Paper DOI Code DOI Data DOI

Code for the publication:

Stachelek, J., Avendaño, S., Schwenk, J., 2022. Geographically aware estimates of remotely sensed water properties for Chesapeake Bay. Journal of Applied Remote Sensing. https://doi.org/10.1117/1.JRS.16.044528

Products

Setup

Software

conda env create -f environment.yml

Data

  • Locate the observational data file all_data.csv (download from figshare if necessary)

  • Sync its path with the location defined in data/params.csv

Usage

Generate training data

# the following chunk executes scripts/00_get_data.py
make data_aggregated_gee_csv
# manually upload aggregated_gee.csv to GEE
# manually download results to data/unique_pixeldays_w_bandvals.csv
make data_aggregated_w_bandvals_csv

# add freshwater influence predictor
make data_w_fwi

Train RF model

# variable selection + initial fitting
make data/X_train_salinity.pkl

# hyperparameter tuning
make data/rf_random_salinity.pkl

Pull prediction data

python scripts/03_get_data_predict.py --date "2022-09-04"

Generate prediction surfaces
