Unmanned Aerial Vehicle Services

The ability to visualize information, particularly from different perspectives or inaccessible areas, improves communication and understanding far more effectively than a written description.


The expression “a picture is worth a thousand words” is arguably truer today in our fast-paced world than ever before. As the public becomes more technologically sophisticated with higher expectations of the communities in which they live, it is more important than ever to deliver high-quality information in a manner that’s timely, environmentally friendly, low impact, and safe.

EST’s unmanned aerial vehicle (UAV) or drone division utilizes superior cutting-edge technology to take civil engineering, land surveying, and inspection services to an elevated level. EST drones can capture high-definition video in less than two hours, which supplies visual outputs and enables timely and accurate digital 3D models for virtually limitless applications. EST’s staff has extensive experience with these advancing technologies and can quickly identify the best tool to use based on each client’s needs.
