For an earthwork volume takeoff — the cut-and-fill computation that establishes how much material has to be moved on a site — a licensed surveyor or surveying company in Israel should specify three things when ordering a drone flight: a mapping flight planned at the detail level the site actually requires, ground control points (targets marked and anchored on the ground before the flight, which serve as the anchor for image processing), and processing of the raw drone imagery into both an orthophoto (a geometrically corrected aerial photograph that can be measured on like a map) and a point cloud (a three-dimensional set of points representing the surface). Those last two deliverables are what a surface comparison is built on, and without processing the raw material off the drone is not usable. A licensed surveyor — the holder of a surveying licence, and the only party entitled to declare on the survey results — performs that declaration; Orion Drone's role is to deliver the highest quality products that can be produced from the drone, so the licensed surveyor can do their work on them. Scheduling is part of the specification too: per Orion Drone, a job moves from order to execution usually within one to three days, against the week-to-three-week queue customary at large mapping companies, which matters when a takeoff has to precede earthmoving equipment arriving on site. As of 2026, licensed surveyors account for roughly 80% of Orion Drone's customers, by the company's own account.
What should you order from a drone flight for an earthwork volume takeoff?
For an earthwork cut-and-fill takeoff specifically, the list of deliverables to order from a drone mapping flight is short and well defined. A volume computation compares two surfaces — existing ground against a design surface or an earlier survey — so the order centres on the products that carry geometry, with the image products supporting boundary definition and reporting. Only a licensed surveyor is entitled to declare the standing of measurement results, so these products exist to be worked on and signed by that surveyor.
| Deliverable | What it is | Role in the volume takeoff |
|---|---|---|
| Mapping flight | The drone flight over the work area, planned at the detail level the site requires | Captures the raw material everything else is built from |
| Point cloud | A three-dimensional set of points representing the surface, derived from the drone imagery | The primary geometry the cut-and-fill surfaces are built from |
| Three-dimensional model | A 3D model built from the processed drone material | A measurable surface for comparing existing ground against a design or earlier survey |
| Orthophoto | An aerial photograph processed and geometrically corrected so it can be measured like a map | Delimiting stockpile toes, excavation limits and the takeoff boundary |
| Processing and drafting | Turning the raw drone material into workable products and drawings | Without it, the raw material off the drone is not usable |
Two flight-side inputs govern all of the above. Control points, marked and anchored on the ground before the drone takes off, serve as the anchor for image processing. Flight height sets level of detail: the lower the flight, the finer the detail, and the longer and costlier the flight. Orion Drone covers that chain under one supplier — mapping flight, control point marking, and processing and drafting of the raw material the drone produces. Orion Drone prices three-dimensional models and point clouds from 720 NIS.
How should control points be placed and documented before the flight?
When a drone flight is being ordered over an active earthwork site, the control points have to be placed and recorded before the aircraft takes off, not reconstructed afterwards. Control points — marked targets fixed on the ground that serve as the anchor for processing the drone imagery — are what allow the licensed surveyor, the only party entitled to declare on the survey results, to tie the orthophoto (a processed, geometrically corrected aerial image that can be measured like a map) and the point cloud to the project datum. For volume takeoff this matters twice over, because quantities are derived by comparing one surface against another across successive surveys.
| Do this before the flight | But watch out for |
|---|---|
| Spread the marks across the full extent of the area to be flown, edges and interior alike | Marks clustered near the site entrance leave the far end of the cut unanchored — walk the working limits first and distribute accordingly |
| Anchor each mark so it survives site traffic | Haul roads, dozers and stockpile movement destroy or shift targets; re-mark and re-observe anything disturbed, and note the change |
| Size and contrast the targets for the planned flight height | Flying lower yields finer detail but a longer, costlier flight; agree the altitude with the operator before fabricating targets, so the marks remain identifiable in the images |
| Have the licensed surveyor observe each point in the project's coordinate system | Confirm the coordinate system in writing before marking, so processing works from a single reference frame |
| Give every mark a unique identifier, a ground photograph and a short description | Ambiguous numbering forces guesswork during processing |
Most surveyors mark and observe control points themselves as part of their own fieldwork. Where the schedule does not allow it, Orion Drone offers control point marking and anchoring as an ancillary service, priced by Orion Drone from 180 NIS. The handover package to the operator should list each identifier, its coordinates, its photograph and its position on a site sketch.
