Charles E. Brady III, GISP

City of Ardmore, OK


Since 2000 I have been the GIS Coordinator for the City of Ardmore, OK. During that time I have been involved in managing and overseeing every aspect of municipal mapping, focusing heavily on GIS Implementation and its integration into 911, Surveying, Photogrammetry, Emergency, and Asset Management. I currently serve as the appointed Municipal Representative for the Oklahoma State GI Council as well as several other leadership roles throughout my local, state, and regional GIS community.

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.

Laurelee Gann

Conference Coordinator Elect 

Madeline Dillner

Oklahoma Corporation Commission

Oklahoma Representative

"Everything is related to everything else. But near things are more related than distant things.” 

When one of my professors told us Tobler’s first law of geography in college, I knew I’d found the right profession. I live to find patterns and show them to others. When I was 12 I read the book Life by the Numbers that talked about fractals in nature, and it was intoxicating to me. It taught me that patterns can be observed, noted, and used to make predictions in the natural world. That is, patterns bring order to what seems like chaos. So, this analysis of patterns became a constant, underlying hum in my thoughts throughout my life. Naturally, this led me to geography in college—the study of patterns and arrangements of places and people. Before graduation, I had begun working for the Oklahoma Corporation Commission as a GIS intern, and today I am the Project Coordinator for the OCC Brownfield Program, and I manage the Oklahoma Historical Aerial Digitization Project. GIS and cartography, especially the Story Map capabilities of ArcGIS Online, are the perfect instruments for displaying patterns in beautiful ways, and I love them for that. I am happy to be part of a group that appreciates them as I do. In my free time, I like to continue my pattern-seeking by exploring the US and the world, and painting and writing to express what I find.
