Developer Network

Welcome to the IDL and ENVI Developers Network, a collaborative resource for finding product-related information, submitting code samples and technical tips, forums for communicating with fellow developers, and more. Find what you need below, or contact your IDL Representative >>


Recent Updates

IDL 7.0 Workbench Quick Reference Guide
This quick reference guide will help you get started using the workbench;  Download File >

New Lidar Toolkit
This LiDAR toolkit provides a user of .LAS format LiDAR point cloud data with visualization, analysis and interpretation tools. Also available are an informative web seminar and whitepaper.  View More >

  Code Samples & Plugins

IDLDoc
Produces an HTML documentation system from a library of IDL code. This is similar to the IDL command MK_HTML_HELP, but creates a cross-referenced system of web pages. Special tags can be added to the source code to further annotate the contents of the help.   Download File >>

Spectral Matching Algorithms
This file adds the Normalized Euclidean Distance, Spectral Similarity Mapper, Spectral Information Divergence, SID(SIN), and SID(TAN) algorithms to ENVI's baseline routines.   Download File >>

Lidar Tools
This is a suite of tools for working with raw lidar data in the .las format. Applications allow for clipping, decimating, tiling, or buffering the original data.   Download File >>

Source Code Generator for Beginning IDL Users
Select among a variety of data sources, processing, and visualization options and the Source Code Generator will produce a simple program that does what you want. Each choice comes with a few links to further information in the documentation. You can also run all the programs for testing purposes, and save them for use in your own application.   Download File >>

Tools for Working with RAMAC Ground-Penetrating Radar (GPR) Data
Preprocessing of ground-penetrating radar (GPR) data is often necessary to produce quality images with clearly-visible subsurface features in order to reduce the effects of noise, loss of signal strength with depth, and antenna ringing.   Download File >>

  White Papers

Spectral Mapping Tools from the Earth Sciences Applied to Spectral Microscopy Data
This study explores algorithms originally developed as improvements on early earth imaging techniques that can be easily translated for use with spectral microscopy.   Download Whitepaper >>

Multi-Threading in IDL
Learn about IDL's powerful multi-threading capabilities, which provides a dramatic performance boost when analyzing and processing data on computers with multiple CPUs.   Download Whitepaper >>

Visualizing and Analyzing Medical Images from Multiple Modalities Using IDL
IDL’s powerful visualization and analysis capabilities help you understand medical images from virtually any modality, and integrate custom tools across the health care enterprise.   Download Whitepaper >>

Using ENVI with Geographic Information Systems (GIS)
A major focus of recent and future ENVI development is providing tools to integrate information derived from remotely sensed raster imagery into Geographic Information System (GIS) related applications.   
Download Whitepaper >>

IDL in Java and COM Environments
