LIDAR stands for Light Detection and Ranging. This is a narrow laser beam that can be used to map physical features with high resolutions as can be seen by this map of the coast of San Francisco, California. This type of map is perfect for atmospheric research and meteorology because of its accuracy. NOAA has used this image for shoreline mapping as well as the mean high water tide. Experiments are performed with this type of mapping to quantitatively compare it using VDatum to shoreline compiled with traditional photogrammetric techniques. This will provide NOAA with more accurate data.
