Folks, 

I am pleased to announce release 0.9.0 of OpenEV.  While OpenEV does a number
of things, I hope it will be of interest to this audience as a high 
performance viewer of various raster formats including TIFF/GeoTIFF.  It is
OpenGL based (so it is only really high performance on OpenGL accelerated
systems), and available for Windows 98/NT/2000, Linux, and assorted unix
platforms.  

While it can display directly from a variety of formats, the "native" format
is GeoTIFF.  The raster import function translates the ingested image into
a tiled GeoTIFF file with overviews, optimized for raster display, even for
very large images.

It is built on GDAL (Geospatial Data Abstraction Library), and includes what
I hope is sophisticated support for TIFF variations.  It includes support 
for 16bit, floating point, and complex sample types in the TIFF file (note
complex sample types are a GDAL extension to TIFF discussed on these lists
a few months ago).  

OpenEV is Open Source, and may be a suitable platform for a variety of imaging
applications.  Especially geospatial or scientific applications.  In addition
to OpenGL and GDAL, it also incorporates Gtk+, Python, Numerical Python, 
and PROJ.4 technologies.  It is already being used as a basis for three
commercial projects.

Pre-built binaries are available for Windows, Linux, Solaris and Irix.  More
information, binaries, and source can be found at:

  http://openev.sourceforge.net/

For those using large TIFF files for non-geospatial applications, I think
OpenEV may be of interest because of it's high performance with large files.
For those pursuing geospatial applications, I think OpenEV might also be
of interest for it's relative sophistication with projections, and support
of other significant geospatial formats.  

I and the other OpenEV developers are interested in feedback, and would
welcome cooperation with developers interested in extending or utilizing
OpenEV.  Please feel free to email me directly if you have questions.

Best regards,
