Johns Hopkins Applied Physics Lab IDL Web Page.
This site contains some of the best examples of IDL programs, in a variety of categories. I wouldn't think of writing a new IDL program unless I checked here to see if it had already been written. Be sure to download the catalog of one-line program descriptions.

IDL Astronomy Library World Wide Web home page.
This site is a general repository of general purpose IDL astronomy routines. If you are looking for a routine to read FITS files, this is the place to start. You can browse through a list of one-line descriptions and download the files directly.

Craig Markwardt's IDL Library
This site is fast becoming my "go to" site when I am looking for interesting code. The curve fitting routines Craig offers are superiour to the ones that come with IDL, and there is an excellent curve fitting tutorial here, as well. In addition, you will find some of the best array manipulation routines to be found anywhere on the web. The routine CMSET_OP for performing set operations (intersection, union, and exclusive OR) is great, as is CMAPPLY, a program that can flexibly perform almost any mathematical operation on an array or a portion of an array. You owe yourself a look at this site.

Liam Gumley's IDL Web Page at the University of Wisconsin.
Liam is another person who has become a major programming resource in the IDL community. You will find a number of useful screen capture and color handling programs on this site. But I often send folks here for his satellite image mapping tool, IMAGEMAP. This is the only program I know that takes satellite image pixel data, with corresponding latitude and longitude coordinates, and places them on a map projection. You will also find a nice HDF browser for looking as SDS data sets. Have a look.

Ben Tupper's IDL Library
Ben showed up in one of my IDL programming courses a long time ago and it was immediately obviously he was going to be a wonderful IDL programmer. There was something about the bleary eyes, disheveled look, and eager manner that recalled my own introduction to IDL. If you are looking for information on how to convert to UTM map coordinates or if you need access to the 5.5 On-Line Help that RSI conveniently forgot to include in that version of IDL, have a look at this site. Ben was the only inductee into the IDL Expert Programmer's Association in the year 2000, a particularly lean year. :-(

Mark Hadfield's Motley IDL Library
Mark has been doing some interesting work with IDL object programming. You can find some of his utility routines as well as some nifty object classes on this site. In particular, have a look at his MGHgrGraph code for a simple X-Y graph object. There are methods for for adding axes, plots, annotations etc. The most convenient thing about it is that atoms added to the graph automatically have their scaling adjusted to fit the axes. Check out his MGHgrAnimator object for animating a sequence of object graphics pictures. You will also find tools for working with netCDF files among the programs in this excellent collection.

University of Washington Astronomy World Wide Web home page.
This site is notable for containing on-line help for over 3000 IDL procedures and functions written by users all over the world. In addition, you will find an excellent tutorial by Eric Deutsch on how to produce pretty PostScript output.

Rob Dimeo's IDL Web Page at the NIST Center for Neutron Research.
Rob is an excellent IDL programmer who understands curve fitting inside and out. Here you can find DAVE (Data Analysis and Visualization Environment), an integrated environment for the reduction, visualization and analysis of inelastic neutron scattering data. One of the most interesting pieces of DAVE is a general purpose curve fitting program with a graphical user interface, named PAN, which can be downloaded separately. You can also find a neat little widget program that allows you to solve the Schrodinger equation in one dimension using the discrete variable approximation. Well worth having a look.

Martin Schultz's IDL Web Page at Max-Planck-Institut f黵 Meteorologie .
Martin is a regular contributor to the IDL newsgroup and is frequently offering his well-written programs. The highlight of his site is his EXPLORE software, which is a widget based tool for interactive data analysis. Many other IDL routines are also available. The site has recently (September 2000) been updated and now includes searchable links to the best IDL libraries on the Internet. A great place to go if you want to see what is out there and available.

Robert Dahni's IDL Web Page in Melbourne, Australia.
Robert is a long-time IDL user at the Bureau of Meteorology in Melborne, Australia. He has been instrumental in organizing IDL user groups in Australia. Robert has done an excellent job of organizing extensive IDL web resources, especially those of interest to meteorologists. His Resources page is a must-read for those looking for coast and shoreline data sets.

JD Smith's IDL Benchmark Page
Are you thinking about purchasing a new computer? Or do you wonder how your computer measures up against the competition when running IDL? If so, then check JD's page out. He has the latest information about benchmark specs for a variety of computers running IDL. While you are there, take a couple of minutes to add your computer's information to the database. JD makes it easy to submit your results.
