InVEST SDR Model Input Data: Global 1km Resolution Raster Layers

Global raster data layers at a 1 km resolution, prepared as inputs for the InVEST Sediment Delivery Ratio (SDR) model. The dataset includes elevation, precipitation, soil texture, land use, and vegetation cover data sourced from SRTM, ERA5, HWSD, ESA CCI, and MODIS. It was authored by Mingxie Chen and last updated on 2026-04 09.

Use Cases

• Calibrating the InVEST SDR model based on the provided elevation, land use, and precipitation data.
• Analyzing watershed-scale soil loss potential based on the RUSLE equation factors described.
• Mapping sediment connectivity from hillslopes to streams based on the model's spatial logic.
• Assessing the impact of vegetation cover on soil erosion rates based on MODIS NDVI data.

Strengths

• Data is uniformly projected and resampled to a consistent 1 km x 1 km resolution.
• Sources include authoritative global datasets from NASA, ESA, FAO, and ECMWF.
• The dataset is 319.3 MB in size, indicating a substantial but manageable geospatial collection.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Row count and specific column-level documentation are unknown.
• The description does not specify the exact temporal coverage for each data layer.
• Data may reflect the spatial and temporal biases inherent to the original source datasets.
