Confined Space

At EROCK, we understand the difficulties that come with data collection and analysis in confined spaces. When our client wanted to gather information about a space that was too small for a lidar drone to access, we utilized a combination of confined space photogrammetry and lidar technology to provide a comprehensive solution.

Our team captured high-resolution images of the area using photogrammetry and processed the data to create a detailed representation of the space. This information was then combined with lidar data to provide our client with an accurate and in-depth understanding of the restricted area. This innovative approach to data collection and analysis demonstrates EROCK’s commitment to finding creative solutions to challenging data collection problems.
