Geospatial services for the projects that build India.

A drone survey captures a site from the air and turns that capture into measurable data. Instead of walking the ground with instruments, one flight records the whole area at a known accuracy, and processing converts it into an orthomosaic, a point cloud, a terrain model and contours. You measure from a single consistent dataset rather than stitching separate visits together.

Ground control points are surveyed across the site first. The aircraft then flies a planned grid at a height chosen for the ground sample distance your tolerance needs, recording positions with RTK or PPK correction. Processing ties the imagery or laser returns to that control, classifies the data, and writes the outputs to your coordinate system.

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

Per-acre pricing is misleading on its own, because a hundred acres of open ground and a hundred acres of forested slope need different sensors, different flight heights and very different processing effort. We quote on the full scope instead. Area matters, but so do accuracy tolerance, terrain, vegetation and how many times you need the site flown.

Accuracy is a method rather than a number we can promise before seeing a site. With RTK or PPK positioning and surveyed ground control, results are reported against independent checkpoints held out of processing, so you receive the accuracy actually achieved instead of an advertised figure. The control and checkpoint report is attached to every handover.

That is set by what the data will be used for, not by a general rule. Earthwork quantities, drainage design and setting-out each carry their own tolerance, and the flight is planned backwards from whichever is tightest. Tell us the tolerance your design needs and the mission is built to meet it, then checked against it.

For large or awkward sites, usually yes. A corridor is long and thin, which is the worst shape for ground survey and the best for aerial capture. One mobilisation covers tens of kilometres at consistent accuracy, and repeat flights turn earthwork claims into measured quantities rather than estimated ones. For a very small flat plot, conventional survey can still be simpler.

Drones need airspace clearance, they are affected by weather, and photogrammetry alone cannot see the ground through dense vegetation. The last one is the most common surprise on Indian sites. Where canopy blocks the view we fly LiDAR instead, which records multiple returns per pulse so bare earth can be classified out from vegetation.

A total station gives higher accuracy on an individual point. A drone survey gives good accuracy across every point at once, which is usually what a design needs. On most infrastructure sites the two work together: ground instruments establish the control network, and the aerial capture is tied to it and checked against independent points.

Processed outputs rather than a folder of raw images. Typically an orthomosaic as GeoTIFF, a classified point cloud as LAS or LAZ, a terrain model as DEM or DTM, contours as DXF, volume reports as CSV or PDF, and a 3D mesh as OBJ where it is useful. The control and checkpoint report ships alongside them.

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 on arrival.

Field time depends on the area and the sensor, and processing depends on how much classification the site needs. Rather than quote a general figure, we commit to a delivery date in writing when we quote. Progress-monitoring clients receive their deliverable on a fixed monthly cycle so the programme can plan around it.

Yes. Scope and permissions are step one of the process. Airspace clearance and site permissions are handled before mobilisation, and the pilots are DGCA-certified, which is the documentation a public tender asks to see. On restricted sites this step drives the programme, so it is worth starting the conversation early.

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, so the data does not leave the people responsible for it between capture and delivery.

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. The method does not change with the country: control is established, capture is tied to it, and independent checkpoints report what was achieved.

Ask three things. Can they show named projects with named clients rather than stock imagery. Do they report accuracy against independent checkpoints, or only advertise a figure. And is processing done in-house, since a subcontracted pipeline is where accountability and data control usually break down. Ask for the control report from a past job.

Neither. The same team plans the mission, flies it and processes the result. That matters for accountability, because when a quantity is questioned there is one team that can explain the control, the checkpoints and the classification behind it. It also means project data is not handed to another company.

A normal aerial photo has perspective distortion, so distances measured on it are wrong. An orthomosaic is corrected for terrain and camera geometry and tied to a coordinate system, so it behaves like a map. You can measure directly on it, and it overlays correctly on your existing drawings and GIS layers.

Yes, and it is one of the most common requests. Progress work flies a saved mission repeatedly so each dataset aligns with the last, which turns a series of site visits into a measurable time series of quantities. Live sites need the flight planned around cranes, working areas and the day's activity.

The site boundary, the approximate area, the accuracy your design needs, and the deliverables you expect. A KML, shapefile or even a marked-up map is enough to start. If you are unsure about the accuracy figure, tell us what the data will be used for and we will work backwards to the tolerance.
