Walking Travel Time to Health Centers in Malawi at 100m Resolution

A 100-meter spatial resolution geotiff of walking travel time in seconds to the nearest health facility in Malawi. The data was generated using the Child Poverty and Access to Services (CPAS) software and created as part of the CPAS project within the Data for Children Collaborative. It uses the GCS_WGS_1984 projection system and was last updated on March 9, 2026.

Use Cases

• Modeling healthcare accessibility based on walking travel time to Level IV facilities.
• Identifying underserved regions for health infrastructure planning based on travel time surfaces.
• Integrating travel time data with population or poverty maps for vulnerability analysis.

Strengths

• 100-meter spatial resolution provides detailed geographic granularity.
• Travel time is calculated for walking speeds across roads, tracks, paths, and land cover types.
• Data is openly licensed under CC-BY-4.0.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
