<body class='hmmessage'>Hi Brent and all, I paid a visit to the hypersphere website to download a landsat tile or two and the download keeps being aborted. Is this to be expected? Otherwise I need sources to some background for the ghana, w-africa area. I'm kinda fed up with the nasa wms- i'm trying Brent's possible solution. Thanks.

The providers of the various WMS servers <br>> decide on which Spatial reference systems their data will be served in (usually <br>> one or two). If it is not an SRS you like, with most browser-based WMS clients <br>> you cannot use the data.<br>> <br>> With GeoMoose v2, Dan made an enhancement to warp the imagery from the WMS <br>> server SRS to the SRS you've selected in GeoMoose. A simple warp is not a <br>> rigorous map projection, so the farther you zoom out the worst the warp <br>> approximation is.<br>> <br>> Possible solutions:<br>> 1. Set up your GeoMoose site to use the same SRS as the WMS servers (4326? yuck!)<br>> 2. Pass the WMS stream through Mapserver to re-project it (use Mapserver as a <br>> WMS client, then serve it up to GeoMoose).<br>> 3. Serve the data yourself: Dowload the Landsat data from <br>> http://hypersphere.telascience.org/onearth/. Then combine the bands for natural <br>> color, fuse the pan band to increase the resolution from 30m to 15m, then do <br>> some color adjusting (yikes!).<br>> <br>> Best Regards,<br>> Brent Fraser<br>> <br>> Moore, Richard J wrote:<br>> > Hello all,<br>> > <br>> > <br>> > <br>> > I want to ask a question about the NASA Global Mosaic and how it doesn’t <br>> > match up with the data at a statewide zoom and and farther out.
