2000.09.29 02:31 "OpenEV 0.9.0 Release", by Frank Warmerdam


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:

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.
