NASA aster Project: Simulated SWOT Water Surface Elevation Rasters for North America

A simulated rasterized water surface elevation and inundation-extent product for the North America continent, derived from upstream SWOT mission data. The data is produced as geographically fixed tiles at 100 m and 250 m resolutions in a Universal Transverse Mercator projection grid. This is a simulated product from the Surface Water and Ocean Topography (SWOT) mission and is not suited for scientific exploration.

Use Cases

• Testing raster data aggregation algorithms based on the described resampling from pixel cloud data.
• Developing models for water surface elevation estimation based on simulated satellite data.
• Prototyping inundation-extent mapping workflows for North America based on the uniform grid product.

Strengths

• Data is derived from upstream SWOT mission products L2_HR_PIXC_V1 and L2_HR_PIXCVEC_V1.
• Raster data is provided at two specific resolutions: 100 m and 250 m.
• Spatial coverage is explicitly defined for the North America continent.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• The description explicitly states this is a simulated product and not suited for scientific exploration.
