Extent

This view allows you to input two types of extent:

1. Estimated Geometric Extent – Automatically calculated based on the dimensions (area, length, etc.) of the activity’s geometry. Many models and activity types require a unit input tied to geographic extent, so this value is useful to keep with your activity record.

2. User-Defined Extent – If your geometry doesn’t include a measurable extent (e.g., a point location), or if the estimate is inaccurate, you can manually enter an extent and select the appropriate unit. This will override the FieldDoc estimated extent, however the system-generated field will remain visible (you cannot delete it).

FieldDoc Field Name	Import Field Name	Description
User Defined Extent	practice:extent	Enter in a numerical value for the activity record extent.
Unit	practice:extent_unit	Enter in the unit type, such as acres or linear feet.

The Extent fields are not automatically used to calculate most models. To run a model, you must enter in the unit input (which may be the extent available from this page) into the corresponding model input field and then press run.
