![]() will have the metadata and links to the data as it exists in those many other locations. ![]() It is common for the actual data to be held on other NASA archive sites. The majority of dataset pages on only hold metadata for each dataset. Tens of thousands of datasets are available for you. Landsat 7 images are all taken after 1999 (except for Geocover 1990). is NASA's clearinghouse site for open-data provided to the public.Some USGS aerial images were taken in the early 1990s.Zoomit!: Spot5 10m (colour near full coverage), Robben Island 0.5 m, Johannesburg 2.5 m.Zoomit! (from GSWA): 250K surface geology mosaic, 250K topographic data, Magnetic Intensity, Bouger Gravity.Zoomit! (from LINZ data): 2.5 m (colour and grayscale).USGS Digital Ortho: 1 m (grayscale near full coverage).15 m (Landsat imagery except for polar areas).FIRST (Faint Images of the Radio Sky at Twenty-cm ) Footprint.Magellan Imaging Radar (Color/Greyscale).MDIM (Viking - Mars Digital Image Model).THEMIS (Mars Odyssey - Thermal Emission Imaging System).MOLA (MGS - Mars Orbiter Laser Altimeter hypsometric map).MOC (Mars Global Surveyor - Mars Orbiter Camera).Clementine (40xx - Colour, 30xx - Greyscale).SRTM (SRTM30Plus /SRTMv2/USGS NED) terrain data (includes bathymetry).US imagery (montaged color aerial photography of many major US metropolitan areas).South Africa (colour satellite and aerial imagery).GSWA (Topographic and geological maps of Western Australia).LINZ (montaged color aerial photography of New Zealand).Zoomit! imagery (community produced layer).Urban Area Ortho (montaged color aerial photography of many major US metropolitan areas).Digital Ortho (DOQ - scanned black and white aerial images ).Geocover 1990 & 2000 (pseudo 1990 layer was produced from Landsat 4 & 5 images).The size of all currently available data sets is about 4.6 terabytes. Low resolution Blue Marble datasets are included with the initial download as a user zooms in to certain areas, additional high resolution data is downloaded from the NASA servers. SERVIR-VIZ is a customized version of World Wind developed by IAGT for the SERVIR project.Dapple is aimed at geoscience professionals, and has features aimed at them, such as easy addition WMS servers and a simpler UI very similar to Google Earth's. Dapple is a fork of the NASA World Wind project, it is an Open Source project created by developers at Geosoft. ![]() Currently, Punt is only available for Windows, but long term goals include a desire to move to a cross-platform solution. Punt was based on the code in World Wind 1.3.2, but its initial release has features not found in World Wind 1.3.2 or 1.3.3 (such as support for multiple languages). ![]()
