PIMA Adapta Costas Viewer

Visualizes and analyzes coastal risks associated with climate change on the Catalan coast

The PIMA Adapta Costas Viewer is an interactive tool developed by the ICGC (National Commission for the Conservation of Natural Resources) that allows the visualization and analysis of coastal risks associated with climate change along the Catalan coast.

The PIMA Adapta Costas project is an initiative of the Ministry for Ecological Transition and the Demographic Challenge, within the framework of the National Plan for Adaptation to Climate Change.

The ICGC developed the viewer for Catalonia, and the Catalan Office for Climate Change was responsible for the project in Catalonia.

The viewer is aimed at land managers, urban planners, researchers, and policymakers who need accurate data for decision-making regarding coastal management and climate change adaptation. It is also useful for citizens interested in understanding the potential impact of climate change on coastal areas.

The viewer covers the entire coast of Catalonia and provides detailed information on marine flooding and erosion in eight specific areas..

Data and techniques

High-resolution geospatial data, digital terrain models, climate projections, various cartography, and predictive models that consider different climate change scenarios were used to develop the viewer.

For more information, see the Report on Risks on the Catalan Coast in the Face of Climate Change (PIMA Adapta Costas project) (Catalan).

Formats, visualizations and interactive features

The viewer offers interactive consultation of different information layers structured in six tabs: Introduction, Coastal Observation, Delimitation, Variables, Scenarios and Risks. The layers are originally shapefiles. The loaded data produced by the ICGC is in vector tile format for optimal visualization. The viewer incorporates the Mapbox GL JS library, which uses WebGL to render interactive vector tile maps. The background cartography, both topographic and hybrid orthophotoimagery, are products of the ICGC for Catalonia and of OSM for the rest of the world (also based on the vector tile structure).

The main screen of the viewer contains the main components of the application and is almost entirely occupied by the map view (main work area).

Below is a view of the viewer with the identification of the main components:

The ICGC worked on the project from 2018 to 2022 and currently maintains the viewer with project information.
