Improvement: Check and Save Preprocessed Image FilesIn this little comment, I want to add a feature that checks if the preprocessed image files already exist in the specified directory before saving new ones. This ensures that we do not perform redundant operations and only save images if they are not already present. Problem DescriptionWhen processing satellite images, it is essential to avoid redundant operations such as re-saving images that have already been preprocessed. This can save time and computational resources. SolutionTo handle this situation, we can use a function to check if the preprocessed image files already exist in the specified directory. If the files do not exist, the script will save the images; otherwise, it will skip this step. Improved Codeimport os
# Function to check if jpg files already exist
def check_files_exist(path, file_extension=".jpg"):
if not os.path.exists(path):
return False
return any(file.endswith(file_extension) for file in os.listdir(path))
# Define the path to preprocessed jpg files in the current directory
preprocessed_path = f"./data/{sitename}/jpg_files/preprocessed"
# Check if directory exists and if files exist
if not os.path.exists(preprocessed_path):
os.makedirs(preprocessed_path)
print(f"Directory created: {preprocessed_path}")
if not check_files_exist(preprocessed_path):
# Only save images if they don't already exist
SDS_preprocess.save_jpg(metadata, settings, use_matplotlib=True)
print("Satellite images saved as .jpg in", preprocessed_path)
else:
print("Preprocessed jpg files already exist in", preprocessed_path) Explanation
This improvement ensures that the script efficiently handles preprocessed image files, avoiding unnecessary reprocessing and saving of files. |
Purpose : Authentication Script for Google Earth EngineThis script is designed to test the connection to Google Earth Engine (GEE) before running example Python scripts. It ensures that the authentication to GEE is successful, allowing further operations with GEE to proceed smoothly. Before executing any Earth Engine scripts, it is crucial to verify that the authentication to Google Cloud is working correctly. This script handles the authentication and initialization process, providing feedback on whether the authentication was successful or not. Script:
