MineGate flies drones over mine sites and turns the footage into 3D survey outputs: orthomosaics — a single stitched, map-accurate image of the whole site — along with point clouds and terrain models.
Those outputs come out of Pix4D, ArcGIS and CAD as large proprietary files. Opening one takes specialist desktop software and specialist skills. So every question about a site had to travel to the one team that had both.
Can the safety officer check this haul-road gradient?
Can our client see this without installing anything?
Can we measure this cut-and-fill without opening CAD?
Every answer meant a file exchange and a wait. The capture was already good; everything after it was the bottleneck.
Orthomosaic imagery, a 3D point cloud — the raw cloud of measured points the drone captured — terrain, contour lines and borehole data, all rendered together in one view.
Distance, surface area and perimeter, stockpile volume, and cut-and-fill — how much material was taken out and how much put back between two surveys. Cross-sections are drawn straight onto the model.
Haul roads are flagged where they run narrower or steeper than the limits recommended by the DGMS, India's Directorate General of Mines Safety. Crest-and-toe and bench analysis — the edges and the working steps of the pit — are checked the same way.
Every flight is kept as its own survey against the site, so a pit can be read month over month on a timeline instead of one snapshot at a time.
Four roles across two organisations. MineGate's team creates sites and uploads surveys; each mining company logs in and sees only its own.

React and TypeScript on the front end with CesiumJS for the 3D view. Python and FastAPI behind it, with PostgreSQL, GDAL and PDAL doing the geospatial work. Storage, queues and delivery run on AWS. Access is one-time-password login plus role-based permissions.
Creates a project for each mining site, uploads the outputs from every flight, and manages who on the client side can see what.
Planners and safety officers open their own sites, take their own measurements, and run their own haul-road checks. No install, no request queue.
The capture is already good. The problem is everything after it — who can open it, who can measure it, and how long that takes. We embed our engineers and build the platform that sits between the survey and the decision.
