Could we see floods 🌊 evolve on streets in immersive 3D before damage happens?

📰Our new paper published in CEUS led by Dr. @rohan_debayan introduces a 4D geospatial flood digital twin to address this challenge: https://t.co/j9dhRhkAye

Our first Colloquium lecture of the semester was electric! ⚡

From mapping energy transitions, strengthening resilience in 4D, to satellite imagery prediction — we covered it all. A big thank you to our faculty guest speakers Debayan Mandal, Salma Elmallah, Heather Baier and to all attendees!

Stay tuned for our next Colloquium happening on Friday, Oct. 10 with #SGSUP Instructor Kaelin Groom.

Assistant Teaching Professor Debayan Mandel recently attended and presented at the International Cartographic Conference (ICC) in Vancouver.

His presentation, "Advancing Urban Flood Preparedness with 4D Geospatial Digital Twins" highlighted how digital twin technology can strengthen disaster resilience and urban planning.

ICC was a great networking opportunity that brought together delegates from across the globe, offering new perspectives on cartographic innovation in diverse cultural and institutional contexts.

🏗️ GIS-BIM Integration: Managing Infrastructure Beyond Handover

In many infrastructure projects, design and construction get all the attention — but what happens after commissioning often determines the true value and resilience of that asset.

This is where GIS-BIM integration becomes a game-changer: it brings spatial intelligence into the entire lifecycle of a building or infrastructure asset — from operations and maintenance to long-term planning and upgrades.

Imagine this:

🔹 You’re managing a public hospital. With GIS-BIM, you can spatially locate every MEP system, oxygen line, and access route. Maintenance doesn’t just follow schedules — it follows spatial logic.

🔹 In a university, you track underground cables, fire systems, or CCTV coverage in real-world coordinates, layered with surrounding land use, future development plans, or risk zones.

🔹 For county governments, you can monitor building stock — schools, dispensaries, admin blocks — not just in isolation, but how they relate to terrain, flood zones, road networks, or land tenure.

Instead of flipping through PDFs or CAD drawings, facility managers and planners can interact with a spatially intelligent model — seeing what’s where, what’s failing, and how surrounding conditions are changing.

This goes beyond reactive maintenance.

With GIS-BIM:

- Work orders are tied to specific locations and systems

- Emergency response becomes spatially guided

- Infrastructure upgrades align with regional development plans

- Asset depreciation and lifecycle costs are tracked with geographic awareness

- Cities and counties can begin to build true infrastructure digital twins

Why it matters:
We’re moving from managing assets in silos to managing spatially-aware infrastructure ecosystems. GIS-BIM bridges not just systems, but disciplines — planning, engineering, facilities, and policy — all working from the same geospatial canvas.

This is what smart infrastructure actually looks like — connected, contextual, and coordinated.

👷‍♂️ At @OrionGeospatial, we work with public and private clients to bring GIS-BIM integration into real-world infrastructure and facility operations. From spatial asset mapping to lifecycle planning tools, we help you build, operate, and maintain smarter.

📩 Let’s talk if you're rethinking how infrastructure should work — not just at design, but for decades after handover.
