The OpenJPEG library is an open-source JPEG 2000 library developed in order to
promote the use of JPEG 2000.
The main part of the project consists in a JPEG 2000 codec compliant with the
Part 1 of the standard (Class-1 Profile-1 compliance).
Besides this main codec, OpenJPEG integrates several other modules:
- JP2 (JPEG 2000 standard Part 2 - Handling of JP2 boxes and extended multiple
component transforms for multispectral and hyperspectral imagery)
- MJ2 (JPEG 2000 standard Part 3)
- JPWL (JPEG 2000 standard Part 11)
- JPIP (JPEG 2000 standard Part 9)
- OPJViewer, a GUI viewer for J2K, JP2, JPWL and MJ2 files

OpenJUMP is an open source GIS software written in Java. It is based on
JUMP GIS by Vivid Solutions. It's features include:
* It is a Vector GIS that can read rasters as well.
* OpenJUMP is known to work on Windows, Linux and Mac platforms, but
should work on any operating system that runs Java 1.5 or later.
* It is not just another free demo viewer, but you can edit, save,
analyze etc. with JUMP / OpenJUMP.
* It works, even with medium size datasets, and with professional
touch.
* It provides a GIS API with a flexible plugin structure, so that
new features are relatively easy to develope around the sound
mapping platform.
* It utilises standards like GML, WMS and WFS.
* It is already translated in English, Finnish, French, German,
Italian, Portugese and Spanish. The translation in other languages
is in progress.
Extensions and plugins can be found at
A Perl/GTK application that lets you draw ASCII charts using a GUI. Objects on
the screen are sizable and have all the properties you'd expect in a drawing
tool (titles for the boxes, bullets, etc), but the end result is plain text
that's embeddable in your code.
Deegree iGeoPortal is the web-based portal framework of deegree. It
offers visualization of geodata through a standard web browser like
Mozilla, Firefox or MSIE.
Optar stands for OPTical ARchiver. It's a codec for encoding data on
paper, then you print it with a laser printer. If you want to read the
recording, scan it with a scanner and feed into the decoder program.
OptiPNG is a PNG optimizer that recompresses image files to a smaller
size, without losing any information. This program also converts
external formats (BMP, GIF, PNM; TIFF support is coming up) to optimized
PNG, and performs PNG integrity checks and corrections.
The idea has been inspired from pngcrush, and is explained in detail in
the PNG-Tech article "A guide to PNG optimization". The implementation
is carried forward in OptiPNG, which offers a faster execution per
trial, and a wider search space.
The Open Scene Graph is a cross-platform C++ OpenGL library for the
real-time, photo-realistic rendering of large 3D models. Uses range from
visual simulation, to scientific modelling, to games, to whatever you can
think of!
osgEarth is a C++ terrain rendering SDK. Just create a simple XML file, point
it at your imagery, elevation, and vector data, load it into your favorite
OpenSceneGraph application, and go! osgEarth supports all kinds of data and
comes with lots of examples to help you get up and running quickly and easily.
