Regardless of whether you have a whole GIS department with staff and a large budget or you are the one person shop with only a strong desire to work and a big job ahead of you, my goal has and always will be, to ensure that SCAUG is there to help you. At the end of the day my desire is for you to feel educated, successful, welcome, and appreciated by SCAUG. Personally I welcome your ideas to continue building on what SCAUG offers to the GIS community in order to insure SCAUG continues to be your professional home base for the future.

Betsi Chatham

City of Fort Worth

Conference Coordinator 

I operate in the manner of advice from Albert Einstein, “strive not to be a success, but rather to be of value”.  I have been an active member of SCAUG since 1999, 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.  Since 2000, I have managed the environmental GIS efforts and played an integral role in Emergency Management at the City of Fort Worth.  On my down time I enjoy working in my yard, BBQing, and live music.  I am an avid Texas Rangers fan, and proud mother of my beautiful daughter Jade Elizabeth.
