IDL, the Interactive Data Language, is software for data analysis,
visualization, and cross-platform application development needs. IDL
combines all the tools you need for any type of project, from
"quick-look" interactive analysis and display, to large-scale
commercial programming projects. All in an easy to use, fully
extensible environment.
Interactively perform all your analysis and development in IDL, where
you'll find high-performance processing and an intuitive environment.
o Visualize your data with high-performance image processing,
integrated 2D and 3D graphics, and volume visualization.
o Create leading-edge solutions using IDL's object-oriented
graphics technology.
o Save time with flexible data I/O.
o See results "on the fly" with integrated mathematics and statistics.
o Develop applications quickly with IDL's high-level 4GL and
cross-platform GUI tools.
o Minimize time-consuming code rewrites with versatile program
linking tools.
Fast, Advanced Graphics
-----------------------
IDL software will help you identify subtle relationships and trends
in your data. Easily create and interactively manipulate X-Y and polar
plots, error bars, contours (standard and filled), shaded surfaces, and
mesh surfaces with hidden line removal. Filter out noise to highlight
true data characteristics and expose anomalies. Animate a series of
images for change detection, quality control and pattern recognition.
Explore and manipulate your data like never before with IDL's new
object-oriented, extensible graphic system. Interactively render 3D
images. Spin or fly-through a surface. Shade and illuminate with
multiple light sources. And because IDL's accelerated 3D graphics takes
advantage of OpenGL and other compatible standards, interactive 3D
graphic operations will perform faster than ever before.
Analyze Any Data from Any Source
--------------------------------
Enjoy unparalleled flexibility on large images or multi-dimensional
data with IDL's open architecture. You can read and write virtually
any formatted or unformatted data and handle user-defined and unusual
data formats with ease. We even include specialized support for HDF,
CDF, and netCDF standard formats, as well as data types central to
missions at NASA, JPL, NOAA and other prominent organizations. IDL
supports efficient byte and 16-bit integer data types to conserve
memory and speed processing. Of course, you also have at your disposal:
floating point, double-precision, double-precision complex, and complex
value data types.
IDL Insight - Using IDL is Even Easier
------------------------------------------
You don't have to be an experienced programmer to take advantage of
IDL. You can immediately access common interactive analysis functions
with IDL Insight, a new graphical interface that makes using IDL even
easier. Import data directly into IDL Insight, perform your analysis
and export your results. All with the click of a mouse. You can display,
manipulate and print plots, images and tables, customize menus and
create templates. And maintain command line access throughout your
session.
Mapping
-------
If you work with geospatial or astronomical data, you can chart your
course through fast and accurate analysis with IDL's multitude of
map projections. IDL is the standard software at many major cartographic
and astronomical institutions. And, if your work is highly detailed, a
high-resolution database is included, complete with continents,
coastlines and other geographical information.
Integrated Mathematics and Statistics
-------------------------------------
Conveniently remain in one software environment while you work with
IDL's visual and numerical analysis tools. IDL's mathematics and
statistics libraries -- including industry-standard Numerical
Recipes(TM) algorithms and numerous intrinsic routines -- offer
functions for everything from basic number-crunching and signal
processing to experimental programming. We provide you with a broad
suite of the most useful, exhaustively-tested algorithms for numerical
analysis. These libraries are fully integrated into the IDL language and
included at no extra charge, so you won't waste time and money buying
third-party libraries and integrating them with your programs.
IDL DataMiner - Convenient Database Access
------------------------------------------
Quickly access multiple databases from within a single application
with the IDL DataMiner, a database-independent API that lets you
easily connect, query, modify and extract data from any ODBC-compliant
database system. ODBC (Open Database Connectivity) is the industry
standard for multi-database access. IDL DataMiner lets you combine data
on the fly from a variety of applications and databases for quick,
thorough analyses.
Since IDL DataMiner uses a standardized set of SQL functions, you
don't need to know data structures or be an SQL expert. To make it
even easier, a built-in set of high-level IDL interface routines allow
a database table to be called without writing any SQL statements. The
data called will automatically be converted to IDL data types when
imported. Switching or combining database engines is no problem
either. Just call the appropriate ODBC driver. You can develop on one
engine and port it to another. You can even port the same application
to different engines at different sites. Your ODBC applications are
not affected by new database versions, server changes, or network
transports.
