Service 02
Create measurable 2D and 3D site records using coordinated image capture and photogrammetric processing.
Applications
Mapping is selected when a site needs overview, measurement, or a repeatable spatial record over time.
Shared spatial records of grading, utilities, pads, and access as work advances.
A baseline of current layout before design or construction changes the site.
Scaled coverage of property layout, access, and surrounding context.
Volume context derived from the processed surface when scoped.
Yards, plants, and operational areas where a measurable overview is useful.
Coverage that is difficult to assemble from ground photography alone.
Surface and elevation context for planning and later comparison.
Repeatable capture so later visits can be compared to an earlier state.
Deliverables
Scaled aerial maps that show site layout, access, and change over time.
Spatial datasets that support measurement, context, and further analysis.
Reconstructed site geometry for remote review and communication.
Cut, fill, or stockpile quantities when the capture is scoped for volume.
Terrain context derived from the processed model when requested.
Still coverage for conditions, staging, and visual reference.
Agreed files for GIS, CAD, or review workflows.
Deliverables are selected according to project scope, site conditions, and documentation objectives. Technical exports such as GeoTIFF, LAS, or OBJ are provided when the processing method and engagement specify them.
Method
Overlapping stills are captured across the site, aligned through common features, and reconstructed into measurable spatial products.
Measurement quality depends on capture geometry, processing, and any control used for the engagement. It is not a universal accuracy claim.
Positioning
A photograph documents one viewpoint. A mapped dataset preserves spatial relationships across an area.
Individual stills remain useful for specific observations. They do not, by themselves, reconstruct distances, layout, or how one location relates to another. Photogrammetric products exist to keep those relationships available after the site has changed.
Example mapped record
Products
An orthomosaic is a scaled aerial map. It removes the single-photo perspective so layout, access, and change can be reviewed across a site. A point cloud is the dense spatial dataset behind that view, used when measurement or further analysis needs geometry rather than an image. A 3D model is the navigable surface built from the same capture, useful when a team needs to look at form, progress, or context remotely.
Elevation and surface products describe terrain shape when the capture supports them. Volumetric outputs estimate stockpile or earthwork quantities from that surface. Recurring documentation repeats a compatible capture so a later visit can be compared with an earlier one. Construction progression is one use of that repeatability: grading, pads, utilities, and structure recorded while they are still visible.
Exports
Agreed exports such as GeoTIFF, LAS, OBJ, or a web map are provided when the processing method and the engagement specify them. The file format does not add accuracy. Control, when used, ties the model to known positions. Without it, the record can still preserve relative layout, and measurements should be treated as relative to that capture.
Photogrammetric elevation context is not a licensed topographic survey. Boundary, easement, and other legal survey products remain with a licensed surveyor. SterFlies can document the visible surface. It does not certify property lines or pay quantities.
Limits
Vegetation, water, glass, moving equipment, and low texture can leave gaps or noise. Flight limits and active construction can block coverage. A single visit documents that visit. Work completed or covered between visits is absent unless it was captured while visible.
Those limits belong in the project record. They are the difference between a useful site document and a claim the data cannot support.
Project
An example of recurring aerial mapping. No universal accuracy claim is attached to this project.
