Blue Marble Geotiff Maps

In the maps shown here, dark brown pixels show high aerosol concentrations, while tan pixels show lower concentrations, and light yellow areas show little or no aerosols. Global Mapper is the low-cost and easy GIS software supporting more than 250 file formats.

NASA's Blue Marble: Next Generation images show Earth in true color. The images show how the surface would look to a human in space if our world had no clouds and no atmosphere. NASA's Terra satellite collected these images. There is one Blue Marble image for each month of the year 2004. These images allow us to explore changes on Earth's lands over time. Notice how the patterns of green (trees and plants), brown (exposed land surface), and white (snow) change from winter through spring, summer, and fall.

This spectacular “blue marble” image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet. These images are freely available to educators, scientists, museums, and the public. This record includes preview images and links to full resolution versions up to 21,600 pixels across. Much of the information contained in this image came from a single remote-sensing device-NASA’s or MODIS. Australian Shepherd Breeders.

Flying over 700 km above the Earth onboard the satellite, MODIS provides an integrated tool for observing a variety of terrestrial, oceanic, and atmospheric features of the Earth. The land and coastal ocean portions of these images are based on surface observations collected from June through September 2001 and combined, or composited, every eight days to compensate for clouds that might block the sensor’s view of the surface on any single day. Two different types of ocean data were used in these images: shallow water true color data, and global ocean color (or chlorophyll) data. Topographic shading is based on the GTOPO 30 elevation dataset compiled by the U.S.

Geological Survey’s EROS Data Center. MODIS observations of polar sea ice were combined with observations of Antarctica made by the National Oceanic and Atmospheric Administration’s AVHRR sensor—the Advanced Very High Resolution Radiometer. Game Renamer.exe.

The cloud image is a composite of two days of imagery collected in visible light wavelengths and a third day of thermal infra-red imagery over the poles. Make Faces Google Sketchup Plugin.
