RSI IDL 6.3

RSI IDL (Interactive Data Language) is a high-level, array-oriented programming language and interactive environment designed for scientific data analysis, visualization, and application development. It is widely used to manipulate large numerical datasets, generate publication-quality graphics, and build custom analysis tools with concise, expressive code.

Key capabilities:

• Array-first language with vectorized math for fast numerical computing
• Extensive 2D/3D visualization, including plots, contours, surfaces, and volume rendering
• Built-in image and signal processing libraries
• Native support for common scientific data formats (e.g., FITS, HDF5, NetCDF, GeoTIFF, CDF)
• Cross-platform support on Windows, macOS, and Linux
• Extensibility via dynamically loadable modules and interfaces to C/Fortran; Python integration is available
• Integrated development tools, including the IDL Workbench, debugger, profiler, and the IDL Virtual Machine for distributing run-time applications

Typical uses:

• Astronomy and astrophysics data reduction and visualization
• Remote sensing and geospatial analysis (often paired with ENVI)
• Medical imaging and signal processing
• Space physics, atmospheric, and climate research

RSI IDL is commercial software and typically requires a license, though the IDL Virtual Machine enables end users to run packaged applications without a development license.
