EFG F3.3 Rice paddies – current maps
F3. Artificial wetlands biome
This page provides information about the valid indicative distribution map for the ecosystem functional group F3.3 Rice paddies. For older or alternative maps, see here.
Methods
Here is the methods summary for Map code and version: F3.3.web.alt v2.0.
The distribution of rice paddies was estimated from the percentage of rice cover at a 5 arc minute resolution based on Monfreda et al. (2008). Cells with > 10% rice cover were designated as major occurrences, and those with 1-10% rice cover were designated as minor occurrences.
Datasets
Anthromes-v2.0 (Monfreda CN, Ramankutty N, Foley JA 2008):

Processing
Processing steps used in this map are: Thresholds.
Map evaluation
This map is considered to be a Medium quality map series based on the following characteristics:
Concept alignment is Direct,specific.
Ground observations are NA.
The accuracy evaluation Quantitative accuracy assessment,documented,quantitative.
