Kenya Coastal Zone Boundaries and School Locations

Kenya's coastal zone is mapped in a 1:250,000-scale vector database containing international and administrative boundaries, along with school locations. The database was developed under the Eastern African Action Plan by UNEP/GRID-PAC, UNEP/OCA-PAC, and KEMFRI, integrating data from the Survey of Kenya, Landsat imagery, and socio-economic sources. Feature names and attributes are stored for points, lines, and polygons.

Use Cases

• Analyze school distribution relative to administrative boundaries for educational planning using point and polygon features.
• Model coastal zone management by integrating boundary layers with other thematic coverages like elevation (KEELEVAT).
• Conduct spatial queries on feature names and attributes stored in the vector database's attribute tables.

Strengths

• Database built at a consistent 1:250,000 scale for systematic analysis.
• Integrates data from multiple authoritative sources including Survey of Kenya and Landsat Thematic Mapper.
• Edgematching errors were systematically distributed, with a maximum documented ground error of 750 meters.

Limitations

• Specific row counts, column names, and sample data are unavailable for assessment.
• The temporal range of the data and its last update are not specified.
• Geographic coverage is focused on the Kenya Coastal Zone, not the entire country.

Provenance

Source

Survey of Kenya 1:250,000 series, Landsat Thematic Mapper images, and socio-economic data from Kenyan government ministries and institutes.

Collection Method

Coverages derived from paper maps digitized with control points, satellite imagery, and socio-economic data, followed by manual edgematching.

Geography

Kenya Coastal Zone, with a naming convention extending to other East African countries (e.g., Comoros, Tanzania).
