Solutions

Drone survey and mapping services, end to end

Eight capabilities, one field team. Every mission is planned to the accuracy your design needs and processed in-house, so the file that reaches your engineers is the file they can work from.

01 · Drone Survey & Mapping

Drone survey and UAV mapping

The full survey, from flight planning and ground control to the file your engineers open.

A drone survey replaces weeks of walking a site with instruments. One flight captures the whole area at a known accuracy, so you measure from a single consistent dataset instead of stitching together separate visits.

Missions are planned to the ground sample distance the deliverable needs, flown with RTK or PPK positioning, and tied to surveyed ground control points. Checkpoints held back from processing are used to report the accuracy actually achieved, not the accuracy hoped for.

02 · Topographic & Land Survey

Topographic survey, contour survey and DGPS land survey

Contours and terrain models on your datum, with the control report that proves them.

A topographic survey records the shape of the ground: levels, breaklines, contours and existing features. Design, drainage and earthwork all start from it, so an error here propagates through every downstream quantity.

DGPS-grade control is established across the site and the aerial capture is registered to it. Ground is classified out from vegetation and structures before contours are generated at the interval you specify, then delivered in your EPSG code and units.

03 · Photogrammetry & Aerial Mapping

Photogrammetry and aerial mapping

High-overlap imagery processed into measurable orthomosaics and 3D models.

Photogrammetry turns overlapping aerial photographs into measurable geometry. It is the right tool for open ground, stockpiles, construction sites and anything where you need a true-colour base map you can measure directly.

Flights are planned for consistent forward and side overlap at 1 to 3 cm ground sample distance. Tie points and ground control drive the bundle adjustment, producing an orthomosaic, a dense point cloud and a textured mesh from the same capture.

04 · LiDAR Survey

LiDAR survey and aerial laser scanning

Ground level under vegetation, where photogrammetry alone returns canopy.

LiDAR pulses find gaps in vegetation and record returns from the ground beneath it. On forested ghat sections, reservoir slopes and overgrown corridors it is the only aerial method that gives a true bare-earth surface.

Multiple returns per pulse are classified into ground, vegetation and structure. The classified ground class becomes the terrain model. We flew this method for Central Railway across two ghat corridors and for EDF Energy at the Sawale hydro project.

05 · Hydrographic & Water Survey

Hydrographic survey and bathymetric mapping

One continuous surface across the waterline, above it and below it.

Water projects need the bed and the bank in the same model. A reservoir capacity study, a drainage design or a dredging quantity all depend on a surface that does not break at the shoreline.

Aerial capture covers the land and the exposed bank. Bathymetric data covers the submerged bed. The two are merged on a common datum into one continuous terrain model, so volumes compute across the full extent without a gap at the waterline.

06 · GIS & Data Processing

GIS services and geospatial data processing

Classification, QA and delivery into the GIS, CAD and BIM platforms your team already runs.

Raw capture is not a deliverable. The value is in the processing: classifying the cloud, checking it against control, structuring the layers and handing over something that opens correctly on the first try.

Processing runs in-house. Nothing is subcontracted and project data is not passed to a third party. Output is written to your EPSG code, datum and layer convention, so it drops into your existing project structure rather than needing rework.

07 · Inspection & Monitoring

Drone inspection and construction progress monitoring

Repeat flights on a fixed path, so month two is comparable to month one.

Monitoring only works if the captures are comparable. Flying the same path at the same height on a schedule turns a series of site visits into a measurable time series of progress and quantities.

Progress flights repeat a saved mission so each dataset aligns with the last. Thermal capture adds defect detection on solar fields and electrical assets. We run this pattern monthly for L&T across the Navi Mumbai Airport build.

08 · Project Films & Aerial

Project aerial films and corporate video production

Aerial photography and films of the project, shot by a crew that already flies it for survey.

Project media for boards, tenders, investors and milestones. The same crew that flies the survey knows the site, the airspace clearance and the safe lines, so a media capture does not start from zero.

Capture is planned around the construction sequence so the shot list matches what is actually built that month. Delivered as graded 16:9 masters with vertical crops for internal and social use.

How we work

From permissions to deliverables, handled end to end.

Five steps, the same on a 60 km corridor and a single site. Nothing is subcontracted.

  1. 01

    Scope and permissions

    We confirm the area, the accuracy spec and the deliverable list, then handle airspace clearance and site permissions.

  2. 02

    Control and flight plan

    Ground control is laid across the site and the mission is planned to the ground sample distance your tolerance requires.

  3. 03

    Field capture

    A two-person crew flies the mission with RTK or PPK positioning, with checkpoints surveyed independently.

  4. 04

    Processing and QA

    Processing, classification and checkpoint review run in-house, against your stated tolerance.

  5. 05

    Delivery in your formats

    Point clouds, terrain models and contours arrive in your EPSG code and file types, with the control report attached.

By sector

The same capabilities, tuned to your project type.

A solar park and a forested hydro slope need different sensors and different flight plans. Pick your sector to see how the work changes.

FAQ

Questions buyers actually ask

If your question is not here, ask it in the enquiry form and a surveyor will answer it.

What does a drone survey cost?

Cost follows scope rather than a rate card. The drivers are the area, the accuracy tolerance you need, the sensor the site demands (photogrammetry or LiDAR), how much ground control is required, the number of repeat visits, and the deliverable list. Send us the site boundary and your accuracy spec and we will come back with an approach and a quote within one business day.

How accurate is a drone survey?

Accuracy is a method, not a number we can promise before seeing the site. With RTK or PPK positioning and surveyed ground control, our deliverables are reported against independent checkpoints held out of processing, so you receive the accuracy actually achieved rather than an advertised figure. The control and checkpoint report is attached to every handover.

When do I need LiDAR instead of photogrammetry?

Use photogrammetry on open ground where you want a true-colour base map you can measure. Use LiDAR where vegetation blocks the view of the ground, such as forested ghat sections, reservoir slopes and overgrown corridors. LiDAR records multiple returns per pulse, so ground can be classified out from canopy. On mixed sites we fly both and merge them.

What formats do you deliver in?

GeoTIFF for orthomosaics, LAS or LAZ for point clouds, DXF for contours and linework, DEM and DTM for terrain, OBJ for meshes, and CSV or PDF for volume reports. Everything is written to the EPSG code, datum and units you specify, so it opens directly in your CAD and GIS without reprojection.

Do you handle drone permissions and airspace clearance?

Yes. Scope and permissions are step one of the process. We handle airspace clearance and site permissions before mobilisation, and our pilots are DGCA-certified, which is what public tenders ask to see.

How long until we receive deliverables?

Turnaround depends on area, sensor and the classification effort a site needs. We commit to a date in writing when we quote, and progress-monitoring clients receive their monthly deliverable on a fixed cycle so the programme can plan around it.

Can you work outside India?

Yes. Crews mobilise to site internationally, and we also process data captured by a local team to the same accuracy standard and deliver it in your formats.

Who owns the data?

You do. Project data stays with our team under clear handling terms for the duration of the work and is not passed to a third party. Processing runs in-house rather than through a subcontractor.
