Blue Marble Download Geotiff Maps
.UPDATE 8/13/2011. – I have made a couple important updates. First, I have released a global version of the very popular 90-meter terrain map. I have also relaxed the licensing restrictions to allow for commercial use.

See below for more details on both of these changes.There are many ways to visualize the terrain and topography of the Earth’s surface on a map. Recent technological advances allow us to see the Earth’s surface in ways that have never been possible before. The terrain maps presented below were created with a desktop computer by combining over 150 gigabytes of elevation and imagery data from the sources listed below.The resulting terrain maps show an amazing level of detail and allow us to see the surface of the Earth in a way that is not possible by viewing any of the source data sets on their own. In short, the SRTM and GTOPO elevation data was used to add hill shading to the Blue Marble imagery.
The links below will allow you to download maps for various parts of the world. Quick warning, that the maps are very high resolution and some of them are very large downloads.I have also processed several of these with Microsoft SeaDragon. This allows you to view them in their full resolution very easily in a web browser.I’ve also decided to ease my licensing limitation a bit and release the Global Terrain Maps under the. Please credit the Google Earth Library and provide a hyperlink to with any online reuse or distribution of this map.
In addition, you must include a citation of “ASTER GDEM is a product of METI and NASA” somewhere near the Version 2 map. Additional suggested citations and detailed copyright information are included in the readme.txt file that can be found in the folder containing the map tiles. The credit and citations can go in the end-credits for multimedia presentations.The maps currently available are listed below:Global Terrain Maps:. – 580 MB GeoTIFF file at 1,000 meter resolution. – 8 GB GeoTIFF split into 72 tiles at 250 meter resolution.NEW 8/13/2011. – 52 GB GeoTIFF split into 648 tiles at 90 meter resolutionCountry Terrain MapsI have made individual maps for a limited number of countries.

Download Geotiff From Google Earth
I am having the hardest time displaying these in Google Earth Pro. I import the geo-tiffs and Google Earth grinds away for 10 to 20 minutes, then it either doesn’t show anything, or it crashes.
I have a large video card (1 GB VRAM) and 14 GB of RAM, so I don’t think that is the problem. Is there a known problem with Google Earth Pro (for the Mac)–and if so, any known work-arounds?I do not have Google Earth Pro, but I’m not surprised to hear that the GeoTIFF files do not work due to their size. I would suggest using a GIS program to edit out a smaller area from the GeoTIFF and try that. You could also purchase a program called global mapper, which would convert them to SuperOverlays, which can then be viewed in Google Earth.
Natural Earth features 7 types of raster files at 1:10 million-scale to suit your bandwidth and content focus. Two versions of the 10 million-scale raster data are offered: high resolution files at 21,600 x 10,800 pixels and low resolution at 16,200 x 8,100. The raster files register precisely with the 10m vector data. Embedded raster content includes: land cover, shaded relief, ocean water, and drainages with lakes. All files include a TFW world file.Note: Choose a category below to see matching downloads.Files have been downloaded 658,939 times.Shaded relief combined with custom elevation colors based on climate—humid lowlands are green and arid lowlands brown. As in nature, the map colors gradually blend into one another across regions (x and y axis) and from lowlands to highlands (z axis), hence the name cross-blended hypsometric tints.Satellite-derived land cover data and shaded relief presented with a light, natural palette suitable for making thematic and reference maps. Natural Earth I is available with ocean bottom data, or without.This data derived from Natural Earth 1 portrays the world environment in an idealized manner with little human influence.
The softly blended colors of Natural Earth 2 are ideal for historical mapping, because it shows the world much as it looked before the modern era.Blended depth colors and relief shading of the ocean bottom derived from CleanTOPO2 data. The ocean color extends beneath land areas as a flat tint—mask it with the 10m Natural Earth vector shoreline, or a shoreline from another data source.Grayscale shaded relief of land areas only derived from downsampled SRTM Plus elevation data clipped to the 10 million-scale Natural Earth coastline. A flat gray tint fills water areas.Worldwide terrain depicted monochromatically in shades of gray. It combines shaded relief and regionally adjusted hypsography that emphasizes both high mountains and the micro terrain found in lowlands.Generalized shaded relief of land areas only fitted to the 10 million-scale Natural Earth coastline, drainages, political boundaries, and spot elevations. A flat gray tint fills water areas.
Relief coverage also includes southern Canada, Mexico, Central America, and the Caribbean.
