There's much to discover about this unknown civilization and the treasures they left behind. When a lidar fires its laser at a forest, some of the beam hits the thick canopy, some hits the lower branches, some hits the undergrowth, and finally (if the researcher is lucky) some of it reaches the forest floor. ( Although this was not enough to count as an entire lost city, it was a larger habitation area than had been documented before in the neighbouring regions. BIM, Denver, Colorado is the great way to take your project done. It sends out lasers, records the time it takes them to get back, and creates a map using that information. The longer the pulse width, the more difficult it is to distinguish between separate objects in the same pulse. )Finally, divide the class into seven groups. The earliest use of lidar for archaeological purposes in South and Central America was almost serendipitous. Assign each group one of these words: condition (e.g., like new/damaged/eroded), modification, boundaries, buildings, agriculture, coastlines, and topography. Thankfully, the last two decades have given archaeologists an important new tool: airborne lidar. Many of us are probably familiar with the sprawling Angkor Complex in Cambodia.
