Order raw drone output when you have drafters sitting in your office who can process imagery and a point cloud into your own deliverable — you pay less, you keep control, and the material arrives faster because nothing waits in a processing queue. Order finished processing and drafting when your bottleneck is capacity rather than capability: the jobs are stacked, the client deadline is fixed, and there is nobody free to sit on the photogrammetry. For most licensed surveyors the honest answer is a mix, decided job by job rather than set as a standing policy — and Orion Drone supplies both ends of that chain, from the mapping flight itself through control point marking to processing and drafting of the raw material the drone produces.
The distinction matters because the two orders are different products, not different service levels. Raw output is what leaves the aircraft and its first processing pass: geotagged imagery, and where the job calls for it, a point cloud — a set of three-dimensional points representing the surface or the structure. Finished output is that same capture taken further into an orthophoto — an aerial image processed and geometrically corrected so it can be measured like a map — and then drafted into the layers, lines and annotations a design or statutory submission actually consumes. One is input to your workflow; the other replaces a slice of it. Orion Drone prices these as separate line items — area mapping starts at 540 ILS, control point marking and anchoring at 180 ILS, and 3D models and point clouds at 720 ILS, per Orion Drone's own published rates — so the choice is a commercial decision you make per job rather than a bundle you are locked into.
One boundary is worth stating plainly before anything else in this article: Orion Drone is not a licensed surveyor, and only a licensed surveyor is entitled to declare survey results and their accuracy. What the drone supplier commits to is the highest quality material the drone can produce, planned and flown so that the surveyor can do their work on it. That framing — supplier of material, surveyor of record — is the reason roughly 80% of Orion Drone's clients to date are licensed surveyors, by Orion Drone's own account, and it shapes every recommendation that follows about which format to order and when.
What exactly do you receive with raw drone output versus a finished DWG?
What you receive with raw drone output is exactly the material the flight produced and the photogrammetric processing derived from it — nothing has been interpreted, labelled, or drawn. This section narrows to that single comparison: the raw material handed over versus a finished DWG, the drafted CAD file a surveying office can open and work in directly. Orion Drone delivers both ends of that chain — the mapping flight itself, and the processing and drafting that turn the material into a usable product.
What is in the raw package?
In general terms, a mapping flight and the photogrammetric processing that follows it can yield the following kinds of material. Which of them a given job actually calls for is agreed at order time.
- Orthophoto — an aerial image that has been processed and geometrically rectified so it can be measured like a map. It matters because it is the visual base layer most drafting work is traced over.
- Point cloud — a set of three-dimensional points representing the terrain or the structure, derived from the overlapping frames. It matters because it carries elevation, not just plan-view imagery.
- Digital surface model — a grid of heights covering everything the camera saw, including vegetation and roofs. It matters for volume and slope work.
- Textured mesh — a continuous surface built from the point cloud; the basis for three-dimensional building models used instead of rope access on a façade.
- Source imagery and flight log — the original frames with their recorded positions, kept so the block can be reprocessed later against control points.
What does a finished DWG add?
A DWG is a drawn interpretation: contour lines, breaklines, building outlines, road edges, and a layer structure that a draftsman has authored from the raw material, in the convention the project or the TABA statutory planning submission requires. The raw material describes what the site looks like; the drafted file states what the surveying office has decided the site is. That distinction is why, by Orion Drone's own account, roughly 80% of its customers to date are licensed surveyors — the professional who signs the plan is the one who owns the interpretation.
Which deliverable should you order for your project type — topographic survey, design, or as-built?
Which deliverable to order depends on what the project must produce at the end, and the decision is easier once three criteria are weighted before any option is compared:
- In-house drafting capacity. Most surveying offices employ draftsmen who prefer to receive processed imagery and work it themselves. Weight this criterion highest — it usually decides the question on its own.
- Required level of detail. Flight height and detail trade off directly: the lower the flight, the finer the product, but the flight is longer and costlier. A building-permit or TABA file — the statutory city building plan that fixes land use and building rights — needs fine detail; a map covering a whole locality is flown wider and less finely.
