If you've heard the term "orthomosaic mapping" and wondered what it actually means for your construction project, this article breaks it down in plain English.
What Is an Orthomosaic Map?
An orthomosaic map is a high-resolution aerial image created by stitching together dozens or hundreds of overlapping drone photos. Unlike a single aerial photo, an orthomosaic is geometrically corrected — meaning it's accurate and measurable, not distorted by the angle of the camera.
Think of it as a precision aerial map of your entire project site, captured from above and stitched together into one seamless image that you can zoom into, measure, and compare over time.
How Is It Different from a Regular Aerial Photo?
A regular aerial photo gives you a visual overview of the site. An orthomosaic map gives you a tool you can actually use for planning and measurement. Because the image is geometrically corrected, distances and areas are accurate — you can measure the length of a foundation, calculate the area of a graded pad, or compare site conditions between two different dates.
Construction Use Cases
Orthomosaic mapping is used throughout the construction process for site planning and layout verification, tracking earthwork and grading progress, documenting site conditions before and after major phases, providing accurate site overviews for project managers and stakeholders, and comparing planned versus actual site conditions.
What You Receive
After a mapping flight, you receive a high-resolution orthomosaic image file that can be viewed in standard image software or imported into CAD and GIS tools. We can also provide comparison maps showing changes between two capture dates.
Remington Drones provides orthomosaic mapping services for construction projects throughout Utah's Wasatch Front, from Weber County to Utah County.