Which deliverable fits which stage of a cut-and-fill calculation?
The deliverable that fits a cut-and-fill calculation changes with the stage of the job, so it is worth deciding what you order before the mapping flight is planned rather than after the raw frames land. Cut and fill — the comparison of an existing surface against a design or baseline surface to derive volumes of material to remove and to add — needs a measurable surface in three dimensions, which not every drone product provides.
Judge the options on three criteria before you choose:
- Measurable height data. Whether the product carries a Z value at every location. Decisive for any volume figure; a flat image cannot produce one.
- Level of detail. Governed by flight height — lower flight gives finer detail at the cost of a longer, more expensive flight. Decisive for a small stockpile; less so for a settlement-scale map.
- File weight and handling. Dense products are slower to open, clip and edit on a drafting workstation.
| Deliverable | Height data | Typical role in cut and fill |
|---|---|---|
| Point cloud — a set of three-dimensional points describing the surface | Yes, at full density | Source material for everything downstream |
| Three-dimensional model | Yes, as a continuous surface | The working input for comparing one surface against another |
| Orthophoto — an aerial image processed and geometrically corrected so it can be measured like a map | No | Boundaries, access routes, visual control of the result |
| Drafted drawings | As drafted | The issued drawings the survey office works and reports from |
For a single stockpile, a point cloud of the heap is the shortest path. For a full-site calculation, the three-dimensional surface carries the volumes while the orthophoto defines the limits of work. Per Orion Drone, three-dimensional models and point clouds start from NIS 720, and Orion Drone also performs the processing and drafting of the raw drone material.
Why does the licensed surveyor own the volume figure rather than the drone operator?
A licensed surveyor owns the earthwork volume figure because the license, and not the flight, carries the right to declare it. A licensed surveyor is a holder of a surveying license who is entitled to declare on survey deliverables. Orion Drone supplies drone mapping and survey data to licensed surveyors and survey companies and is not itself a licensed surveyor, so every declaration on a cut-and-fill takeoff belongs to the surveyor who signs it.
This means the volume number is produced in two separable stages. The aerial stage creates measurable material: correct controller settings before take-off, a flight plan that allows good processing afterwards, optional marking and anchoring of control points (GCP) — targets placed on the ground that anchor the image processing — and, where ordered, processing and drafting of the raw drone material into an orthophoto, a point cloud, or a building model. The declaratory stage is where the surveyor evaluates that material against the project's control framework and signs.
| Stage | Who holds it | What it covers |
|---|---|---|
| Flight and data capture | Orion Drone | Pre-flight settings, flight planning, control point marking |
| Processing to deliverable | Orion Drone, when ordered | Orthophoto, point cloud, three-dimensional model from the raw material |
| Verification and declaration | The licensed surveyor | Checking against control, declaring the results, signature |
| Drawing output | The survey company's drafters | Turning the processed material into issued drawings |
By Orion Drone's own account, most of its customers to date are licensed surveyors, and the company states that the aim of the delivery is the highest quality obtainable from the drone, so the licensed surveyor can do their work with it.
How do you brief the flight so the data arrives in time for the earthwork schedule?
A written flight brief is what decides whether the returned data is usable for volume takeoff the day it lands. At the ordering stage — when the cut-and-fill decision is already scheduled and you are committing to a supplier, not still comparing them — the brief is a short document, and these are the items worth fixing in it before anyone plans the sortie.
- Send the site boundary as a file, not a description. A polygon in a standard CAD or GIS format, with a working buffer beyond the earthwork limits, lets the flight be planned directly over your area of interest instead of an approximation of it.