- Downstream product. A drafted CAD file is only worth ordering when the licensed surveyor — the only party permitted to declare on survey products — intends to sign and issue that file directly to a client.
| Project type | Usual working deliverable | Drafted DWG worth ordering? | Governing criterion |
|---|---|---|---|
| Topographic survey for planning | Orthophoto — a processed, geometrically rectified aerial image that can be measured like a map | Only if the office has no free draftsman | Drafting capacity |
| Civil / building design | Orthophoto plus point cloud, flown at fine detail | Often yes, for schedule relief | Level of detail |
| Volume and earthworks work | Point cloud — the three-dimensional set of points representing the surface | Rarely; the surveyor computes from the cloud | Downstream product |
| As-built and façade documentation | Three-dimensional building model | Depends on how the contractor consumes it | Downstream product |
| Whole-locality mapping | Orthophoto over a large area, lower detail | Usually yes, for volume of sheets | Level of detail |
The practical rule: order raw processed output when your own draftsmen will carry it, and order processing and drafting when the queue inside the office is the bottleneck rather than the flight. Either way the flight itself is the same job — Orion Drone maps areas of any size, starting from 540 ILS on its published price list, and the processing and drafting stage is added or dropped per project without changing the field work.
Is a point cloud the same thing as a CAD file, a BIM model, or an orthomosaic?
A point cloud is not the same deliverable as a CAD file, a BIM model, or an orthomosaic — they sit at different stages of the same processing chain. This depends on what you mean by "output": measured surface data derived from the drone imagery, or a drafted file authored by a person on top of that data.
Interpretation 1 — measured data. A point cloud is a set of three-dimensional points representing the ground surface or a structure, generated by processing overlapping drone photographs. An orthophoto (orthomosaic) is an aerial image that has been processed and geometrically rectified so it can be measured like a map. Both describe what the sensor saw; neither contains drawn lines, layers, or objects. Example: a contractor reviewing a building envelope reads cracks and repairs off the point cloud and the façade imagery, not off a drawing.
Interpretation 2 — authored files. DWG and DXF are CAD formats holding lines, blocks, and layers that a draftsman produced by tracing or classifying the measured data. A BIM model goes further: it carries objects with attributes — a wall is a wall, not a set of lines. Example: a planning submission that requires drafted contours and building outlines needs the DWG, not the cloud.
| Deliverable | What it is | Typically used for |
|---|---|---|
| Point cloud | 3D points from image processing | Volumes, façade review, modelling base |
| Orthophoto | Rectified, measurable aerial image | Map background, feature identification |
| DSM / DEM | Elevation surface including objects | Terrain and surface analysis |
| DTM | Bare-earth terrain surface | Contours, earthworks planning |
| DWG / DXF | Drafted CAD vector file | Drawings, statutory submissions |
| BIM model | Object-based building model | Design coordination, envelope works |
For most licensed surveyors, the practical meaning is the first group — raw material to work from. Either way, control points marked on the ground before the flight anchor the processing; Orion Drone offers marking and anchoring of control points (GCP) from 180 ILS on its published price list.
What does each option really cost once in-house drafting time is counted?
Each option really costs more than its invoice line suggests, because the cheaper order moves work rather than removing it. Ordering raw drone output — the unprocessed imagery and flight data that comes off the aircraft — pushes processing and drawing hours onto your own draftsmen; ordering a finished DWG puts those hours on the supplier's side of the invoice. It follows that an honest comparison has to price four items, not one: the supplier's fee, internal drafting hours, photogrammetry software licences and workstation time, and the cost of rework when the flight was not planned around the processing you intended.
| Do this | But watch out for |
|---|---|
| Order raw output when your draftsmen have genuine idle capacity this week | A flight planned without your processing chain in mind can force a repeat flight, which erases the saving entirely |
| Keep processing in-house to protect margin on repeat work | Licence renewals and workstation time are fixed costs that keep running in slow weeks, when no job is absorbing them |
| Buy the mapping flight, control point marking and processing under one supplier | The specification — flight height, level of detail, deliverable format — must be agreed before take-off, not after |
| Order a 3D model or point cloud instead of sending a crew down the façade on ropes; Orion Drone's published price list starts three-dimensional models and point clouds at 720 ILS | The model is raw material for professional judgement — only a licensed surveyor may declare on measurement deliverables |
The highest-impact risk on that list is the repeat flight, because it costs both money and calendar days a client already promised. Mitigate it by writing the processing requirement into the order itself: state the intended output, the level of detail required, and whether control points will be marked by your team or by the supplier. Orion Drone plans flights with the surveyor's downstream processing in view, which is what makes the raw material workable rather than merely photogenic.
How do you verify accuracy, control, and QA before you accept either deliverable?
