IDL : The Interactive Data Language

Access Virtually Any Type of Data

IDL provides built-in support for the data sources, data types, file formats, and file sizes you use. Use IDL to access common formats like TIFF, JPEG, PNG, and hierarchical scientific data formats like HDF, HDF-EOS, CDF, and netCDF, as well as custom binary and ASCII formats. And, because IDL is designed for large, multi-dimensional data, no job is too complex. Receive data from remote servers or write files to a disk at a remote location using common protocols. IDL acts as a client to HTTP and FTP servers, and provides access to common Open Geospatial Consortium (OGC) servers such as Web Map Service (WMS) and Web Coverage Service (WCS).

Intuitive Rules and Conventions

The IDL language is based on rules and conventions that are intuitive and easy to learn, regardless of the languages you’ve used before, or even if you have no programming experience at all. Using IDL you can create visualization programs and even full-blown applications with fewer lines of code. With an extensive library of prebuilt analysis and visualization routines, IDL is the choice for programmers of any experience level.

Dynamic Type System

IDL is a dynamically typed language – meaning you can change variables and values at runtime rather than creating new variables and values, recompile, and then re-execute your code, as is required with a static language. The dynamically typed nature of IDL gives you more flexibility in your programming, which saves you valuable time and allows you to focus on data analysis and visualization, rather than on programming details.

Integrate With Other Applications  

IDL is a flexible and extensible language that supports two-way interaction with other applications, including those developed in C, C++, Java, Visual Basic, and more. Get the most from your existing code by easily calling other applications from IDL, or calling IDL into other applications.

Flexible Development Features  

IDL makes developing easier than other languages. Quickly develop small programs or large applications using time-saving features like content assist, auto complete, color coding, and hover help. And, code templates make creating your, plots, graphics, and other visualizations easier than ever.

Share Your Programs and Applications  

IDL allows you to share your small program or full application code with colleagues who use IDL. For runtime distribution of applications to users who do not own an IDL license, IDL Virtual Machine is a no-cost option to run compiled IDL programs. In situations where the developer requires greater flexibility, IDL runtime licensing is available.

IDL : GRAPHICS SYSTEM

Produce insightful graphical visualizations of your complex numerical data quickly and easily with the IDL graphics system. With its intuitive syntax, the IDL graphics system gives you the flexibility to create high-quality graphic visualizations to help interpret your data and share results with colleagues.


Easily Create High-Quality Graphics

IDL Quality Graphics

The scriptable nature of IDL makes it easy to quickly create powerful graphic visualizations, ranging from 2D plots, contours, maps, and image displays to complex, interactive 3D representations. The powerful IDL graphics engine leverages OpenGL hardware acceleration for rapid rendering. This means IDL can efficiently handle large data sets and output the graphics you need.

Customize Individual Graphic Attributes

IDL Custom Attributes

The interactive IDL graphics system allows you to customize how your graphics look. Whether you need to include multibyte characters (Japanese, Chinese, or Korean) or include TeX-like formatting for math and Greek annotations, IDL is suitable for creating graphics for office presentations or international publications. While other programming languages require you to reprogram or regenerate results to make a change, with IDL you can modify line styles, symbols, annotation, font style, and color on the fly.

Output to Virtually Any Image File Format

IDL Image Formats

Programmatically or interactively output to a variety of standard image formats, like GIF, JPEG, PNG, TIFF, EPS etc. or import graphics into PowerPoint, Keynote, or HTML presentations. Additionally, graphics can be output to PostScript or PDF for inclusion in a journal article, LaTeX, or Word Document. With so many standardized output options, you can easily share your findings with colleagues for review, secondary analysis, or a verification study.

IDL : CAPABILITIES

Image Processing

If you need to convert raw images to information, IDL contains an extensive library of image processing and analysis routines. IDL allows you to extract useful information from nearly any type of digital image with tools for transforming image geometry, mapping, masking and statistics, warping, analyzing regions of interest, and contrasting and filtering.

Signal Processing

IDL has advanced tools for processing signal data, including transforms for signal decomposition, windowing algorithms, routines for smoothing, convolving and applying digital filters to remove noise, and correlation and covariance techniques to analyze signals with random components. IDL also has a built-in wavelet toolkit that provides GUI and programmatic wavelet analysis of multi-dimensional data.

 

How Can We Help?

The image above is an example that utilizes IDL’s autoencoder neural network for unsupervised classification on an image which creates a reusable classifier that can then be applied to different datasets.

Machine Learning

Data analysis has never been easier with access to machine learning algorithms in IDL. Create classifiers using neural networks, Softmax, Support Vector Machine (SVM), K-Means and autoencoders. IDL allows you to read in data from virtually any format and classify it with machine learning algorithms. Advanced users can even use the IDL-Python bridge to access TensorFlow or Keras to further extend your IDL applications.

The graphic above shows the locations of particles in a physics simulation and tracks the total energy over time. With visualizations like these, IDL makes it easy to verify the behavior of complex algorithms or models and, with temporal datasets, allows you to easily export the results as animations.

Math and Statistics Routines

The IDL Advanced Math and Stats Module is an addon solution for when you need to quickly add advanced mathematical and statistical functionality to an IDL application. It combines advanced data visualization and analysis capabilities with the comprehensive mathematical and statistical routines of the IMSL™ C Numerical Library – a set of pre-written mathematical and statistical algorithms that can be embedded into your program.
