Re: [OSGeo-Discuss] Getting a .kmz into GIS
Hi Ezra, looking inside the kmz file, http://www.cstars.miami.edu/media/20100613_Envisat_PM.kmz It appears that the image is actually a PNG file. The kml file references this as a groundOverlay with bounds: for example: 32.4216794699724 23.59737906433506 -84.32169599536186 -90.33200805674051 Using this information it should be possible to view it in most GIS systems, or at least to convert it to a GeoTIFF using GDAL perhaps. Hope this helps!

And also can only be *used* for "research or educational purposes only". Maybe since they have last updated it in 2006 we should give them a poke about freeing it up?

Re: [OSGeo-Discuss] looking for OS softwre to stitch aerial photos automatically
I'm aware of some semi-automatic stitching of areal imagery using Hugin http://hugin.sourceforge.net/ Jeff has used it with video frames from a camera attached to a kite: http://unterbahn.com/2010/01/kite-video-generation-of-aerial-imagery/ And I'm very interested in using Hugin and other Panorama stiching tools to help make cheap aerial imagery as one of the stages within MapWarper.
