[OSGeo-Discuss] Getting a .kmz into GIS
Hi Everyone, I need help in importing or converting a .kmz file so that I can view it in my GIS. I work for a small environmental NGO in coastal Louisiana, and we are currently assisting emergency responders tackling BP's oil spill. One of my tasks is surveillance of oil streamers and globules as they approach the coast. To help with this, I am using radar satellite imagery obtained from CSTARS (https://www.cstars.miami.edu/.) The website provides downloadable .kmz files. When I open these files in an GeoBrowser, I can view a georeferenced .tif image. However, I have not figured out how to get geotiff into my GIS, where I can overlay winds, currents, tides, and waves to project likely movement of observed oil globules. I have tried exporting the image in Google Earth, Nasa Worldwind and ArcGIS Explorer. I have also tried opening the .kmz in a half dozen or so GIS viewers. I have also tried converting the file using GDAL. I have also tried changed the file extension .zip and then uncompressing it. None of these attempts have worked. Please let me know if you how to extract the .tif file embedded in the .kmz. Thanks, Ezra ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

I think such command line tools exist on windows too. You don't have to rename it before extracting. Good luck !

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: north32.4216794699724/north south23.59737906433506/south east-84.32169599536186/east west-90.33200805674051/west 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! Tim On 14 June 2010 14:16, Ezra Boyd ebo...@tigers.lsu.edu wrote: Hi Everyone, I need help in importing or converting a .kmz file so that I can view it in my GIS.

Re: [OSGeo-Discuss] Getting a .kmz into GIS
Looks to me like the PNGs referenced in the KML are 2 logos and a small image preview icon. The actual image file seems to be called 20100614151937_Envisat_VV.tif, but I can't figure out the full web URL. --- Raj On Jun 14, at 9:29 AM, Tim Waters wrote: 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.

(At least, not one that the KML uses.) the name tag is just a descriptive element; the actual 'icon' (image) is the small_scaled.png file included in the KMZ file, Tim was right. -- Chris north32.4216794699724/north south23.59737906433506/south east-84.32169599536186/east west-90.33200805674051/west 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.
