1995 data depicts the fraction of each 5-minute by 5-minute grid cell equipped for irrigation across Africa. The map was created by the CEOS_EXTRA organization, combining statistical data on irrigated areas within administrative units with geographical information on their locations.
Use Cases
- Analyze the fraction of irrigated land per grid cell to model historical agricultural water demand.
- Combine administrative unit irrigation statistics with point, polygon, and raster location data for spatial validation.
- Use the 5-minute cell resolution to assess regional patterns of irrigation infrastructure development in the mid-1990s.
Strengths
- Spatial resolution of 5-minute grid cells (approximately 9.25 km x 9.25 km at the equator).
- Data integration from multiple sources: administrative statistics and geographical location data in point, polygon, and raster formats.
Limitations
- Data is temporally stale, representing a snapshot from around 1995.
- Specific row counts, column names, and sample sizes are unknown.
- The dataset's geographic scope is limited to the African continent.
