ID | Variables | Definition |
|---|---|---|
1 | \({\rm{i}}\) | 10 km grid cell |
2 | \({\rm{j}}\) | Crop type |
3 | \({\rm{k}}\) | Administrative unit |
4 | \({\rm{y}}\) | Year |
5 | \({{Prob}}_{{ijy}}\) | Probability of crop type \({\rm{j}}\) in grid \({\rm{i}}\) in year \({\rm{y}}\) predict by RF. |
6 | \({{PixelArea}}_{i}\) | Pixel area in grid \({\rm{i}}\), factor that transforms proportion (0-1) into area (ha). |
7 | \({{Stat}}_{{jky}}\) | Area Statistics (ha) of crop type \({\rm{j}}\) in administrative unit \({\rm{k}}\) in year \({\rm{y}}\). |
8 | \({{AdjProb}}_{{ijy}}\) | Adjusted probability of crop type \({\rm{j}}\) in grid \({\rm{i}}\) in year \({\rm{y}}\) in the process. |
9 | \({{Cropland}}_{{iy}}\) | Cropland area proportion in grid \({\rm{i}}\) in year \({\rm{y}}\). |
10 | \({{Crop}{Intensity}}_{{iy}}\) | Harvest frequency in grid \({\rm{i}}\) in year \({\rm{y}}\). |
11 | \({{MaxHarvArea}}_{{iy}}\) | Maximum of harvested area in grid \({\rm{i}}\) in year \({\rm{y}}\). |
12 | \({{\rm{HarvAreaL}}{\rm{eft}}}_{{iy}}\) | Left harvested area space where crop statistics can be allocated in grid \({\rm{i}}\) in year \({\rm{y}}\). |
13 | \({{LeftCrop}}_{{iy}}\) | List of crop types whose statistics have not been allocated when the maximum harvested area is achieved in grid \({\rm{i}}\) in year \({\rm{y}}\). |
14 | \({{\rm{StatLeft}}}_{{jky}}\) | Statistics of crop type \({\rm{j}}\) which has not been allocated in administrative unit \({\rm{k}}\) in year \({\rm{y}}\). |
15 | \({{\rm{CropArea}}}_{{ijy}}\) | Harvested area of crop type \({\rm{j}}\) in grid \({\rm{i}}\) in year \({\rm{y}}\) |
