Contest category: Unique Geomorphologic Images Application areas: Cartography, Land Information/Land Use, Internet/Web Mapping/Web Services Description: This image of the state of California, USA was created by mosaicking 33 Landsat 7 ETM satellite scenes captured in the year 1999-2001 time frame. It shows the wide range of geographic diversity in the state, from the forested mountains to the fertile central valley agriculture to the southwestern desert to the sprawling urban areas. The state has over 1600 miles (2570Km) of coastline along the Pacific Ocean. This image helps state-wide analysis and mapping of land use and land cover at up to 1:50,000 scale detail for a variety of geographic applications. Landsat bands 3, 2 and 1 were merged with the Panchromatic band to create "natural color" image at 15-meter resolution for the entire state. Geographic location: State of California, USA Image resolution: 15 meters Source of imagery: NASA’s orthorectified Landsat 7 public domain imagery from the University of Maryland’s GLCF website Commercial image processing software used: ER Mapper 6.3 Image processing technique employed: Virtual mosaics of bands 3,2,1 and the Pan band were merged using a modified RGB Intensity technique — Eric Augenstein (eric@es-geo.com), Earthstar Geographics, USA |
