Description

fine_tune_final_dataset_freeze_v02_2.zip: YOLOv7 segmentation model

all_training_clean_state_clusters15_t01_wmore.zip:

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
