Sectors
Survey built around the project, not around the drone
A corridor, a runway, a forested reservoir slope and a salt-flat solar park each need a different sensor, flight plan and deliverable. Here is how the work changes across the eight sectors we fly.
Flying survey-grade missions in India
Mapped across corridors, sites and catchments
Enterprise and government projects delivered
Survey-grade aircraft in the fleet
01 · Highways
Highway and expressway corridor survey
A corridor is long and thin, which is the worst shape for ground survey and the best shape for aerial capture. One mobilisation covers tens of kilometres at a consistent accuracy, and repeat flights turn earthwork claims into measured quantities.
Flown for NHAI across highway works, and for Sterlite Power along a 200 km transmission corridor.

02 · Airports
Airport construction and runway survey
Airport sites are large, flat and tightly toleranced, and they sit inside controlled airspace. The survey has to be planned around clearance and around an apron that changes shape every month.
Monthly progress reporting flown for L&T across the Navi Mumbai Airport build.

03 · Ports
Port, quay and coastal survey
Port work needs the land and the water in one dataset. Stockpiles move weekly, haul roads get set out against existing ground, and the survey has to hold up when quantities are certified.
Haul road setting-out survey delivered for Adani Ports at Dighi Port.

04 · Hydro-electric
Hydro-electric project and reservoir survey
Hydro sites combine steep slopes, dense canopy and water. Photogrammetry alone returns treetops rather than ground, which is the wrong surface for penstock alignment or reservoir capacity.

05 · Solar parks
Solar park topography and thermal survey
Solar sites look flat and are not. Small level changes decide the grading quantity and the module table layout, and once the park is live, thermal capture is the fastest way to find underperforming strings.
Topography survey delivered for Aditya Birla Renewables at a solar park in Kutch.

06 · Real-estate construction
Real-estate and township construction survey
Developers need progress they can show and quantities they can certify. A monthly flight gives both from one capture: a measured model for the project team and clean visuals for sales and investors.
Delivered for Embassy Group, BL Kashyap and Reliance Group projects.

07 · Government & public
Government and public infrastructure survey
Public work is documented work. The deliverable has to arrive with the control report, the accuracy statement and the pilot certification that a tender review will ask for, in the format the department specified.
Delivered for NHAI, NHSRCL, Central Railway and NHPC.

08 · Mining & energy
Mining, quarry and energy asset survey
Stockpile volume is money, and a monthly walkover measures it badly. Aerial capture measures the whole pile geometry at once, and the same flight updates haul road and bench survey.
Delivered for Tata Power, Torrent Power and Takalkar Power assets.

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.
