Delta Astra offers the OpenSpace-style core — interior 360° walkthroughs pinned to floor plans, with time travel across dates — and adds what a survey-led platform brings: survey-grade exterior mapping, CAD overlays and a full measurement toolset, with India-first support and RERA-friendly reporting.
The parity part
If you know OpenSpace, the interior experience will feel familiar: walk the floor from a browser, jump between capture dates at the same spot, pin field notes, and share with stakeholders. That's table stakes and Delta Astra delivers it.
Where Delta Astra goes further
Delta Astra is built survey-first, so the exterior is genuinely measurable — orthomosaics, terrain, cut-and-fill and stockpile volumes — and CAD/design overlays sit on top. You get interiors and a survey-grade exterior in one platform, not two vendors.
Built for India
Local support, RERA-friendly reporting, and pricing and workflows suited to Indian developers and infrastructure agencies — plus a 2026 roadmap into AI progress detection and image processing.
Key takeaways
- Interior walkthroughs, pinning and time travel — on par
- Adds survey-grade exterior mapping and measurement
- CAD and design overlays in the same platform
- India-first support, RERA-friendly, with an AI roadmap
