This can be accomplished by calculating a bounding box using the Envelope option rather than the Rectangle by Area option in the Minimum bounding Geometry tool. This reduces the area to be mislabeled as 0 or -37286 to nothing!</P></BODY></HTML> Wed, 28 Sep 2016 17:04:48 GMT https://community.esri.com/t5/python-questions/extract-by-mask-arcpy-script-error-bad-nodata/m-p/460693#M36093 RyanAvery1 2016-09-28T17:04:48Z
