GIS and Spatial Analysis
Mapping the Path Forward
ICEM applies Geographic Information Systems (GIS), remote sensing, and spatial analysis as core tools across its work in the Asia-Pacific region. These capabilities support a wide range of services, including environmental assessment, climate risk mapping, disaster risk reduction, ecosystem valuation and restoration, infrastructure planning, and integrated river basin management.
With 27 years of regional experience, ICEM combines advanced geospatial technologies with scientific and participatory methods to develop tailored decision-support tools and spatial planning frameworks. From high-resolution mapping and predictive modelling to the design of custom web applications and data systems, ICEM’s geospatial services help clients understand complex socio-ecological systems and prioritize action—from basin-scale planning to village-level land use decisions.

EXAMPLE MAPS
- Disaster risk reduction
Project Description To strengthen its disaster preparedness, the Royal Government of Bhutan (RGoB) launched the Disaster Preparedness Pilot Project (DPPP) in collaboration with the Gross National Happiness Commission, Department of Disaster Management (DDM), and the Swiss Red Cross. Despite a multi-stakeholder approach to disaster risk management, critical gaps remained in contingency planning, emergency response systems, […]
These maps were produced as part of a three-year research program, MK3: Optimising Cascades or Systems of Reservoirs in Small Catchments. The project took place from 2010 and 2013 in two river basins, tributaries of the Mekong – the Nam Theun/Nam Kading in Lao PDR and the Sesan River in Viet Nam and Cambodia, divided into […]
ICEM developed this interactive map of soil types and biochar suitability as part of the ADB-funded Biochar Assessment and Soil Mapping Study. The map allows users to toggle between an in-depth soil map and biochar suitability zones. Users can also zoom in, hover, and click on map elements for more information.
