Free data visualization components software for mac

Xiph QuickTime Components 0.1.9 is a perfect way for Mac users who want to use Xiph formats in any QuickTime-based application, e.g. playing Ogg Vorbis in iTunes or producing Ogg Theora with iMovie. Xiph QuickTime Components (XiphQT) is a set of QuickTime and Macintosh OS X plug-ins.

Major Features:

1. Provides support for Xiph media compression and container formats.
2. If you are an end user: installing XiphQT components is all you need to start using Xiph-formatted media files in a variety of applications - for example, listening to Ogg/Vorbis files in QuickTime Player or iTunes. The programming interfaces used in XiphQT allow the provided functionality to be available transparently to all media handling applications using QuickTime or OS X component mechanisms.
3. If you are a programmer, you have built a Macintosh Core Audio or QuickTime-based application and would like to add Xiph formats support: most of the time there is hardly anything you will need to do to add support.

Enhancements:

• Reduced memory usage
• Fixed playback of HD content
• Fixed leaking memory when handling files containing Theora streams (#1379)
• Added code to make Ogg exporter work with iMovie '08
• Added code to properly handle bigger packets in Theora decoder allowing XiphQT to handle HD content without visual artifacts.

Requirements:

• Version 10.3.9 or 10.4 and later
• QuickTime for Mac OS X - version 7 or later

GRASS GIS 6.4rc5 is stand for Geographic Resources Analysis Support System, which used for data management, image processing, graphics production, spatial modelling, and visualization of many types of data. It is Free (Libre) Software/Open Source released under GNU General Public License (GPL). GRASS is official project of the Open Source Geospatial Foundation.
Originally developed by the U.S. Army Construction Engineering Research Laboratories (USA-CERL, 1982-1995), a branch of the US Army Corp of Engineers, as a tool for land management and environmental planning by the military, GRASS has evolved into a powerful utility with a wide range of applications in many different areas of scientific research. GRASS is currently used in academic and commercial settings around the world, as well as many governmental agencies including NASA, NOAA, USDA, DLR, CSIRO, the National Park Service, the U.S. Census Bureau, USGS, and many environmental consulting companies.
The new GRASS 6 release introduces a new topological 2D/3D vector engine and support for vector network analysis. Attributes are now managed in a SQL-based DBMS. A new display manager has been implemented. The NVIZ visualization tool was enhanced to display 3D vector data and voxel volumes. Messages are partially translated (i18N) with support for FreeType fonts, including multibyte Asian characters. New LOCATIONs can be auto-generated by EPSG code number. GRASS is integrated with GDAL/OGR libraries to support an extensive range of raster and vector formats, including OGC-conformal Simple Features.
The GRASS Development Team has grown into a multi-national team consisting of developers at numerous locations.
In September 2006, the GRASS Project Steering Commitee was formed which is responsible for the overall management of the project. The PSC is especially responsible for granting SVN write access.
Major Features:

1. GRASS (Geographic Resources Analysis Support System) is a raster/vector GIS, image processing system, and graphics production system.
2. GRASS contains over 350 programs and tools to render maps and images on monitor and paper; manipulate raster, vector, and sites data; process multi spectral image data; and create, manage, and store spatial data.
3. GRASS uses both an intuitive windows interface as well as command line syntax for ease of operations.
4. GRASS can interface with commercial printers, plotters, digitizers, and databases to develop new data as well as manage existing data.
   
5. GRASS supports workgroups through its LOCATION/MAPSET concept which can be set up to share data over NFS (Network File System). Keeping LOCATIONs with their underlying MAPSETs on a central server, a team can simultaneously work in the same project database.
   
6. GRASS is released under GNU GPL, the source code (5.x: more than 1 million lines of C; 6.x 500k SLOC) is completely available.
7. GRASS provides a sophisticated GIS library which can be used for own developments.
