When we describe our aerial imagery as highly accurate and consistently reliable, there\u2019s one driving force behind it: ground control points.<\/p>\n<p><strong>What are ground control points, and why do they matter to accuracy?<\/strong><\/p>\n<p>Ground control points (GCPs) are\u2014and have been\u2014the backbone of geospatial data production for many years. They are the way to tie imagery to actual \u201cground truth.\u201d The best way to explain it is to think of it as a measuring process, where a surveyor places a tripod with advanced equipment over an object on the ground that won\u2019t move, i.e., a manhole cover, or something easily detectable in aerial imagery with contrast, and then measures the location of that point with great accuracy. That point becomes an input and a check point when processing imagery to ensure the best final positioning of said imagery. If you want your imagery to be as accurate as possible, the GCPs should be measured to within half of the desired ground sample distance (GSD) of the imagery.<\/p>\n<p>For example, with our 7.5cm ortho, we use GCPs measured to within 3.75cm or better, allowing us to nail it down to an individual pixel in our imagery.<\/p>\n<\/div><\/section><\/div>\n<div class='flex_column av-sz7yxf-1355e78b39a2c8a24a61e323c1ad4499 av_two_fifth  avia-builder-el-8  el_after_av_three_fifth  el_before_av_three_fifth  flex_column_div column-top-margin'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-m1qz4zml-3c1143f588c72634d4656a3b682a118a\">\n.avia-image-container.av-m1qz4zml-3c1143f588c72634d4656a3b682a118a img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-m1qz4zml-3c1143f588c72634d4656a3b682a118a .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-m1qz4zml-3c1143f588c72634d4656a3b682a118a av-styling- avia-align-center  avia-builder-el-9  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" class='wp-image-14130 avia-img-lazy-loading-not-14130 avia_image ' src=\"https:\/\/vexceldata.com\/wp-content\/uploads\/2024\/10\/GCP_example.jpg\" alt='GCP' title='Screenshot'  height=\"295\" width=\"216\"  itemprop=\"thumbnailUrl\"  \/><\/div><\/div><\/div><\/div><div class='flex_column av-13y2nbn-22a44ee07747113306fd7ad613e8c152 av_three_fifth  avia-builder-el-10  el_after_av_two_fifth  el_before_av_two_fifth  first flex_column_div '     ><section  class='av_textblock_section av-m0feeadj-c01b79d47a6c5589ba122f4688012e00'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p><strong>Measuring up to accuracy standards<\/strong><\/p>\n<p>Some imagery companies may only use GPS\/GNSS and IMU data for positional accuracy in their imagery. Without the additional benefit of GCPs, the best absolute accuracy you can achieve is typically around 40-50 cm (GSD). At Vexcel, we combine both GCPs along with GPS\/GNSS and IMU data in the final bundle block adjustment in a modern, high-quality Aerial Triangulation process so that accuracy results can be less than the size of one pixel of the imagery ground sample distance.<\/p>\n<p>And why does it matter to accuracy?

itemprop=\"text\" ><p><strong>Accuracy alignment across Vexcel product lines and incorporation of customer data<\/strong><\/p>\n<p>One of the most significant advantages of having imagery with good absolute accuracy is incorporating non-Vexcel data with <a href=\"https:\/\/vexceldata.com\/au\/products\/\">Vexcel products<\/a>. Customers can use our imagery as a reference for all their other datasets. When a customer overlays their existing data with Vexcel data, the common reference between them is true ground location. The chance of them experiencing minimal errors and getting more accurate results is made more achievable thanks to the pixel-to-data match across our product line.<\/p>\n<p>&#8220;Since all of our data products are derived from the aerial imagery, we have very small errors in between the products,&#8221; says Magnus Olson, Chief Data Officer at Vexcel. &#8220;This is very helpful in eliminating false positive detections when running AI or ML algorithms on our data, and it helps our customers achieve better results.&#8221;<\/p>\n<p>Consider consistency and accuracy across product lines through this urban planning use case: Someone wants to dig a trench and must be careful not to hit a gas line or some other underground object. Unless you know how accurate your map data is, you can very easily dig in the wrong place, thereby creating and causing significant problems, not to mention project delays or costly rework. Combining your data with Vexcel&#8217;s highly accurate imagery can make you more confident in where you dig and why.<\/p>\n<\/div><\/section><\/div>\n<div class='flex_column av-k9xoer-c6d307c8f31fce47ce331a37546507da av_two_fifth  avia-builder-el-23  el_after_av_three_fifth  el_before_av_hr  flex_column_div column-top-margin'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-2439hwz-28f221f622daf7e53b9a15045aa59e36\">\n.avia-image-container.av-2439hwz-28f221f622daf7e53b9a15045aa59e36 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-2439hwz-28f221f622daf7e53b9a15045aa59e36 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-2439hwz-28f221f622daf7e53b9a15045aa59e36 av-styling- avia-align-center  avia-builder-el-24  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" class='wp-image-14135 avia-img-lazy-loading-not-14135 avia_image ' src=\"https:\/\/vexceldata.com\/wp-content\/uploads\/2024\/10\/Pixel-to-data-stack-1030x982-1.jpg\" alt='Vexcel Product Lines' title='Pixel-to-data-stack-1030x982'  height=\"982\" width=\"1030\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/vexceldata.com\/wp-content\/uploads\/2024\/10\/Pixel-to-data-stack-1030x982-1.jpg 1030w, https:\/\/vexceldata.com\/wp-content\/uploads\/2024\/10\/Pixel-to-data-stack-1030x982-1-300x286.jpg 300w, https:\/\/vexceldata.com\/wp-content\/uploads\/2024\/10\/Pixel-to-data-stack-1030x982-1-768x732.jpg 768w, https:\/\/vexceldata.com\/wp-content\/uploads\/2024\/10\/Pixel-to-data-stack-1030x982-1-705x672.jpg 705w\" sizes=\"(max-width: 1030px) 100vw, 1030px\" \/><\/div><\/div><\/div><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-m1s0xry6-7b56ae16fa1c2ddedca804f938117dbf\">\n#top .hr.hr-invisible.av-m1s0xry6-7b56ae16fa1c2ddedca804f938117dbf{\nheight:50px;\n}\n<\/style>\n<div  class='hr av-m1s0xry6-7b56ae16fa1c2ddedca804f938117dbf hr-invisible  avia-builder-el-25  el_after_av_two_fifth  el_before_av_textblock '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div><\/p>\n<section  class='av_textblock_section av-m1qx7tim-c592b1720f726dc04c3b58153ca995b6'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><h5 style=\"text-align: center;\">At the end of the day, accuracy DOES matter<\/h5>\n<p style=\"text-align: center;\">When using aerial imagery, you can gain greater peace of mind by knowing the imagery you\u2019re working from has been matched against GCPs.
