In 2023 they completed the first complete coverage of England at 1m resolution, providing an incredible resource for understanding the historic environment.

The most common raster images differ based on the point at which the pulses are returned to the sensor and the resulting data is processed. The Digital Surface Model (DSM) is the first return or highest point of pulse return, usually showing the whole landscape, including the ground surface in open areas, vegetation, woodland canopy and buildings. The Digital Terrain Model (DTM) is created by filtering the LiDAR dataset to remove all non-ground returns such as those that reflected from vegetation and buildings. This filtering allows features under the vegetation canopy to be visualised.<\/p>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-spacer stk-block-spacer stk--no-padding stk-block stk-92d92cd\" data-block-id=\"92d92cd\"><style>.stk-92d92cd {height:80px !important;}@media screen and (max-width: 1023px){.stk-92d92cd {height:80px !important;}}<\/style><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns stk-block-columns stk-block stk-c33a659\" data-block-id=\"c33a659\"><style>.stk-c33a659 {max-width:1000px !important;min-width:auto !important;}<\/style><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-c33a659-column\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-bbca50d\" data-v=\"4\" data-block-id=\"bbca50d\"><style>@media screen and (min-width: 768px){.stk-bbca50d {flex:var(--stk-flex-grow, 1) 1 33.3% !important;}}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-bbca50d-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-bbca50d-inner-blocks\">\n<div class=\"wp-block-stackable-image stk-block-image stk-block stk-d08a855\" data-block-id=\"d08a855\"><figure><span class=\"stk-img-wrapper stk-image--shape-stretch\"><img loading=\"lazy\" decoding=\"async\" class=\"stk-img wp-image-2043\" src=\"https:\/\/www.kentlidar.org.uk\/ridgeway\/wp-content\/uploads\/2024\/11\/Screenshot-2024-11-27-092149.png\" width=\"916\" height=\"707\" alt=\"Aircraft scanning the ground using LiDAR\" srcset=\"https:\/\/www.kentlidar.org.uk\/ridgeway\/wp-content\/uploads\/2024\/11\/Screenshot-2024-11-27-092149.png 916w, https:\/\/www.kentlidar.org.uk\/ridgeway\/wp-content\/uploads\/2024\/11\/Screenshot-2024-11-27-092149-300x232.png 300w, https:\/\/www.kentlidar.org.uk\/ridgeway\/wp-content\/uploads\/2024\/11\/Screenshot-2024-11-27-092149-768x593.png 768w\" sizes=\"auto, (max-width: 916px) 100vw, 916px\" \/><\/span><\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-f599ea7\" data-v=\"4\" data-block-id=\"f599ea7\"><style>.stk-f599ea7-inner-blocks{justify-content:center !important;}@media screen and (min-width: 768px){.stk-f599ea7 {flex:var(--stk-flex-grow, 1) 1 66.7% !important;}}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-f599ea7-container stk--no-background stk--no-padding\"><div class=\"stk--column-flex stk-block-content stk-inner-blocks stk-f599ea7-inner-blocks\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-9fe81b8\" id=\"find-out-more\" data-block-id=\"9fe81b8\"><h2 class=\"stk-block-heading__text\">Find out more!<\/h2><\/div>\n\n\n\n<p>To find out more about how LiDAR can be used to understand the landscape and identify archaeological features join the Ridgeway portal volunteers to take our online training course.<\/p>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-spacer stk-block-spacer stk--no-padding stk-block stk-a7023ef\" data-block-id=\"a7023ef\"><style>.stk-a7023ef {height:130px !important;}@media screen and (max-width: 1023px){.stk-a7023ef {height:80px !important;}}<\/style><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns alignfull stk-block-columns stk-block stk-51483c5 stk-block-background stk--has-background-overlay\" data-block-id=\"51483c5\"><style>.stk-51483c5 .stk--block-align-51483c5{align-items:center !important;}.stk-51483c5 {background-color:#000000 !important;background-image:url(https:\/\/www.kentlidar.org.uk\/ridgeway\/wp-content\/uploads\/2024\/11\/the-ridgeway-national-trail-map.jpg) !important;padding-top:150px !important;padding-bottom:150px !important;margin-bottom:0px !important;}.stk-51483c5:before{background-color:#000000 !important;opacity:0.6 !important;}.stk-51483c5-column{--stk-column-gap:35px !important;}@media screen and (max-width: 1023px){.stk-51483c5 {padding-top:100px !important;padding-bottom:100px !important;}}<\/style><div class=\"stk-row stk-inner-blocks stk--block-align-51483c5 stk-block-content stk-content-align stk-51483c5-column\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-6cfc4a8\" data-v=\"4\" data-block-id=\"6cfc4a8\"><style>.stk-6cfc4a8-container{margin-top:0px !important;margin-right:0px !important;margin-bottom:0px !important;margin-left:0px !important;}@media screen and (min-width: 768px) and (max-width: 1023px){.stk-6cfc4a8 {flex:var(--stk-flex-grow, 1) 1 calc(100% -

The wealth of information in the LiDAR models needs to be captured and interpreted to be of real use to anyone wanting to understand the landscape, and this is where our amazing volunteer citizen scientists step in. The information gathered for this project will allow us to better manage and protect this special historic landscape for future generations to enjoy and explore.<\/span><\/strong><\/p><\/div>\n<\/div><\/div><\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>LiDAR technology LiDAR (Light Detection and Ranging) is based on the principle of measuring distance through the speed and intensity recorded for a pulse of light to be fired from sensor equipment and reaching a target, before sending a return signal.
