Aerial mapping & photogrammetry · Tier 1, measurable
Verified Capture
Corrected, controlled and independently graded. When somebody downstream is going to measure from the model, take a quantity off it, or design against it, this is the tier that survives the question of where the numbers came from.
Method
Accuracy is measured, not asserted.
Measured independently of the software that produced the model, and reported with the data. If that distinction means something to you, you already know why it matters.
- CONTROLGNSS-positioned ground control established on site, independent of any third-party correction feed.
- VERIFICATIONGraded against evidence the reconstruction never saw.
- RECORDCorrection state, reference frame and epoch delivered with the data, so the result can be checked by whoever receives it.
The flight is evidence too
How a site is flown decides what the reconstruction can resolve, long before any processing happens. The capture is planned against the deliverable and the plan is retained with it, so a result can be traced back to the mission that produced it.
A capture that cannot be described step by step is a capture that cannot be repeated, and one that cannot be repeated cannot be defended.
Deliverables
What arrives.
Measured products
- Orthomosaics at specified ground sample distance
- Digital surface and digital terrain models
- Classified and unclassified point clouds
- Textured 3D meshes and digital twins
- Contours, cross sections and volumetric computations
- Asset inventories and extracted features
The record that comes with them
- Independent validation record, delivered with the data
- Correction state of the capture (RTK / PPK / uncorrected)
- Coordinate reference frame, vertical datum and epoch
- Source tagging on every reported attribute: measured, observed, reported, or not assessed
- A written statement of what was not captured and why
Integration
Delivered into the systems you already run rather than a platform you have to adopt. ArcGIS Pro and ArcGIS Online, QGIS, CAD, and standard interchange formats.
Most clients already own capable software and are using a fraction of it. Replacing that is rarely the right recommendation, so we do not lead with it.
Strip the texture and the geometry is what remains
Photographs make a site look convincing. Geometry is what you take a dimension from. Every product in this tier is built so the second one holds up on its own, without the first one carrying it.
Proof
Two Arizona sites this tier was built on.
- INFRASTRUCTUREThe Gillespie Dam Bridge, documented in 3D — a 1927 steel through truss over the Gila, captured with multi-source reality capture.
- CONSTRUCTIONVerrado Marketplace, documented during active construction — a commercial retail development in Buckeye.
Verified Capture is a geospatial mapping product. It is not a substitute for work requiring a licensed professional.
Applications
Where this tier is the right answer.
- Infrastructure and bridge documentation, including historic and heritage structures
- Construction progress verification and earthwork volumes
- Corridor and utility mapping, right-of-way base data, as-built support
- Facility and public safety pre-incident intelligence
- Multi-temporal change detection where two dates have to be comparable
- Any deliverable a third party will measure from, design against, or rely on in a submittal
Limits, stated up front
What Verified Capture is not.
It is a geospatial mapping product, not a regulated professional service. Axis Fields delivers measurable, independently validated spatial data. That is a narrower claim than the one a licensed professional makes, and we hold the line on it.
Where a project requires a stamped, certified product, that work belongs to a licensed professional. If your project already has one engaged, we coordinate directly and our data is theirs to check. Independent verification is welcome, not something we route around. Tell us early and the whole job costs less.
Photogrammetry and lidar do not see through walls. No interior access means interiors come back hollow. We say so in writing before collection, not after, because a responder who does not know a space is unmapped will assume it is mapped.
A datasheet figure is not a result. We will not quote a sensor's relative accuracy specification as though it were verified absolute accuracy achieved on your site. If you have been handed a number like that, ask what it was validated against.
Price
What it costs to start.
Equipment
The tier is enforced by the hardware, not the invoice.
Verified work flies on specific aircraft with specific ground equipment. A Visual Capture aircraft cannot be upgraded into this tier by relabelling the job.
- AIRCRAFTAn RTK-capable mapping airframe with a mechanical shutter, assigned to this tier and recorded per mission. A visual-tier aircraft is never reassigned into it.
- GNSSOur own base and rover, logging raw observations for independent post-processing rather than relying on a third-party correction feed.
- TERRESTRIALHandheld lidar for geometry the aerial capture cannot reach, used to fill occluded surfaces.
- PROCESSINGIn-house photogrammetric processing, 3D reconstruction and independent quality-control checks, delivered into the GIS and CAD formats your systems already read.
What decision does the data have to support?
Answer that and the control plan, the aircraft, the ground sample distance and the price all follow from it.
