A drone survey the whole mine can open

The GIS Portal turns drone survey outputs into interactive 3D models a mine can measure — in any browser, with no desktop mapping software and no file handover.

The challenge

A survey that lives in a desktop file is a survey only one team can use.

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.

What the GIS Portal does

Five jobs, all of them in the browser.

01

See the site

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.

02

Measure it

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.

03

Check it against DGMS limits

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.

04

Watch it change

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.

05

Share it safely

Four roles across two organisations. MineGate's team creates sites and uploads surveys; each mining company logs in and sees only its own.

Why it works

Wired into the survey pipeline, not a file dump.

Built for heavy files. Survey outputs land as GeoTIFF, LAS and PDF and are converted by a background pipeline, so a capture measured in gigabytes becomes something a browser can stream.
Speaks GIS. Coordinate systems, terrain tiles and point clouds are handled as real geospatial data, not as pictures of it.
Serves the client directly. The mining companies MineGate flies for log in themselves rather than waiting on an export.

The site renders as an interactive 3D model. Measurement and safety checks run on it directly.

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.

Two sides, one platform

Built for MineGate, and for the mines MineGate flies for.

Backoffice

MineGate's team

Creates a project for each mining site, uploads the outputs from every flight, and manages who on the client side can see what.

Client

The mining company

Planners and safety officers open their own sites, take their own measurements, and run their own haul-road checks. No install, no request queue.

In their words

"The best part? Our planners could open a web browser, access the GIS portal, pull up any mining site, and get a cut-fill volume or a haul-road safety check on the spot. No CAD, no waiting on the GIS team, no file exchange."

This is for you if…

…your site is surveyed by drone and the results still arrive as files.

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.
