Solomon Tisdale Memorial Golf Tournament

G-Squared hosts the 27th Annual Solomon Tisdale Memorial Golf Tournament at the AATA Conference. This year was a great turn out with 40 players and, aside from a slight weather delay, went off without a hitch. We always look forward to getting out on the course with members of the AATA and encourage anyone interested to sign up for next year.

It takes a great effort to organize these events. We would like to give a shout out to those who helped make it happen this year.

TNGIC Board Member

Zach Galyen, project manager at G-Squared, has recently been elected as a Tennessee Geographic Information Council board member. This organization’s purpose is to strengthen communication between local government agencies. Through conferences, presentation, and academic involvement, TNGIC helps to create dialog amongst the GIS community. This of course facilitates the spreading of new ideas and techniques as well as technological advancements. Most important of all, the level of openness in this community helps prevent duplication of data. This group does great job bringing this geospatial community together and G-Squared is happy to be involved.

More information about TNGIC can be found on their website

G-Squared will be attending the MAPPS conference in July. The MAPPS group is an association of photogrammetry, mapping and geospatial firms. This has done a lot of great work for the industry as a whole and we enjoy being a part of it.

GIS of Alabama Conference

G-Squared is going to the GIS of Alabama conference next week. The GISA is a collaboration of multiple Alabama agencies whose purpose is to find the best ways to utilizes spatial data. Spatial data has become extremely important over the years and its usefulness keeps expanding into many different facets of life. It’s crucial to have programs that bring the users of this kind of data together so innovative ideas can flourish. It’s a never ending learning experience when dealing with geographic data!


G-Squared Presentation at Local South Lincoln Elementary School Career Day


With a steadily growing demand for GIS and Geospatial data, I feel it’s important to inform our nation’s youth on how applicable these things are and will be.

I was proud to explain to the students what it is we do at G-Squared. The students were intrigued and engaged which was expected considering the interesting world of geospatial data. The student’s desire to know more made the day all the more enjoyable. Most students however seemed to have different future aspirations beyond aerial survey and mapping. It was nice to let all the students know that geospatial data has a place no matter what you do. The possibilities are endless so long as a younger generation is thinking geospatially.
