Setup and Installation Process

To get started with TorchGeo, follow these simple installation steps:

git clone https://github.com/microsoft/torchgeo.git
cd torchgeo
pip install -e .

Ensure you have the necessary dependencies installed. You can find the complete list of requirements in the requirements.txt file.

Usage Examples and API Overview

Once installed, you can start creating datasets and running experiments. Here’s a quick overview of how to create datasets:

Creating Datasets

To create datasets, you can use the provided scripts:

bash sample_30.sh  # for TM, ETM+, OLI/TIRS
bash sample_60.sh  # only for MSS
bash sample_conus.sh  # for benchmark datasets

Modify the user-specific parameters in the scripts to customize your dataset creation process.

Downloading Data

After sampling locations, download the data using:

bash download_mss_raw.sh
bash download_tm_toa.sh
bash download_etm_toa.sh
bash download_etm_sr.sh
bash download_oli_tirs_toa.sh
bash download_oli_sr.sh

These scripts allow you to specify various parameters such as ROOT_DIR and SAVE_PATH for data management.
