Shape file used to train Random Forest model. The polygons labeled as Fish Pond are the manually annotated ponds. Columns are:
| ids | Unique identifier of object. |
| state | State where the object is located |
| geometry | Polygon geometry |
| split | train/test/valid split |
| Fishpond | True label, 1: Fish Pond, 0: No Fish Pond |
| area | area of the prediction in meters |
| length | perimeter of the prediction in meters |
| inv_isoper | isoperimetric ratio: how round is the prediction, 1 for circle |
| ave_r | average of red color for prediction |
| ave_g | average of green color for prediction |
| ave_b | average of blue color for prediction |
| std_r | standard deviation of red color for prediction |
| std_g | standard deviation of green color for prediction |
| std_b | standard deviation of blue color for prediction |
