The USGS leads the interagency 3D Elevation Program (3DEP), which has the goal to complete acquisition of nationwide lidar (IfSAR in AK) to provide the first-ever national baseline of consistent high-resolution elevation data both bare earth and 3D point clouds collected in a timeframe of less than a decade. Lidar captures a digital census of forest volume and forest type.. Archaeologists at Miami University and the Yucatan have carried out the first lidar study of the 80 mile stone highway (sacbe) that connected the Maya sites of Coba and Yaxuna in the Yucatan. In other parts of the world similar agrarian cities with low population densities had already been found. Archaeological predictions for the new year include: discoveries from Egypt's "lost golden city," new finds from Qumran and evidence that may shed light on what life was like 11,000 years ago. The same year Canuto and his colleagues were learning the true depths of Maya development in Guatemala, archaeologist Takeshi Inomata from the University of Arizona was investigating a site in Mexico using lidar data freely available online. With careful data processing, the users could strip away the first returns from the canopy so that only the ones from the ground remained, giving them a view of the bare earth below. The fortress has a diameter of 144 meters, with 4 main gates and paved wooden roads. These data serve many purposes, including ensuring that geological and geophysical surveys are accurate.
