CCART Exposure Layer for India (0.05°), Derived from EMC Built‑up Dataset

Overview This dataset provides the national‑scale exposure raster for India at 0.05° resolution, processed within the CCART (Climate Change Assessment & Risk Toolkit) framework. It represents the built‑up fraction (0–100%) derived from the EarthMap Composite (EMC) Built‑up dataset produced by the Joint Research Centre (JRC), European Commission.

Purpose The exposure layer is designed for climate‑risk modelling applications, including:

static flood risk (FSI × Exposure × Vulnerability)

hazard–exposure–vulnerability integration

district‑level diagnostics

national‑scale risk communication

reproducible open‑science workflows

It is fully aligned with CCART’s hazard grids and FSI products.

Processing Steps (CCART)

Downloaded EMC global built‑up composite

Reprojected to EPSG:4326

Clipped to India national boundary

Resampled to 0.05° resolution

Converted to uint8 (0–100% built‑up)

Assigned 255 as nodata

Verified alignment with CCART FSI grid

Exported as a compressed GeoTIFF

These steps ensure full reproducibility and scientific transparency.
