Digital twin to decision engine: our roadmap
From capture, to intelligence, to foresight — how the platform grows.
Go deep on a subject.
The definitive answer on the questions that decide a project — organised into hubs so you, and the AI answer engines your buyers ask, land on Delta Astra first.
Construction Progress Tracking
How teams move from WhatsApp photos to a measurable, RERA-ready record: capture cadence, as-built vs design, quantities that bill, and evidence lenders trust — with AI progress detection arriving in 2027.
Land & Real Estate Survey
What an aerial land survey actually delivers for developers, plotting ventures and owners — accuracy versus a total station, contours and boundaries, plot visualisation, and the sales-ready views buyers respond to.
Volumetrics & Earthworks
Turning captures into quantities you can certify: stockpile volumes, cut-and-fill against design, overburden and grade verification — repeatable to ±2–3% for inventory, billing and reconciliation.
Digital Twin & Progress AI
What a digital twin is, how it differs from BIM, and where it's going: image processing and computer vision that read a site automatically — the shift from documenting the past to understanding the present.
From record, to intelligence, to foresight.
The resources above document today's platform. Here's the direction every one of them is written toward — the one-stop digital twin that doesn't just show your site, it understands it.
Capture
The measurable twin — exterior and interior, survey-grade, with measurement, CAD overlay and time travel.
Intelligence
Image processing and AI: progress detection, interior component recognition, deviation detection and BIM-vs-reality compare.
Foresight
Schedule-risk prediction, portfolio roll-up and an open API — the one-stop platform for all things digital twin.
