The isisdl command is a powerful tool designed for automated downloading of data products and indices from the Integrated Software for Imagers and Spectrometers (ISIS) server maintained by the United States Geological Survey (USGS). It facilitates retrieval of planetary image data crucial for research and analysis, primarily focusing on missions like Voyager, Galileo, Cassini, and Mars Reconnaissance Orbiter. The tool leverages a configuration file (`.isisdl.conf` usually), allowing users to specify download preferences, like the target mission and data types. By managing downloads effectively, isisdl helps researchers acquire and organize large volumes of planetary data for scientific exploration.
Note that isisdl command requires an `.isisdl.conf` file in the home directory, providing credentials for accessing the ISIS archive. It supports various download options and simplifies the process of obtaining planetary science data from the USGS servers. Without proper configuration, isisdl will fail to operate correctly.

Requires a properly configured .isisdl.conf file with valid credentials to access the USGS ISIS archive. Failure to configure this file correctly will result in authentication or access errors. Some data products may require specific permissions or agreements to download.

The .isisdl.conf file typically includes the following information:
- Username: Your USGS username.
- Password: Your USGS password.
- Server: The URL of the ISIS data server.
This file must have the correct permissions (e.g., 600) to ensure security.

After downloading, it's crucial to organize data by mission and product. Consider creating separate directories for each mission and product type to maintain a structured file system. Use tools to verify the integrity of the downloaded files.

isisdl was developed to simplify the process of downloading data from the ISIS archive. Its development was driven by the need to automate and streamline data acquisition for planetary science researchers, reducing the manual effort required to browse and download large datasets. The tool is regularly updated to support new missions and data products available through the ISIS system.
