# Rebulk > Rebulk is the operating system for bulk materials. It combines volumetric inventory measurement (fixed LiDAR sensors, phone scanning, and drone capture) with rail and transload operations software (railcar tracking, bills of lading, waybills, scale tickets, demurrage, and customer reporting) in one connected platform. Rebulk serves transload terminals, rail-served warehouses, plants, quarries and aggregate yards, grain and feed operations, biomass and carbon-removal companies, and other facilities that store and move bulk materials. ## Products - [Bulk Inventory System](https://rebulk.com/products/bulk-inventory-system): Continuous, automated inventory measurement for stockpiles, sheds, bays, and yards using fixed LiDAR and camera sensors, mobile phone capture, and drone capture — all writing to one inventory record per pile. - [Transload Operating System](https://rebulk.com/products/transload-operating-system): End-to-end terminal workflow — inbound BOL/waybill processing with AI extraction, railcar and inventory tracking, scale tickets, demurrage, and customer reporting. - [Railcar Management Software](https://rebulk.com/products/railcar-tracking): Track every railcar by spot, contents, owner, and status; storage-day and demurrage billing; built for the facility side of rail (terminals, plants, rail-served warehouses) rather than fleet management. ## Guides - [The Best Ways to Measure Stockpile Volume in 2026](https://rebulk.com/blog/best-way-to-measure-stockpile-volume): Honest comparison of walk-around estimates (±20–40%), phone scanning apps (within a few percent, one lap around the pile), drone photogrammetry (1–2% with ground control), fixed LiDAR (continuous), and survey services — with a verdict per use case. ## Services - [Drone Capture](https://rebulk.com/services/drone-capture): One-off and scheduled drone stockpile surveys. - [Deployment Services](https://rebulk.com/services/deployments): Field installation of LiDAR, cameras, and edge devices. ## Company - [Technology](https://rebulk.com/technology): How Rebulk measures — sensor capture, AI processing, volumetric modeling. - [Customer Stories](https://rebulk.com/customer-stories): Including Charm Industrial (biomass carbon removal) and a large US dairy feed provider. - [Contact](https://rebulk.com/contact): Demo booking.
