Specification sheet

Capabilities

Aircraft, sensors, output formats, turnaround windows and stated accuracy — with the conditions each figure depends on. If a number here doesn't cover your case, send the plan set and you'll get one that does.

§1 Aircraft §2 Sensors §3 Ground control §4 Output formats §5 Accuracy §6 Turnaround §7 Limits

§1

Aircraft

Aircraft platform, class, positioning method and what it flies
Platform	Class	Positioning	Flown for
DJI Matrice 400	sUAS < 55 lb	RTK / PPK	Ortho · topo · takeoff · machine control

Flown by an FAA Part 107 certificated pilot, with a second pilot available so a scheduling conflict doesn’t move your date.

§2

Sensors

RGB mapping camera

Mounted on	DJI Matrice 400
Used for	Ortho · topo · takeoff
Stated accuracy	±0.1 ft, conditions in §5

§3

Ground control & coordinate systems

Ground control practice
Ground control	Set on site by us
Tie to site control	Yes, when you provide it
Boundary control	Set by a licensed surveyor on the job

Coordinate systems and datums
Horizontal datum	NAD83 · WGS84
Vertical datum	Matched to your plan set
Custom / plan coordinates	Supported, no charge

§4

Output formats

Deliverables, file formats, target software and typical file size
Deliverable	Formats	Opens in
Machine control model	TP3 · GP3	Trimble · Topcon · Leica · John Deere
Surface / TIN	On request	Civil 3D · Trimble · Agtek
Contours	On request	AutoCAD · GIS
Quantity report	PDF	Anything

Tell us the software you’re loading into and you get the format that works in it. No conversion charge.

§5

Accuracy, with conditions

Accuracy by method, with the conditions each figure holds under and how it is verified
Method	Horizontal	Vertical	Holds when	Verified by
RTK + ground control	±0.1 ft	±0.1 ft	Bare or lightly grassed ground, with control set on site	Held-back checkpoints

The figure above is the accuracy held on bare or lightly grassed ground with control set on site. It is not a manufacturer’s spec-sheet number, and it degrades with heavy vegetation — §7 says where it stops holding.

§6

Turnaround windows

Turnaround by deliverable, and when the clock starts
Deliverable	Window	Clock starts
Quote	24 hours	Plan set received
On site	48 hours	Go-ahead, weather permitting
Earthwork takeoff	72 hours	Flight complete
Topographic map	72 hours	Flight complete
Machine control model	72 hours	Plan set received

§7

Limits — what we won't claim

Heavy canopy

Photogrammetry cannot see ground it cannot photograph. Under heavy brush or closed canopy we say so before quoting, and tell you the site needs conventional ground methods rather than selling you a surface that will not hold.

Standing water

Water surfaces do not return usable elevation. Ponded areas are flagged on the surface and excluded from volumes unless you specify a water-line elevation.

Boundary and legal descriptions

This is aerial mapping, not a licensed land survey. Property corners, easements and plats need a Texas RPLS — we will hand you off to one.

Need a figure that isn't on this sheet?

Send the plan set — the quote states the accuracy and turnaround for your site specifically.
