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

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!
