These light pulses\u2014combined with other data recorded by the airborne system \u2014 generate precise, three-dimensional information about the shape of the Earth and its surface characteristics.<\/p>\n\n\n\n<p>A lidar instrument principally consists of a laser, a scanner, and a specialized&nbsp;<a href=\"https:\/\/oceanservice.noaa.gov\/geodesy\/gps\/\">GPS<\/a>&nbsp;receiver. Airplanes and helicopters are the most commonly used platforms for acquiring lidar data over broad areas. Two types of lidar are&nbsp;<a href=\"https:\/\/oceanservice.noaa.gov\/facts\/bathymetry.html\">topographic and bathymetric<\/a>. Topographic lidar typically uses a near-infrared laser to map the land, while bathymetric lidar uses water-penetrating green light to also measure seafloor and riverbed elevations.<\/p>\n\n\n\n<p>Let&#8217;s put this into a perspective. Just say you were flying over a canopy of trees which are hundreds of years old, and underneath these trees are the Inca temples and cities all now lost to the thick jungles. BUT lidar can and has already unravelled many of these secrets.<\/p>\n\n\n\n<p>Now to introduce you to somewhere closer to home, and the entirety of Essex. Enjoy.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Light Detection and Ranging, in Essex<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4,3],"tags":[],"class_list":["post-1","post","type-post","status-publish","format-standard","hentry","category-lidar","category-lidar-and-essex"],"_links":{"self":[{"href":"https:\/\/uklidar.com\/index.php?rest_route=\/wp\/v2\/posts\/1","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/uklidar.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/uklidar.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/uklidar.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/uklidar.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1"}],"version-history":[{"count":8,"href":"https:\/\/uklidar.com\/index.php?rest_route=\/wp\/v2\/posts\/1\/revisions"}],"predecessor-version":[{"id":38,"href":"https:\/\/uklidar.com\/index.php?rest_route=\/wp\/v2\/posts\/1\/revisions\/38"}],"wp:attachment":[{"href":"https:\/\/uklidar.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/uklidar.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/uklidar.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
