ET GeoWizards Toolbox
Calculate Length
Calculates the length of polylines or the perimeter of polygons. Please see the explanations below
Command line syntax
ET_GPCalculateLength <input_dataset> {calc_spatial_reference} { | Meters | Kilometers | Feet | Miles | Yards | Inches | Centimeters | Millimeters} {Length_field}
Parameters
| Expression | Explanation |
|---|---|
| <input_dataset> | A Polyline or 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 |
| { | Meters | Kilometers | Feet | Miles | Yards | Inches | Centimeters | Millimeters} | Output
Units. A String that defines the units in which the length 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!!! |
| {Length_field} | Length Field. A String indicating an existing field in which the results for the length will be stored. If not specified a new field "ET_Length" will be created |
