Treffer: Code for paper 'A satellite-based ice fraction record for small water bodies of the Arctic Coastal Plain'

Introduction This code is used to generate an ice fraction dataset for small water bodies of the Arctic Coastal Plain. It includes code for generating ice fraction in GEE and processing it locally using Python. These codes support the manuscript currently under review: "A satellite-based ice fraction record for small water bodies of the Arctic Coastal Plain". Code Execution Guide Part 1: GEE SectionStep 0: Copy and paste the code from the txt file into the GEE console.Step 1: Collect training samples for the model. Run 1. Sampling (model training).Step 2: Perform hyperparameter tuning of the Random Forest classifier. Run 2. Hyperparameter tuning of the Random Forest classifier (ascending) and 2. Hyperparameter tuning of the Random Forest classifier (descending).Step 3: Export the 1 km ice fraction as CSV files to Google Drive. Run 3. Export ice fraction to Drive (ascending) and 3. Export ice fraction to Drive (descending). Part 2: Python SectionStep 0: Save the ice fraction CSV files downloaded from GEE to data/S1_iceFraction_DESCENDING or data/S1_iceFraction_ASCENDING. Adjust the ascending or descending variables in the code as needed.Step 1: Merge ice fraction CSV files from the same day. Run 1. Merge CSV files from the same day.Step 2: Convert ice fraction CSV files to GeoPackage format. Run 2. Convert ice fraction CSV to GeoPackage.Step 3: Perform post-processing on the ice fraction data. Run 3. Ice fraction post-processing.Step 4: Convert ice fraction GeoPackage to GeoTIFF format. Run 4. Convert ice fraction GeoPackage to GeoTIFF.
