Catterall & Wright offers comprehensive surveying and UAV (Unmanned Aerial Vehicle) mapping services that provide the accurate spatial data essential to engineering design, planning, and construction. Our team combines traditional survey techniques with advanced drone technology to deliver efficient, high-quality mapping for a wide range of project needs—from topographic surveys to construction layout and volume calculations.
Our Services include:
Our services combine traditional surveying methods with advanced technology to deliver accurate and efficient site data. For preliminary topographical surveys, we assess each site to determine the most effective approach—whether by foot using GPS or total station equipment, by ATV-mounted GPS for rugged areas, or by UAV for larger or less accessible terrain. Our UAV capabilities allow us to quickly and accurately capture aerial data for terrain modeling and large-scale surface analysis. Using software like 3D Reshaper and PIX4D, we generate detailed digital terrain models (DTMs), contours, and georeferenced orthophotos to support design and planning.
During construction, our experienced field staff provide layout services and onsite quality control to ensure infrastructure is built according to design specifications. We maintain strong relationships with contractors and work collaboratively to explore practical solutions when field adjustments are needed. In addition to layout, we track earthwork quantities throughout construction, comparing actual volumes to preliminary estimates for accurate progress reporting and cost tracking. These integrated services ensure that every phase of development—from initial mapping to final verification—is supported by reliable, high-resolution spatial data.
