Calculate Area
This function is not available via the GUI of ET GeoWizards.
Calculates the area of polygons. Please see the explanations below
Command line syntax
ET_GPCalculateArea <input_dataset> {calc_spatial_reference} { | Square Meters | Square Kilometers | Acres | Square Miles | Hectares | Square Yards | Square Feet} {Area_field}
Parameters
| Expression | Explanation |
|---|---|
| <input_dataset> | A Polygon feature class or feature layer. |
| {calc_spatial_reference} | The
spatial reference in which the calculations will be performed. If not
specified the spatial reference of the input dataset will be used. NOTE: The spatial reference of the input dataset and the Calculations spatial reference must have the same Geographic Coordinate System |
| { | Square Meters | Square Kilometers | Acres | Square Miles | Hectares | Square Yards | Square Feet} | Output
Units. A String that defines the units in which the area will be
calculated. NOTE: If the the Calculations spatial reference is a Geographic Coordinate System, this parameter will be ignored and the results will be calculated in decimal degrees!!! |
| {Area_field} | Area Field. A String indicating an existing field in which the results for the area will be stored. If not specified a new field "ET_Area" will be created |
Scripting syntax
ET_GPCalculateArea (input_dataset, calc_spatial_reference, output_units, Area_field)
