Calculating bounding box in ArcMap

Monday, July 12th, 2010


[Editor's note: I keep returning to this technique for calculating a feature's extent (minimum bounding rectangle) in ArcGIS using the Field Calculator. Thanks William and Jeff!]

Republished in part from ESRI Forums.
Sample Field Calculator code for computing XMIN appears below.

Information about shape properties appears in the “Geometry Object
” diagram (pdf). All four parameters are Xmin, Xmax, Ymin, and Ymax.

dim Output as double
dim pGeom as IGeometry

set pGeom = [shape]
Output = pGeom.Envelope.XMin
