title=\"formato LAS\">formato LAS<\/a> <\/em><\/strong>(LASer) es un formato de archivo dise\u00f1ado para el intercambio y archivo de datos de nubes de puntos lidar. Es un formato binario abierto especificado por la American Society for Photogrammetry and Remote Sensing (ASPRS). El formato se utiliza ampliamente y se considera un est\u00e1ndar de la industria para datos lidar.<\/p>\n\n\n\n<p>Un <strong><em>archivo LAZ<\/em><\/strong> es un archivo .LAS comprimido. Se ha comprimido para que pueda almacenarse y compartirse con otros m\u00e1s f\u00e1cilmente. Los archivos LAZ suelen tener menos del 20% del tama\u00f1o del archivo LAS a partir del cual se crearon.<\/p>\n\n\n\n<p><strong><em>Archivos Copc<\/em><\/strong>: Los datos de nubes de puntos en formatos de uso com\u00fan como LAS son conjuntos bastante simples de puntos que no est\u00e1n asociados a ninguna estructura de datos de indexaci\u00f3n, y el orden de los puntos puede ser arbitrario. Por consiguiente, es necesario crear una estructura de datos de indexaci\u00f3n cuando se abren estos archivos para poder renderizarlos. Como parte del proceso de indexaci\u00f3n, es necesario reorganizar los puntos para poder acceder a ellos r\u00e1pidamente durante la renderizaci\u00f3n. Una vez finalizada la indexaci\u00f3n, tenemos una estructura de datos en forma de \u00e1rbol en la que cada nodo contiene un subconjunto de la nube de puntos.<\/p>\n\n\n\n<p>Los \u00edndices copc corresponden a <strong><em><a href=\"https:\/\/fr.wikipedia.org\/wiki\/Octree\" title=\"octrees\">octrees<\/a><\/em><\/strong>: \u00e1rboles con ocho nodos hijos sistem\u00e1ticos.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/600px-Octree2.svg.png?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"344\" data-attachment-id=\"11251\" data-permalink=\"https:\/\/www.sigterritoires.fr\/index.php\/chargement-des-donnees-lidar-hd-ign-dans-qgis\/600px-octree2-svg\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/600px-Octree2.svg.png?fit=600%2C344&amp;ssl=1\" data-orig-size=\"600,344\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"600px-Octree2.svg\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/600px-Octree2.svg.png?fit=600%2C344&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/600px-Octree2.svg.png?resize=600%2C344&#038;ssl=1\" alt=\"cubo octree\" class=\"wp-image-11251\" srcset=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/600px-Octree2.svg.png?w=600&amp;ssl=1 600w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/600px-Octree2.svg.png?resize=300%2C172&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/600px-Octree2.svg.png?resize=150%2C86&amp;ssl=1 150w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/07\/600px-Octree2.svg.png?resize=250%2C143&amp;ssl=1 250w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/a><\/figure>\n\n\n\n<p>Este tipo de \u00e1rbol se corresponde bien con los objetos 3D: cuando tenemos un cubo, que representa nuestro universo 3D, determinamos un punto central a partir del cual podemos dividir nuestro cubo en 8 cubos, pudiendo cada uno de estos cubos dividirse en 8 cubos y as\u00ed sucesivamente.<br>Esto es un octree y es el formato de archivo indexado que utiliza QGis para los archivos LIDAR.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Carga de nubes de puntos en QGis<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Carga de datos clasificados<\/h3>\n\n\n\n<p>Este es el caso m\u00e1s sencillo.
