A map of your site
you can measure from.
Overhead imagery stitched into one high-resolution map of the whole site, flown on a date you choose. Pull distances, areas and counts straight off it — at standard accuracy for planning and estimating, or RTK-corrected when the numbers need to be tighter.
From $499 standard · From $999 RTK precision
How accurate do your numbers need to be?
Both tiers produce a measurable map of your site. The difference is how the imagery is positioned — and therefore how much weight the measurements will carry downstream.
The whole site in one image, with measurements good enough to plan and estimate from.
- Stitched overhead map of the full site, high resolution
- Measure distances, areas and counts directly off the map
- Accuracy is relative to the imagery — working figures, not tied to survey control
- Dated capture, so you know exactly when it was flown
- Delivered as high-resolution image files by secure link
Right for site planning, staging and laydown, coordination, owner updates, and point-in-time records.
Flown with RTK positioning, so the map is geo-referenced to centimeter-level control rather than estimated from the imagery alone.
- Everything in the standard tier
- RTK-corrected capture — centimeter-level positioning on every frame
- Geo-referenced output, so the map lines up with your other site data
- Measurements suitable for engineering coordination, quantity estimating and as-built documentation
- Repeat flights align to each other, so change over time is measurable
Right when someone downstream is going to rely on the numbers — a design team, a subcontractor, a project owner.
Neither tier is a survey. RTK buys accuracy, not legal standing — see below.
Measurement, yes. Surveying, no.
The distinction isn’t whether you can measure — you can, at both tiers. It’s whether the result carries professional certification. It doesn’t, and no amount of accuracy changes that.
- Measure distances, areas and counts across the site
- Estimate quantities and material for planning and bidding
- Coordinate layout, staging, access and phasing
- Compare two dated captures to see what changed
- Document as-built conditions for your own project record
- Share and mark up a current picture of the whole site
- Boundary determination, property lines or corners
- Easements, rights-of-way or encroachment determinations
- Plats, legal descriptions or anything recorded
- Certified, sealed, stamped or signed deliverables
- Any purpose requiring a licensed professional surveyor
- Design or construction work that requires certified survey data
We are not a surveying firm
Docu-Fly does not provide land surveying services. We are an aerial documentation and mapping company. We are not a licensed surveying firm, our personnel are not licensed professional surveyors, and nothing we produce is certified, sealed, stamped or signed as survey work.
Our maps and the measurements taken from them are provided for planning, estimating, coordination and documentation purposes. They are not a substitute for a boundary survey, an ALTA survey, a topographic survey, or any other survey product, and they may not be used to establish property boundaries, corners, easements or legal descriptions.
Where your project requires certified survey data, a recorded boundary, or a stamped drawing, that work must be performed by a licensed professional surveyor. We’re glad to fly the site and hand our imagery to whoever you hire — it often makes their job faster — but we won’t sell you our product as a replacement for theirs.
Four jobs these maps do well
Site planning & staging
Where laydown goes, where trailers sit, how traffic moves, which access points actually work — and how much room each of those takes. Measuring off one shared overhead image settles those conversations faster than describing them.
Quantities & takeoffs
Area of a pad, length of a run, footprint of a structure, count of what’s on site. Standard accuracy is fine for a working estimate; RTK is the call when the figure goes into a bid someone will hold you to.
Owner and lender updates
A whole-site image at a known date tells people who aren’t on site more than a schedule does. Pairs naturally with progress documentation flown on the same visit.
As-built & point-in-time documentation
What the site looked like on a given day — before mobilization, at a phase change, at closeout. With RTK, repeat flights align to each other, so change between two dates is measurable rather than just visible.
Mostly people with more site than they can see
Municipal and public works projects are welcome — we’ve done corridor documentation for a Tri-State town. Tell us the project and we’ll tell you honestly which tier fits, or whether you need a surveyor instead of us.
Priced by site and by tier
Coverage area drives the flight, so acreage is the main variable. Both starting rates cover sites up to about five acres. No subscription, no minimum.
Measurable site map at standard accuracy
RTK-corrected, geo-referenced, tighter tolerances
Larger, multi-site or recurring? Sites beyond about five acres, multi-site programs and scheduled repeat captures are quoted individually — send the addresses and how often you want them flown.
Already running progress documentation? A map flown on the same visit costs less than a separate trip.
Send the site, pick a tier
Tell Us the Site
Address, rough acreage, what the numbers are for, and when you need it. That last part usually decides the tier — we’ll say which one you actually need.
We Fly the Grid
An FAA-licensed pilot flies a planned overlapping pattern, RTK-corrected on the precision tier. Scheduled around your operations and coordinated so we’re not working over active crews.
You Get the Map
Frames are stitched, checked and delivered by secure link. Processing takes longer than a straight photo job, and the RTK tier longer still — worth knowing when you plan around it.
The questions that decide this
Is this a survey? Can I use it for property lines?
No, to both, at either tier. Docu-Fly is not a licensed surveying firm and does not provide land surveying services. Nothing we produce is certified, sealed or stamped, and none of it may be used to establish boundaries, corners, easements or legal descriptions. RTK improves accuracy; it does not confer professional certification, and no amount of precision substitutes for a licensed surveyor’s seal. If your project needs certified data or a recorded boundary, hire a surveyor — we’ll happily hand them our imagery.
So can I actually take measurements off it, or not?
Yes. Both tiers produce a measurable map — distances, areas, counts, footprints. On the standard tier, treat those as working figures: accurate enough to plan, stage, estimate and coordinate from. On the RTK tier the positioning is much tighter, which is what you want when the number leaves your hands and someone else relies on it. What neither tier gives you is a certified number.
Which tier do I need?
Ask what happens to the number. If it’s informing your own planning, staging or a ballpark estimate, standard at $499 is the right size. If it’s going into a bid, a design coordination package, a quantity someone gets paid against, or an as-built record you’ll compare future flights to, pay for RTK. When you tell us what the map is for, we’ll tell you which one — including when the cheaper one is fine.
What does RTK actually change?
On a standard flight, the drone’s position on each frame comes from ordinary GPS, and the software reconciles the rest from the imagery. With RTK, the aircraft receives a live correction stream and records centimeter-level positioning on every frame, so the finished map is geo-referenced rather than inferred. Practically: measurements hold up better, the map lines up with your other site data, and repeat flights align to each other.
Do you publish an accuracy tolerance?
Not as a blanket number, because real-world accuracy depends on the site, the flight plan, ground conditions and how much of the site is obstructed. Tell us what tolerance your use actually requires and we’ll tell you honestly whether we can meet it on your site — and if we can’t, we’ll say so rather than deliver something that misses.
How big a site can you cover?
Both starting rates cover sites up to roughly five acres. Larger is quoted — coverage area drives flight time and processing, so a thirty-acre site is a different job rather than the same job with a bigger number.
What if part of the site is obstructed?
Heavy tree canopy, permanent structures or anything else we can’t see over gets flagged rather than filled in. An overhead map can’t show what’s underneath something, and we’d rather tell you what’s obscured than let you assume it isn’t.
Can you fly an active jobsite?
Yes. FAA Part 107 licensed, fully insured, scheduled around your operations and coordinated with your site so we’re not overflying active crews. We handle airspace authorization, which a fair number of Tri-State addresses need because of the airport.
Tell us what the numbers are for.
That’s the question that picks the tier, and we’d rather ask it than sell you the expensive one by default. Send the address and what you’re trying to do with the map.
