
The algorithm used by ArcGIS to calculate area is called the shoelace formula or Gauss's area formula. Esri uses a normalized form of this formula to preserve numeric precision. The algorithm calculates the area for each ring (part) in a polygon. If the ring is clockwise (oute...
An area of interest (AOI) is defined by a polygon feature that represents a specific geographic extent. In ArcGIS Production Mapping, AOI features are found in an index feature class that contains various map extents for a region or the world. The index feature class resembles a grid on a ...
TheErasetool requires an ArcGIS Desktop Advanced license and theExtract by Masktool requires a Spatial Analyst license. After a polygon feature is created on a raster, create a new feature class of a rectangular polygon that covers the entire extent of the raster. ...
ST_Area takes a geometry column and returns a double column. The output column contains the planar area of each geometry in the input column. The unit of the area calculation is the same as the units of the input geometries. For example, if you have polygons in a spatial reference that...
ArcGIS geoprocessing tool that increases the size of polygon features until they meet a specified area value.
More generally, the need might arise to convert a general raster image of an area into a polygon shapefile. You can do this with the Spatial Analyst extension for ArcGIS, but the two together are pretty expensive. There’s a somewhat painless way to do it with free software. First, here...
