Better terrain data. Safer communities.

The National Building Research Institute (NBRI) has received a DJI Zenmuse L3 LiDAR sensor as part of an equipment donation through the United Nations Office for Project Services (UNOPS), with financial support from the Government of Australia’s Department of Foreign Affairs and Trade (DFAT).

Why does this matter for Sri Lanka?

Understanding the shape of the land is essential for assessing landslide risk. Mounted on a drone, LiDAR uses laser pulses to create detailed three-dimensional maps. Where pulses reach the ground through gaps in vegetation, it can reveal terrain features that ordinary aerial photographs may miss.

This equipment will strengthen NBRI’s capacity to:

• Map steep slopes, drainage paths and landslide features.
• Support landslide risk assessments and safer settlement planning.
• Provide terrain data for slope stabilisation and drainage design.
• Compare repeat surveys to assess changes in the ground surface.
• Map affected areas to support recovery planning.

Combined with field investigations and expert analysis, these data can help guide decisions to protect communities, roads and other infrastructure.

NBRI gratefully acknowledges UNOPS and the Government of Australia for supporting landslide risk management and disaster risk reduction in Sri Lanka.

🌊✈️ Bridging Land and Water: Integrated DTM Mapping in Action

Precision matters most where land meets water, and that's exactly the challenge our team tackled at the Ma Oya Bambukuliya Water Treatment Plant.

As part of the ongoing Geotechnical Investigation and Riverbank Protection project, the GeoAi LAB (National Building Research Institute - NBRI) has just wrapped up a key survey phase, combining two distinct worlds of datasets into one unified terrain model:

🛩️ Aerial — Matrice 350 RTK equipped with the L2 sensor for high-resolution DTM generation
🌊 Bathymetric — CHCNAV Apache 3 Pro USV for underwater topography
📡 Control — Toknav T30 Pro GNSS receiver for absolute accuracy

A huge shoutout to GIS Solutions Pvt Ltd for executing the bathymetric survey with such precision! 👏

The hardest part wasn't collecting the data but stitching the aerial DTM with the underwater points to create a single, seamless model. We're now leveraging these integrated datasets to generate cross-profiles, perform volumetric calculations, and conduct flood modelling, driving the solution development and detailed design of the riverbank protection.

More updates to come as this data shapes the next phase of the project. 🌏💧

Building Sri Lanka's Landslide Resilience Together

On 3 August 2026, the Inception Workshop for the "Development of the Landslide Resilience Analytical and Advisory System (LA-Res)" project for the National Building Research Institute - NBRI, Sri Lanka, was held at Sheraton Colombo, bringing together a wide circle of national and international stakeholders committed to strengthening Sri Lanka's landslide risk management capacity.

The LA-Res system is being developed for NBRI by the Asian Disaster Preparedness Center (ADPC) as the consulting agency, with funding provided under the Climate Resilience Multi-Phase Programmatic Approach (CResMPA). The initiative aims to strengthen NBRI's and Sri Lanka's technical and institutional capacity for landslide risk assessment and management through a data-driven analytical platform that supports evidence-based decision-making.

The event opened with remarks from Mr Bandula Sirimal (Project Director, CResMPA), Mr Chinthaka Rathnasiri (Director, HSPTD, NBRI), and Mr Aslam Perwaiz (Executive Director, ADPC).

The technical session featured NBRI's presentation on its current systems, infrastructure, and information needs by Dr Dhanushka Jayathilake, followed by presentations from the ADPC team on the project's objectives, the outcomes of the User Needs Assessment, and the proposed LA-Res architecture, components, and applications.

A highlight of the day was the panel discussion on Sri Lanka's climate hazard-risk information landscape, bringing together senior representatives from NBRI, the Department of Meteorology, the Department of Irrigation, and the Disaster Management Centre, followed by an open-floor discussion with all participants.

🌍 The workshop saw strong representation from key national institutions including the Disaster Management Centre, Department of Meteorology, Department of Irrigation, Geological Survey and Mines Bureau, Central Environment Authority, Urban Development Authority, Survey Department, and several line ministries alongside international partners including UNOPS, WFP, UNICEF, UN-Habitat, and the World Bank-funded CResMPA team, reflecting the truly multi-sectoral commitment behind this initiative.

Once operational, LA-Res will give NBRI a single platform bringing together hazard, exposure, vulnerability, and monitoring data supporting faster, evidence-based decisions on landslide risk across Sri Lanka.

Together, we're building a safer, more resilient Sri Lanka. 🏞️

Multi-Stakeholder Kick-off Meeting Marks Launch of LA-Res Project for National Building Research Institute - NBRI

On 17 July 2026, the Multi-Stakeholder Kick-off Meeting held at Waters Edge, Battaramulla marked the formal launch of the "Development of the Landslide Resilience Analytical and Advisory System (LA-Res)" project for the National Building Research Institute (NBRI), Sri Lanka.

The LA-Res system is being developed by the Asian Disaster Preparedness Center (ADPC) as the consulting agency, with funding provided under the Climate Resilience Multi-Phase Programmatic Approach (CResMPA). The initiative aims to strengthen Sri Lanka's technical and institutional capacity for landslide risk assessment and management through a data-driven analytical platform that supports evidence-based decision-making.

The event brought together senior representatives from NBRI, CResMPA, the Ministry of Agriculture, Livestock, Lands and Irrigation, the Disaster Management Division (MoD), ADPC, the Department of Irrigation, the Department of Meteorology, GSMB, CEA, and the Disaster Management Centre.

Opening remarks were delivered by Eng. (Dr) Asiri Karunawardena (Director General, NBRI), Mr Bandula Sirimal (Project Director, CResMPA), and Dr Peeranan Towashiraporn (Director, Risk Analytics and Climate Services, ADPC), all emphasizing the national importance of a unified landslide information platform.

NBRI subsequently presented an overview of its existing systems, infrastructure, operational challenges, and information system requirements related to landslide risk management. The presentation was delivered by Dr Dhanushka Jayathilake, Senior Scientist, NBRI, followed by ADPC's presentation on project scope, timeline, and inception-phase activities.

The interactive discussion session gave stakeholders a chance to share how landslide data supports their institutional mandates — and how they envision using LA-Res in their day-to-day operations.

🌍 Once operational, LA-Res will integrate hazard, exposure, vulnerability, and real-time monitoring data into a single platform — enhancing situational awareness, anticipatory action, and decision-making at national and district levels.

Together, we're building a safer, more resilient Sri Lanka. 🏞️

The GeoAi Lab has completed detailed damage assessment reports for landslides across Kandy, Matale, Kegalle, Badulla, Nuwara Eliya, and Kurunegala districts, following requests from NBRI District Offices, the Road Development Authority, and Sri Lanka Railways.

Between 22 November 2025 and 15 May 2026, our team conducted LiDAR and photogrammetry drone surveys using DJI Matrice 350 RTK, LiDAR L2 sensor, DJI Mavic 3M, and Toknav T30 Pro GNSS, and the assessments completed up to that date have been compiled into reports.

The reports provide comprehensive insights including:
✅ Incident details and damage boundaries
✅ Number of fatalities and injuries
✅ Fully and partially damaged buildings
✅ Landslide profiles (spatial, longitudinal, cross-sectional)
✅ Economic losses at site and district levels

These assessments help authorities plan recovery efforts, improve risk management, and strengthen disaster preparedness for the future.
