OpenDragon: New Open-Source Imagery Analysis Program

The Global Software Institute announces that their Open Dragon software, a variant of Goldin-Rudahl’s Dragon/ips software for aerial/satellite imagery analysis, is now freely available for non-commercial use, and the Java source code will be released as open source sometime in the near future. From their press release:

OpenDragon offers a full suite of image analysis and raster GIS capabilities including image enhancement, supervised and unsupervised classification, geometric correction, measurement and statistics, vector capture and display, slope, aspect and buffer calculations and multi-criterion decision making. Open Dragon also includes the Open Dragon Toolkit, which allows users who can program in C to extend the software functionality. GSI will also make the source code for OpenDragon available for non-commercial use under an Open Source license during the next six to nine months.

Installation is currently kind of a pain – you have to register for a key code just to download the software, and then unzip all files to a directory. The setup program in the main directory doesn’t create the program directory but requires you to select one, so you should create that (and a Temp directory) before starting program installation. Registration requires an internet server connection that the program seems to have trouble establishing; this process will supposedly be simplified in the near future. And, at least under Windows 7, running the program downgrades the color scheme to Windows 7 Basic for some unknown reason; first time I’ve seen this with a Java program. No uninstall listing added, either, though with Java software just deleting the program directory and icons is usually good enough.

A full PDF manual is included with the installation package.
