Laser Mapping The Earth
NASA scientist Bryan Blair introduces a laser mapping sensor known as LVIS (the Land, Vegetation, and Ice Sensor), which is flown by aircraft over target areas to collect data on surface topography and vegetation cover. Bryan also discusses the benefits to mounting LVIS onto high-altitude, long-duration aircraft such as the Global Hawk.
NASA's Land, Vegetation, and Ice Sensor, known as "LVIS," is a scanning laser altimeter instrument that is flown on aircraft.
Now mounted on the high-altitude, long duration Global Hawk UAV, LVIS can help scientists better map the Earth. The data that LVIS provides, combined with high-resolution still images, can be used to create interactive 3-D maps.
