Radar Open Source Community Software
The Confused Life blog made me aware of the RAT project, open source radar tools for synthetic aperture radar (SAR) data processing. From the project's website: "Our motivation to start the development of RAT is that modern remote sensing software like Erdas Image or ENVI include only some basic SAR functionality. Advanced algorithms in SAR polarimetry (PolSAR), interferometry (InSAR) and polarimetric interferometry (PolInSAR) have to be implemented by oneself. So we descided to start the development of RAT. RAT should bring modern SAR algorithms to a wider user-base by simplifying in particular the data handling and processing of complex SAR data." See also related stories below.

ENVI 4.2 Released and Documentation Online [+]
Yesterday's RSI newsletter announced the last month release of ENVI 4.2. It includes a new suite of vegetation analysis tools, geospatial statistics tool, log residuals tool and autoregistration tool. RSI also indicates that ENVI's documentation can now be found online, and so are the tutorials.
ESA RADAR Processing Tutorials and Free Software [+]
All Things Geography points to new ESA RADAR polarimetry tutorials. From the introduction: "[...] a wide-ranging tutorial, which aims to provide a grounding in polarimetry and polarimetric interferometry with a view to stimulating research and development of scientific applications that exploit polarimetric data and techniques."
ERDAS Imagine 9.1 Released [+]
Leica Geosystems Geospatial Imaging released ERDAS Imagine 9.1. From the press release: "GIS users now have more flexibility and choices with expanded platform support such as Windows XP Professional Edition 64-bit and Sun Solaris 10. The IMAGINE NITF module has been significantly enhanced addressing many key requirements for the Defense community. Leica Geosystems is also the first commercial software company to provide support for the Indian Cartosat topographic mapping satellite demonstrating enhanced capabilities for Cartosat orthorectification."
Optiks: New Open Source Satellite Imagery Processing Software [+]
The OSGeo-Discuss mailing list informs us of a new open source satellite imagery processing software named Optiks. The official website. From the article: "Opticks is used by scientists and analysts within the Department of Defense Intelligence Community to analyze remote sensing data and produce actionable intelligence. Opticks supports Imagery, Motion Imagery, Synthetic Aperture Radar (SAR), and multispectral and hyperspectral remote sensing data." From the OSGeo post: "A couple of observations: 1. The Contributors Agreement (click on the Contributors Agreement link on the left side of the page) is likely rather intimidating for the average open source contributor. 2. It doesn't use GDAL (although it does have OSSIM as a dependency)." This reminds me of the RATS software, recently discussed, and GRASS GIS comes to mind (though GRASS doesn't do hyperspectral?).
New TerraSAR-X Image and Video Gallery [+]
The EOPortal introduces the new image and video gallery for the German TerraSAR-X satellite. TerraSAR-X was launched last summer. From the site: "TerraSAR-X will fly around Earth for five years at an altitude of about 514 kilometres, scanning the surface of our planet with radar without regard to weather, cloud and daylight conditions. The satellite has several image settings at its disposal which, resembling the action of a zoom lens, either afford a view of a relatively large area (the so-called ScanSAR mode) or show many details in smaller segments called SpotLight images. The StripMap mode represents a compromise between wider coverage and higher definition." See also some related stories below.
ERDAS Imagine 9.2 and RedSpider Enterprise 3.5.2 Released [+]
Leica Geosystems Geospatial Imaging announced the release of ERDAS Imagine 9.2 and of RedSpider Enterprise 3.5.2. From the press releases: "With an improved surfacing tool, ERDAS IMAGINE 9.2 increases its handling from 500,000 points to more than 50 million points, quickly and efficiently. Promoting classification and productivity, ERDAS IMAGINE 9.2 now includes IMAGINE Subpixel Classification and swift and accurate image segmentation tools in IMAGINE Professional. Additionally, ERDAS IMAGINE now provides ECW support, offering increased interoperability with the recently acquired ER Mapper suite of products." And for RedSpider: "RedSpider Enterprise 3.5.2 empowers users to build customized geospatial web applications." See also related stories below.

  • Based on IDL?

    Unfortunately it looks like it is based on proprietary software - IDL. Unless I'm missing something.
