PRELIMINARY SATELLITE-DERIVED FLOOD AND LANDSLIDE ASSESSMENT for South Africa Rivers

A satellite-derived assessment of flood and landslide impacts along several rivers in South Africa as of April 2022. The dataset was produced by the United Nations Satellite Centre (UNOSAT) and is available in SHP and GEODATABASE formats. It likely contains geospatial features documenting inundated infrastructure, damaged roads, and landslides.

Use Cases

• Map inundated infrastructure based on observations of flooded oil refineries and roads.
• Monitor river water level changes based on reported increased water levels along multiple rivers.
• Assess landslide risk and location based on observations along the Palmiet river.
• Analyze flood extent and damage to transportation networks based on descriptions of damaged roadways.

Strengths

• Produced by a authoritative organization, the United Nations Satellite Centre (UNOSAT).
• Available in standard geospatial formats (SHP, GEODATABASE) for interoperability.
• Focuses on a specific event with observations dated 14 April 2022.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