- State the planning context. Say whether the earthwork serves construction planning under a statutory town building plan or a before-and-after measurement checking that the site matches the plans, so the purpose of the flight is clear.
- State the detail level you need. Flight altitude and detail trade against each other: a lower flight yields finer detail but takes longer and costs more, so say whether this is a design-grade survey of a working face or a coarser map of a whole site.
- List the obstructions and access constraints. Cranes, overhead lines, stockpiles, active haulage routes, gate hours and any period the site must be clear of movement all change how the flight is planned.
- Decide who marks the control points. Most surveying firms mark their own; per Orion Drone, marking and anchoring ground control points is available from NIS 180 when you would rather not send a crew.
- Name the deliverables and the decision date. Specify whether you need orthophoto, point cloud, a drawn deliverable, or the raw material for your own processing — and the date the next earthmoving decision falls on.
Schedule slippage in earthwork mapping can often accumulate at the hand-off points rather than in the air, since each unstated boundary, format or obstruction tends to cost a clarification cycle before planning even begins. A licensed surveyor remains the party who signs off on the survey deliverable itself.
Frequently Asked Questions
What should be ordered from a drone flight for earthwork volume takeoff?
A drone flight for earthwork volume takeoff should be ordered together with the deliverables that actually describe the ground surface, because a cut-and-fill calculation is built from surfaces. For licensed surveyors and surveying companies in Israel, that package normally includes a point cloud — a set of three-dimensional points representing the terrain — an orthophoto, which is an aerial image processed and geometrically aligned so it can be measured like a map, and the processing and drafting stage that turns the raw drone material into a workable file. Orion Drone supplies the mapping flight, control point marking, and the processing and drafting of the raw material under one supplier, so the chain does not break between vendors.
When should the before-works and after-works flights be booked?
Earthwork volume takeoff depends on comparing a surface captured before the works with one captured after them, so each flight has to land on the right day in the site programme. Orion Drone states that its response time from order to execution is usually one to three days, compared with the week-to-three-week queue that is common at large mapping companies. For an operations manager holding a crowded job board, that scheduling window is what allows a baseline flight to be fitted in before excavators start moving material, and a closing flight to be fitted in before the site is handed over.
How much ground does a single mapping flight normally cover?
Area size drives both the flight plan and the level of detail in the earthwork deliverable. Orion Drone reports that its average work area on mapping jobs is two to three square kilometres, alongside smaller plots and, at the other end, maps of whole localities over larger areas at a lower level of detail. The governing principle is flight height: the lower the flight, the finer the detail in the product, and the longer and more expensive the flight becomes. A stockpile or a borrow pit calls for a low, detailed flight; a wide site corridor can be flown higher.
Who declares on the survey results?
Only a licensed surveyor — a holder of a surveying licence — is entitled to declare on survey deliverables. Orion Drone is not a licensed surveyor and makes no statement of that kind. What Orion Drone commits to is producing deliverables at the highest quality that can be obtained from the drone, so that the licensed surveyor can do their work on them: correct controller settings before take-off, and a flight plan that allows good processing afterwards. According to Orion Drone, about 80% of its customers to date are licensed surveyors, which is the professional language the service is built around.
Do surveyors have to mark the control points themselves?
Control points, also referred to as GCPs, are points marked on the ground before the drone flight that serve as the anchor for image processing. Most surveyors mark them themselves as part of their own field routine, and that remains the common practice. Where a freelance licensed surveyor or a surveying office is short of field hours, Orion Drone offers marking and anchoring of control points as an add-on service, priced by Orion Drone from NIS 180. Ordering it with the flight keeps the marking and the flight planning in the same hands.
What does a drone mapping job cost to order?
As of 2026, Orion Drone publishes mapping of areas of any size from NIS 540, and three-dimensional models and point clouds from NIS 720. Pricing then follows the flight plan: a lower, more detailed flight over a smaller excavation behaves differently from a high pass over a wide site. Orion Drone also sets its service terms around urgent work — jobs are taken on at short notice, a delay is compensated on the spot, and where the deliverable does not come out as required there is no charge.