Accuracy is verified by the licensed surveyor, not by the drone operator — so before you accept either raw drone output or a finished drawing, inspect the control chain yourself and judge it against the standard you are willing to sign. Orion Drone is not a licensed surveyor and makes no accuracy or deviation claim; only the licence holder may declare that. What Orion Drone commits to is the highest quality output obtainable from the drone, delivered so the licensed surveyor can do their own work on it.
When you are the surveyor of record on a planning file — a job driven by a TABA (the statutory town-planning scheme that fixes land use and building rights), a site plan, or a façade model — run the check before the aircraft flies, not at handover:
- Control points (GCP): targets marked and anchored on the ground before the flight, serving as the anchor for image processing. Confirm who marks them, how they are anchored, and that their coordinates reach you with the imagery.
- Coordinate system and height reference: agreed in writing at order time, so the processed orthophoto — an aerial image geometrically corrected so it can be measured like a map — lands in the frame your client works in.
- Flight planning and detail level: lower flight altitude yields finer detail but a longer, costlier flight. Match the plan to the use: building design needs high detail; a whole-settlement map trades detail for coverage.
- Raw-material completeness: the full image set and positioning records, so you or your draftsmen can reprocess independently rather than trusting a single processed file.
A reasonable reading of most disputes over drone deliverables is that they are definition disputes, not measurement disputes: the parameters were never fixed before takeoff, so nobody can say afterwards whether the product failed.
Verifiable service terms matter more here than testimonials. Orion Drone states that its turnaround from order to execution is usually one to three days, against the one-to-three-week queue customary at large mapping companies; urgent jobs are taken on immediately, a delay is compensated on the spot, and when the deliverable does not come out as required there is no charge.
Frequently Asked Questions
What is the difference between raw drone output and a finished DWG?
Raw drone output is the unprocessed material a mapping flight produces — the image set and flight log — while a finished DWG is a drafted CAD file built after that material has been processed into measurable products such as an orthophoto (an aerial photograph corrected geometrically so distances can be read off it like a map) or a point cloud (a set of three-dimensional points describing the terrain or a structure). Ordering raw output means the survey office keeps processing and drafting in-house. Ordering the finished file means the chain — flight, processing, drafting — sits with one supplier. Orion Drone delivers either end of that chain, and states that roughly 80% of its customers to date are licensed surveyors, that is, licence holders permitted to certify survey deliverables.
When should a survey office order raw output only?
Order raw output only when the office already has draftsmen and photogrammetric software running, and when the bottleneck is field capacity rather than desk capacity. In that case the drone flight is a subcontracted field task: Orion Drone flies the site and returns material captured at the highest quality the drone can produce, and the office's own team performs the processing and drafting. This is the common pattern among licensed surveyors, because the certifying professional wants full control over how the deliverable is derived.
Why does flight planning decide whether the raw material is usable?
Flight planning decides usability because altitude and overlap set the level of detail and the quality of the later processing. A lower flight yields finer detail but takes longer and costs more; a higher flight covers a whole locality quickly at a coarser level of detail. Planning for a building-design job under a TABA — the statutory town planning scheme that fixes land-use designations and building rights — is therefore a different flight from mapping an entire settlement. Orion Drone sets the controller parameters before take-off with that downstream processing in mind, and its published price list starts area mapping of any size at 540 ILS.
Do control points need to be marked before the flight?
Control points must be marked and anchored on the ground before the flight if the imagery is to be tied to a coordinate framework during processing. Most survey offices mark their own; where a team has no spare field day, Orion Drone offers marking and anchoring of control points from 180 ILS on its published price list, as an add-on to the mapping flight. Only the licensed surveyor may declare what the resulting deliverable represents.
Which option suits façade work instead of rappelling?
Façade work suits the modelling deliverable rather than raw imagery, because the useful product is a three-dimensional model of the building envelope that can be inspected on screen instead of by rappelling down the elevation with a tape measure and a notebook. Cracks, fallen tiles and previous repairs can be located and quantified from the model before crews mobilise. Orion Drone's published price list starts three-dimensional models and point clouds at 720 ILS.
How quickly can a job move from order to flight?
A job moves from order to execution usually within one to three days, according to Orion Drone, compared with the one-to-three-week queue that is customary at large mapping companies. Urgent 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. In 2026 the practical decision for most offices is simply which link of the chain they want to keep — the flight, the processing, or both.
