SimActive’s Correlator3D Speeds Up Processing of Large Drone Datasets for SurvTech

July 8, 2025 by Miriam McNabb Leave a Comment

Advanced photogrammetry software supports rapid delivery of high-quality geospatial products

SimActive Inc., a global developer of photogrammetry software, has announced that SurvTech Solutions is using its Correlator3D product to process large-scale image datasets from drones and large-format cameras. The software enables SurvTech to deliver digital surface models and orthomosaics efficiently, supporting a range of surveying and mapping projects.

A Long-Term Partnership

SurvTech Solutions, a geospatial firm based in Tampa, Florida, specializes in land and hydrographic surveying, mapping, and GIS services. The company serves clients throughout the Southeastern United States and beyond, relying on advanced technologies and a team of skilled professionals to provide accurate and timely data.

“We have been using Correlator3D for more than nine years and one of its biggest advantages is how quickly it can process large amounts of data,” said Mark Bickel, UAV Department Manager at SurvTech Solutions. “SimActive’s software handles large datasets much better than any other solution out there.”

This long-standing relationship highlights the importance of reliable and fast processing tools for companies managing complex mapping projects. In many cases, quick data turnaround is critical for decision-making, planning, and ongoing operations.

The Power of Correlator3D

SimActive’s Correlator3D is designed to process high-resolution aerial imagery from satellites, manned aircraft, and drones. The software supports the full photogrammetry workflow, including aerial triangulation, the generation of dense digital surface models (DSMs) and digital terrain models (DTMs), as well as point clouds, orthomosaics, and 3D models.

One major advantage of Correlator3D is its ability to handle large datasets quickly. The software uses GPU technology and multi-core CPUs to deliver unmatched processing speed, making it possible to create detailed geospatial products in significantly less time. This speed is especially useful for projects that require rapid data delivery or cover large areas.

Correlator3D is also often used alongside LiDAR data. When LiDAR is not used, the software can still generate high-quality surfaces using only photogrammetry, even in challenging areas like waterbodies where other tools might struggle.

Supporting Advanced Geospatial Work

SimActive has been providing Correlator3D to leading mapping firms and government organizations worldwide. By combining advanced algorithms with powerful hardware acceleration, the software enables professionals to produce precise and reliable geospatial data.

With its patented technology and strong customer support, SimActive continues to be a trusted partner for companies like SurvTech that require both quality and efficiency.
