Using their Phase II lidar point clouds, we created a new shaded relief and DEM raster tile sets for web mapping. While most mapping applications focus on ground elevations, we use the above-ground elevations to make a digital surface model (DSM). These elevations show buildings, trees, and even cars.<\/p>\n<p>These above-ground elevations, however, have unique challenges. The latest project attempts to minimize errors and create visually impactful shaded relief and RGB terrain layers from DEMs for elevations.<\/p>\n<p>Check out the preview here: <a href=\"https:\/\/outrageGIS.com\/maps\/new-circle\">outrageGIS.com\/maps\/new-circle<\/a><\/p>\n<\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"750\" src=\"https:\/\/www.outragegis.com\/trails\/wp-content\/uploads\/2025\/03\/index-example-page.jpg-1024x750.png\" alt=\"Screenshot map web page\" class=\"wp-image-19650\" srcset=\"https:\/\/www.outragegis.com\/trails\/wp-content\/uploads\/2025\/03\/index-example-page.jpg-1024x750.png 1024w, https:\/\/www.outragegis.com\/trails\/wp-content\/uploads\/2025\/03\/index-example-page.jpg-300x220.png 300w, https:\/\/www.outragegis.com\/trails\/wp-content\/uploads\/2025\/03\/index-example-page.jpg-150x110.png 150w, https:\/\/www.outragegis.com\/trails\/wp-content\/uploads\/2025\/03\/index-example-page.jpg-768x562.png 768w, https:\/\/www.outragegis.com\/trails\/wp-content\/uploads\/2025\/03\/index-example-page.jpg-1536x1124.png 1536w, https:\/\/www.outragegis.com\/trails\/wp-content\/uploads\/2025\/03\/index-example-page.jpg-2048x1499.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<div class=\"wp-block-jetpack-markdown\"><p><em>Lexington\u2019s UKy campus<\/em><\/p>\n<\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>KyFromAbove has developed elevation datasets for public use, utilizing Phase II lidar point clouds to create shaded relief and DEM raster tile sets for web mapping.
