Aerial Survey

One of the most common, versatile, and economical forms of remote sensing is aerial photography. Historically most aerial photography has been film based. In recent years, however, digital photography has become increasingly widely used. Aerial photography gives a bird’s eye view of large areas, enabling us to see earth surface features in their spatial location. CSW now will use the UAV aerial photos technique. In this technique CSW can get a resolution of 1cm with 100m flying height, and can build also the DTM directly with very accurate results.
