Measure difficult-to-reach structures without unnecessary access equipment.

Media4You uses the DJI Matrice 4T laser rangefinder to capture remote height, distance and area measurements alongside high-resolution visual evidence — useful for planning, estimating, inspection support and access decisions.

Subject to site conditions, weather, airspace, target visibility and the agreed measurement purpose. This service is not a substitute for a certified land survey or fabrication-grade dimensional survey.

Get useful dimensions before committing to scaffolding or machinery.

Some jobs need a dimension long before they need physical access. A roof height, façade width, chimney position, clearance or industrial asset dimension may be enough to price work, plan access, order the right equipment or decide whether a closer inspection is worthwhile.

Using the Matrice 4T, Media4You can capture the measurement and the visual context together. That means the client receives more than a number: they can see exactly what was measured and where the measurement came from.

• Safer initial assessmentReduce unnecessary work at height where remote measurement is suitable.
• Faster informationObtain key dimensions without waiting for temporary access solely to take an initial measurement.
• Reduced disruptionA short planned drone operation can minimise interference with normal site activity.
• Clear visual evidenceMeasurements are supplied with annotated imagery so the client can see the points or area being referenced.
• Access planningUse dimensions and imagery to help select the correct scaffold, MEWP, ladder system or other access method if one is still required.

Heights, distances and areas from a viewpoint that is difficult to reach from the ground.

Vertical heights

Building elevations, chimneys, roof features, tanks, masts and other clearly identifiable points.

Point-to-point distances

Distances between visible features, edges, fixtures and structural reference points.

Horizontal or sloped lengths

Approximate spans, roof runs, façade sections and other visible line measurements where geometry and visibility are suitable.

Areas

Visible façade sections, roof sections, ground areas or other clearly defined polygons using the aircraft's supported area-measurement tools.

Target locations

Record and communicate the location of a feature or point of interest for follow-up inspection or site work.

Tick what you need, then add it to your enquiry.

Need stockpile volumes rather than area measurements? Stockpile Measuring

From a measurement list to clear results in four steps.

1. 1

   Tell us what needs measuring

   Send the site address or postcode, photographs if available, the dimensions you need and what the figures will be used for.

2. 2

   We review and plan the flight

   Media4You checks airspace, access, hazards, target visibility, weather requirements and whether laser measurement is appropriate for the requested tolerance.

3. 3

   Capture and measure

   The Matrice 4T is positioned to obtain clear sight of the agreed targets. Measurements and supporting imagery are captured during the operation.

4. 4

   Receive your results

   You receive the agreed measurements with annotated images, a simple summary and any relevant limitations. A branded PDF report can be included where required.

Illustrative example: the named lines show the requested opening and height measurements, not recorded project results.

What the system enables.

Meet the fleet

Useful across buildings, construction and industrial sites.

Illustrative example: hatch width, route length and walkway clearance for rooftop access planning.

• Roofs & chimneys

  Check heights, approximate dimensions and the position of visible roof features before arranging access.

• Façades & buildings

  Measure building heights, sections, setbacks and visible external features for planning and estimation.

• Access planning

  Help establish the height and reach required before booking scaffolding, a cherry picker or other access equipment.

• Industrial assets

  Measure visible tanks, silos, structures, pipe runs and equipment clearances where the target can be safely observed.

• Signage & external fixtures

  Record approximate sizes and mounting heights for signs, lights, antennas, cameras and external equipment.

• Site clearances

  Check visible distances between structures, access routes and overhead or elevated features to support site planning.

• Property & maintenance estimates

  Provide contractors with useful dimensions and photographs before they prepare a quote or decide what access is required.

Choose the level of reporting your job actually needs.

Illustrative example: ridge, chimney and eaves measurements with the reporting outputs a client can receive.

Measurement schedule

A list of agreed dimensions, clearly named and presented in metres or other agreed units.

Annotated photographs

Images showing the measured points, line or area so the figure has visual context.

Site overview imagery

High-resolution photographs showing the wider asset, structure or area around the measurement.

Branded PDF report

Optional professional report combining the measurement schedule, annotated images, capture date, scope and limitations.

