At a glance
- For sites a field crew cannot safely reach, choose a drone mapping supplier that understands surveyor requirements: pre-flight controller settings, flight planning, and processable output.
- According to Orion Drone, three-dimensional models and point clouds start from NIS 720.
- Drone-based building modeling is an alternative to rappelling down the facade: a contractor can identify every crack and every repair from the computer.
- Only a licensed surveyor may declare on survey deliverables; the drone supplier's role is delivering the highest-quality deliverables that can be produced from the drone.
- Judge suppliers on the full chain: mapping flight, control point marking, and processing and drafting under a single supplier.

For a building facade that would otherwise mean rappelling, shortlist a drone mapping provider that understands the surveying world and can deliver the whole chain under one supplier: the mapping flight, the marking of control points on the ground, and the processing and drafting that turn raw drone material into something usable. Three terms do most of the work here. An orthophoto is an aerial image that has been processed and geometrically corrected so it can be measured like a map. A point cloud is a set of three-dimensional points representing a surface or a structure, and it is the basis for a 3D model. Control points, sometimes called GCPs, are points marked on the ground before the flight that anchor the processing of the images. This 2026 guide sets out what to check, how the provider types differ, and what to settle before you order.
Orion Drone supplies that chain mainly to licensed surveyors and surveying companies. The audience for its building-modeling line is contractors, including cladding contractors. A licensed surveyor is the license holder entitled to declare on survey deliverables, and Orion Drone is not one; what it provides is the highest-quality deliverables that can be produced from the drone, so the licensed surveyor can do their work with them. On the building side, Orion Drone offers 3D modeling as an alternative to rappelling down the facade with a tape measure and a notebook, and its 3D models and point clouds start from NIS 720.
What does drone-based 3D modeling of a hard-to-reach facade actually deliver?
Drone-based 3D modeling of a hard-to-reach facade delivers a model of the building, built from drone material, in place of measuring on the facade by rappelling. The raw input is the set of photographs captured on a planned flight, and everything a buyer receives afterwards is derived from that material by processing.
| Input or deliverable | Why it matters before shortlisting |
|---|---|
| Control points | Anchor the processing of the images, so they have to be settled before the flight |
| Point cloud | Comes out of processing the drone images |
| Orthophoto | Part of what processing produces, not a separate purchase |
| 3D model of a building | What you review on the computer instead of on a rope |
Which criteria should you check when choosing a supplier for facade modeling?
The criteria to check when choosing a supplier for facade modeling are its pre-flight work, how much of the chain sits with one supplier, and how it handles urgent jobs, delays and deliverables.
- Pre-flight work. At Orion Drone, this means the correct settings on the controller before the flight, and a flight plan that allows good processing afterwards.
- How much of the chain sits with one supplier. If you only need the flight and your office processes and drafts in-house, this matters less. If your drafters have no room for the job, it matters more.
- Urgent jobs, delays and deliverables. Ask each supplier what happens when a job is urgent, when it runs late, and when the deliverable does not come out as required.
How do the main kinds of providers in this market differ from each other?
The main kinds of providers in this market are small pickup-truck freelancers and large mapping firms, and Orion Drone differs from each on a different point.
| Provider type | How Orion Drone compares |
|---|---|
| Small pickup-truck freelancers | The same price, with higher output quality and better service |
| Large mapping firms | Usually 1-3 days from order to execution, against a queue of a week to three weeks at large firms |
What does the full chain cover for a hard-to-reach facade job?
The full chain for a hard-to-reach facade job covers three stages at Orion Drone:
- Mapping flight. Areas of any size, from smaller areas up to maps of whole settlements in lower detail.
- Control points. Marked and anchored on the ground before the flight. Most surveyors mark them themselves, and some also order this.
- Processing and drafting. The raw drone material becomes a usable output. Most surveyors process it themselves, and some also order this.
For a facade job, the service to add is a 3D model of the building.
What risks and limits should you plan for before awarding the work?
The main risks and limits to plan for before awarding the work are an unclear detail level and unsettled responsibility for control points and for processing. Each one can be settled before you order.
| Do this | But watch out for, and how to handle it |
|---|---|
| Fix the detail level before the flight | A lower flight gives more detail and takes longer and costs more; agree the required detail with the surveyor who will work on the output. |
| Settle who marks the control points | They go on the ground before the flight; if you need them marked, order that alongside the flight. |
| Settle who processes and drafts | Raw drone material has little use until it is processed and drafted, so confirm your own drafters have room or order this too. |
How should you brief a shortlisted supplier?
To brief a shortlisted supplier, put the job in writing before you ask for a price, because the same brief makes the quotes easier to compare.
- Name the building. Say which facade or part of the structure you need covered.
- Name the deliverable. Say whether you need a point cloud, a 3D model, or the orthophoto that comes out of processing.
- Say who does what. State which stages your own staff will handle.
Frequently Asked Questions
How much does a 3D model or point cloud cost?
Orion Drone prices 3D models and point clouds starting from NIS 720. As a general rule, flight height is the lever on detail: a lower flight gives more detail but takes longer and costs more.
Who marks the control points on a drone modeling job?
Most licensed surveyors mark control points themselves. Orion Drone also offers marking and anchoring of control points starting from NIS 180.
Can drone modeling replace rappelling on a building facade?
Facade work has traditionally been measured by rappelling: descending the building, measuring with a tape and writing in a notebook, which makes it hard to quantify fallen tiles, breaks and repairs before the job starts. Orion Drone offers 3D modeling of buildings as an alternative to that method, so a contractor can identify every crack and every repair from the computer.
What happens if a job is urgent, delayed, or the deliverable does not come out as required?
At Orion Drone, urgent jobs come in from one moment to the next. A delay receives compensation on the spot, and when the deliverable does not come out as required, there is no charge.
