Irrigation-equipped land fraction is mapped for the Middle East at a 5-minute by 5-minute grid cell resolution (approximately 9.25 km x 9.25 km at the equator). The dataset was created by the CEOS_EXTRA organization, combining statistical administrative data with geographical information on irrigated areas. It represents a snapshot of irrigation infrastructure from around 1995.
Use Cases
- Analyze historical irrigation fraction per grid cell to model regional water demand.
- Compare irrigation infrastructure density across administrative units within the Middle East.
- Use the gridded fraction data as a baseline layer for land-use change studies over time.
Strengths
- Spatial resolution of approximately 9.25 km x 9.25 km per grid cell.
- Data synthesis from multiple sources including statistical reports and geographical records.
Limitations
- Temporal coverage is limited to a single snapshot circa 1995, making it outdated for current analysis.
- Specific row and column counts, sample size, and original file formats are unknown.
Provenance
- Source
- CEOS_EXTRA via NASA Earthdata.
- Collection Method
- Derived by combining statistical data on irrigation area within administrative units with geographical information (point, polygon, raster format).
- Time Range
- circa 1995
