Meet Bernie. Bernie Sanders is a Democratic candidate for President of the United States. In 2006, he was elected to the U.S. Senate after 16 years as Vermontâs sole congressman in the House of Representatives. Bernie is now serving his second term in the U.S. Senate after winning re-election in 2012 with 71 percent of the vote.
Satellite imagery at 30-centimeter resolution provides the clearest, most detailed view of the ground from space. See sample imagery to find out for yourself. If you use commercial satellite imagery to map, monitor or assess situations, materials, or infrastructure, you are probably accustomed to 50-centimeter spatial resolution.
If a sensor has a spatial resolution of 20 metres and an image from that sensor is displayed at full resolution, each pixel represents an area of 20m x 20m on the ground. In this case the pixel size and resolution are the same. However, it is possible to display an image with a pixel size different than the resolution. Many posters of satellite images of the Earth have their pixels averaged to represent larger areas, although the original spatial resolution of the sensor that collected the imagery remains the same.
