You can digitally remove surface features to reveal long-forgotten archaeology sites. This helps us to better understand and conserve the historic landscape.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In March 2023, high resolution Lidar was acquired for 345 km2 of the northern section of the National Park area. This landscape has a rich history of human activity spanning back thousands of years. Lidar can help reveal and trace this story.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A lidar sensor uses a laser to measure the distance between the aircraft and the ground. By recording millions of these measurements we can create a record of the relative heights of the ground surface. The laser also reflects off trees and buildings, cars, cows and cairns \u2013 anything present in the landscape at the time of the survey is recorded. This means that the models must be interpreted by humans to make sense of the information they contain.<\/p>\n\n\n\n<div class=\"wp-block-columns\">\n<div class=\"wp-block-column\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"159\" src=\"https:\/\/i0.wp.com\/www.lidar.cymru\/arfordirpenfro\/wp-content\/uploads\/2025\/01\/pulse.gif?resize=150%2C159&#038;ssl=1\" alt=\"\" class=\"wp-image-930\" style=\"width:215px;height:auto\" data-recalc-dims=\"1\"\/><\/figure>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-column\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"980\" height=\"770\" src=\"https:\/\/i0.wp.com\/www.lidar.cymru\/arfordirpenfro\/wp-content\/uploads\/2025\/01\/DSM_RB.jpg?resize=980%2C770&#038;ssl=1\" alt=\"\" class=\"wp-image-931\" srcset=\"https:\/\/i0.wp.com\/www.lidar.cymru\/arfordirpenfro\/wp-content\/uploads\/2025\/01\/DSM_RB.jpg?w=980&amp;ssl=1 980w, https:\/\/i0.wp.com\/www.lidar.cymru\/arfordirpenfro\/wp-content\/uploads\/2025\/01\/DSM_RB.jpg?resize=744%2C585&amp;ssl=1 744w\" sizes=\"auto, (max-width: 980px) 100vw, 980px\" data-recalc-dims=\"1\" \/><figcaption class=\"wp-element-caption\">DSM showing Vegetation and Buildings<\/figcaption><\/figure>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-column\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"985\" height=\"766\" src=\"https:\/\/i0.wp.com\/www.lidar.cymru\/arfordirpenfro\/wp-content\/uploads\/2025\/01\/DTM_RB.jpg?resize=985%2C766&#038;ssl=1\" alt=\"\" class=\"wp-image-932\" srcset=\"https:\/\/i0.wp.com\/www.lidar.cymru\/arfordirpenfro\/wp-content\/uploads\/2025\/01\/DTM_RB.jpg?w=985&amp;ssl=1 985w, https:\/\/i0.wp.com\/www.lidar.cymru\/arfordirpenfro\/wp-content\/uploads\/2025\/01\/DTM_RB.jpg?resize=744%2C579&amp;ssl=1 744w\" sizes=\"auto, (max-width: 985px) 100vw, 985px\" data-recalc-dims=\"1\" \/><figcaption class=\"wp-element-caption\">DTM with Vegetation and Buildings removed<\/figcaption><\/figure>\n<\/div><\/div>\n<\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Find out more!<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">To find out more about how lidar can be used to understand the landscape and identify archaeological features join the Arfordir Penfro portal volunteers to take our online training course.<\/p>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group alignfull why-important-bg is-style-no-margin-vertical has-color-accent-text-mod-color has-text-color\" style=\"padding-top:130px;padding-right:10px;padding-bottom:130px;padding-left:10px\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-container-core-group-is-layout-c90bb70c wp-block-group-is-layout-constrained\"><div class=\"alignwide-wrap\" data-block=\"columns\">\n<div class=\"wp-block-columns alignwide\">\n<div class=\"wp-block-column\">\n<h2 class=\"wp-block-heading has-display-1-font-size\" style=\"font-style:normal;font-weight:400\">Why is it<br>important?<\/h2>\n<\/div>\n\n\n\n<div class=\"wp-block-column\">\n<p class=\"wp-block-paragraph\">Rapidly increasing vegetation cover is obscuring recorded and unrecorded sites.
