Jenness Enterprises is owned and operated by Jeff Jenness and Lois Engelman in Flagstaff, Arizona, USA.  We specialize in developing customized applications for the Windows™ operating system and Esri's ArcGIS Geographic Information System.  Please visit our Unit Converter site to find a useful tool for anyone who has ever had to convert measurement units, and our ArcView Extensions site for a variety of free applications for the ArcView GIS system.  Details on our GIS Consultation services are available on our Consultation site.

     We also have a few items available relating to Mexican spotted owls.  Jeff Jenness has conducted research on these birds since 1987 through the U.S. Forest Service and Northern Arizona University.  See our Literature page for links to on-line documents authored or co-authored by Jeff Jenness.
