Betsi Chatham, GISP

City of Fort Worth

Conference Coordinator Elect

Since 1999, I have been an active member of SCAUG, and have served on the SCAUG Board in the conference coordinating capacity over the years.  I have a true and passionate understanding for the technology and people that have built this organization, and consider myself honored to be a part of the SCAUG family.

Growing up in a military family, I always found myself being introduced to new places, and as a result I constantly had questions about how the environment around me actually worked.  My quest for geographic knowledge landed me a Bachelor of Arts in Geomorphology from Arizona State University in 1993 and a Masters in Applied Geography from Southwest Texas State University in 1998.  My career has allowed me to map natural resources along the Texas Coastal Bend for Texas Parks & Wildlife, and provide National Pollutant Discharge Elimination System geospatial support for the City of Dallas.  Currently, I manage the environmental GIS efforts and play an integral role in emergency preparedness and response for the City of Fort Worth.
