Drone 3D Mapping
A flat map tells you where things are. A 3D model lets you move around your site from any angle, measure the height of a structure, calculate the volume of a pile, and hand a client something they can explore themselves. BWM Geospatial Solutions builds accurate, measurable 3D models of sites, buildings, and facilities from aerial data.
What 3D Mapping Actually Produces
We fly the subject from multiple altitudes and angles — including oblique passes that capture building faces, not just rooftops. Processing software identifies features appearing across overlapping frames and solves the three-dimensional position of each one, reconstructing your site as a dense cloud of measured points. That geometry is surfaced and textured with the original photography.
The result isn't an artist's rendering or a stylized visualization. It's a measured reconstruction of what is physically there, at real-world dimensions, built from data captured over the actual site. You can take a measurement off it and trust the number.
What You Can Do With the Model
Measure without going back to the site. Distances between any two points, surface and roof areas, stockpile and excavation volumes, structure heights, pavement square footage. Questions that would otherwise mean another site visit get answered from your desk.
Inspect what you can't reach. Examine a roof, façade, tank, or structure in close detail without a lift, a ladder, or a rope crew.
Present work that lands. Send a link. Clients, investors, and planning boards navigate the model themselves. It communicates a project far better than a folder of photographs, and takes no software to open.
Document conditions before they change. A dated 3D record before demolition, excavation, or renovation is inexpensive to capture and extremely valuable the one time a question arises about what was there.
Plan against reality. Model an existing site before design work, or place a proposed structure into a model of the real surroundings to show how it fits.
Types of 3D Mapping We Deliver
Site models — full property or project area, terrain and structures together
Building models — a single structure from all sides, including façades and roof detail
Facility models — plants, yards, and campuses with equipment and infrastructure in place
Contextual models — existing surroundings, showing how a proposed development integrates
Asset models — towers, tanks, bridges, and equipment for inspection and documentation
Facility and Site Documentation
Large facilities are hard to see whole. Drawings go out of date, the site has been modified a dozen times since anyone updated them, and no single photograph captures it.
A 3D model gives you current, measurable documentation of the property as it exists today — for expansion planning sized against the real site rather than a decades-old drawing, asset records showing where things actually are, permit and environmental documentation with defensible area measurements, roof and pavement assessment for capital budgeting or solar feasibility, and emergency response planning with an accurate current layout.
Sites that change — active yards, expanding operations, ongoing construction — benefit from re-flying on a schedule. Because each model is georeferenced to the same coordinate system, datasets compare directly and change becomes measurable rather than impressionistic.

Detail and Accuracy
Model resolution depends on flight altitude and sensor selection. Flown close, our models resolve detail fine enough to read surface cracking in pavement and individual course lines in masonry.
With ground control established, models support measurement and estimating work. Without ground control, relative measurements within the model remain reliable while absolute positioning is looser — adequate for presentation, not for design.
Tell us which use case you're buying for and we'll fly it to the right standard. There's no reason to pay for survey-grade control on a model that exists to show a planning board what a building will look like.
Who Uses 3D Mapping
Engineers and architects — existing conditions, design context, site analysis
Developers — presenting projects to boards, investors, and communities
General contractors — pre-construction documentation, progress records, dispute avoidance
Facility and asset managers — infrastructure records, maintenance planning, capital budgeting
Municipalities and public safety — response pre-planning, public project communication
Insurance and claims — documented conditions before and after an event
Real estate and brokerage — industrial and commercial property presentation
What Drives Cost
3D models are quoted per project based on the size of the subject, how much detail you need, whether ground control is required for measurement accuracy, and which output formats your team will use. Recurring documentation programs are priced per visit.
Call with your site or building and what you'll use the model for, and we'll quote it.