Additional visual inspection imagery

Where agreed, zoom or thermal imagery can be captured during the same operation when it is useful and appropriate to the job.

Repeat measurement

Return visits can be arranged where the same feature needs to be checked again or where work is being completed in stages.

Deliverables are agreed before flight. CAD-ready dimensional surveys, engineering certification and legal boundary work are not included unless separately scoped with an appropriately qualified professional.

Useful remote measurement — with the limitations stated clearly.

The Matrice 4T laser rangefinder is designed for real-time measurement and supports functions including PinPoint, line drawing and area calculation. It is well suited to planning, estimating, inspection support and access decisions where a practical remote dimension is required.

Those figures are the manufacturer's rangefinder specification, not a guarantee that every derived height, line or area measurement will achieve the same tolerance. Practical results also depend on the target, viewing angle, reflectivity, weather, aircraft position and how clearly the measurement points can be identified.

DJI published laser distance specification

At distances above 3 m, DJI specifies distance measurement accuracy as ±(0.2 + 0.0015 × D) metres, where D is the measurement distance in metres.

10 m target distance:

approximately ±0.22 m

50 m target distance:

approximately ±0.28 m

100 m target distance:

approximately ±0.35 m

Suitable for

• Planning and estimation
• Access planning
• Inspection support
• Approximate asset dimensions
• Contractor pre-quotation information
• Visible height, distance and area checks

Not positioned as

• Fabrication-grade measurement
• Legal boundary determination
• Certified land surveying
• Structural engineering certification
• Millimetre-tolerance dimensional control

Need tighter accuracy?

If your project needs tighter positional accuracy or a formal survey deliverable, tell us before booking. We can determine whether a separate photogrammetry/mapping workflow is more appropriate or whether an independent qualified surveyor should be involved.

Weather

DJI states that laser rangefinding performance may degrade in rain or fog.

Extended site measurement

Includes extended on-site capture, multiple measurement targets and a more detailed reporting package. Final scope is agreed before booking.

Additional / quoted items

A drone does not replace scaffolding or a MEWP in every situation. The service is most valuable where the client needs measurements or visual evidence before deciding whether physical access is necessary.

Frequently asked questions.

How accurate are the measurements?

The Matrice 4T laser rangefinder has a published distance accuracy specification of ±(0.2 + 0.0015 × D) metres beyond 3 m. The accuracy of a final height, line or area measurement also depends on target visibility, viewing angle, weather and how precisely the measurement points can be identified. We state the intended use and relevant limitations before the job is confirmed.

Can this replace a land survey?

No, not by default. This is a remote aerial measurement service for planning, estimating, inspection support and similar commercial decisions. If you need a certified topographic survey, legal boundary work or engineering sign-off, tell us before booking.

Can you measure a roof without anyone going onto it?

Often, yes, where the required points are visible and the flight can be carried out safely and legally. We review the exact requirement before confirming the job.

Can you measure the height of a building or chimney?

Yes, where the relevant top and reference points can be clearly identified and the site allows a suitable measurement geometry.

Can you measure an area as well as a distance?

Yes. The Matrice 4 Series supports line drawing and area calculation as part of its laser rangefinding workflow. Suitability depends on the shape and visibility of the target.

Can you calculate stockpile volume with this service?

Not from the laser rangefinder alone. Stockpile volume is handled through Media4You's dedicated photogrammetry-based Stockpile Measuring service.

Do I still need scaffolding or a cherry picker?

Possibly. The service can remove the need to hire access equipment solely to obtain an initial dimension or visual check, but any physical work, close inspection or repair may still require appropriate access equipment.

What happens if the weather is poor?

We will only fly when conditions are suitable for a safe operation and useful data capture. DJI also notes that laser rangefinder performance can degrade in rain or fog.

What do you need from me for a quote?

A site address or postcode, photographs if available, a list or sketch of what needs measuring, the intended use of the figures and your preferred timeframe.

Tell us what needs measuring.

A site location, a few photographs and a simple list of the measurements you need are usually enough for us to start reviewing the job.
