Houston GIS Day
GIS Day is celebrated around the world and is one the AllTerra Central team is always proud to be a part of. Teaching and mentoring local high school students about how GIS is used in their communities is always a great way to get them thinking about a future in our ever growing industries. Whether we are teaching them how to use Trimble Surveying or Mapping geospatial equipment to capture and locate assets in the field or teaching them the ways drones are used to mapped our lands we enjoy spreading the word and hoping that one day we will see them out working in the industries we serve making maps and teaching others. AllTerra is proud to have been a part of the Houston Area GIS Day from day one back in 2001 and we will continue to serve our great community and work with some of the best high schools in the area.
Texas A&M University
AllTerra Central teamed up with the Trimble Education Team and was able to provide Trimble equipment to Texas A&M University in College Station with their state of art Trimble Technology Lab and all the equipment to support the field side. Supporting higher education is so important and allows us to make sure these students are not only ready when they earn their degrees from TAMU but when they hit their new career they can walk the walk when it comes to using the latest in Trimble Geospatial equipment. We were we so fortunate that we were able to donate Trimble equipment into the Construction Sciences, Geospatial and the Forensics Departments. We are here for the long haul and our teams enjoy ongoing trips to campus to educate on the equipment and keep that geospatial momentum going!
Tyler Junior College
Each year AllTerra Central donates funds to TSPS Chapter 4 and this donation allows AllTerra to donate the Surveying Textbook for incoming Freshman students to Tyler Junior College’s Geomatics Program. The thank you cards alone make this one worth it each year. Reading each card and learning about each student’s plan and how grateful they are for one less expense is reason enough. The best part is when you attend the ceremony when they receive the books and see the wall of surveyors in the room supporting each and every student is by far the most inspiring site to see. Being a small part of their journey with something as simple as a textbook is something AllTerra will continue each year. Let’s all work to support our students who are working hard to be the next generation of Texas Professional Land Surveyors.
Pipeliners Association of Houston
AllTerra Central’s Key Accounts team is always up to the fishing challenge and nothing keeps them from getting out there with our amazing colleagues in the industry and fishing the day away. Even though they are enjoying some great fishing they are helping to raise funds for the Pipeliners of Houston (PAH) scholarship fund. Raising these funds allows PAH to provide scholarships to those earning their education for oil and gas related fields. With PAH putting on such fun and engaging events they have made sure these scholarships will continue to be funded. So if you see one of our guys with a fishing pole, we promise he is out doing his part for education and maybe some bragging rights.
Make-A-Wish and Helping Hand Home
Every Christmas, AllTerra Central picks one organization to support. In 2025, we couldn't choose just one, so we went over budget and gave to two: Make-A-Wish and Helping Hand Home in Austin.
Make-A-Wish grants wishes to children with critical illnesses. They might get to be a police officer for a day or take their family to Disney World. For these kids, it's a once-in-a-lifetime experience, and every story we hear moves us.
Helping Hand Home gives hope and healing to children who have been through trauma. It provides therapy, foster care, adoption services and support for each child's well-being and education. Every child deserves a safe, loving home, and we're proud to play a small part in that work.
