He aqu\u00ed un tutorial de 5 cap\u00edtulos sobre la nueva funci\u00f3n de QGis de la versi\u00f3n 3.26: perfiles de elevaci\u00f3n.<\/p>\n\n\n\n

Cap\u00edtulo 1: Perfiles a partir de capas vectoriales<\/a><\/p>\n\n\n\n

Cap\u00edtulo 2: Perfiles a partir de capas r\u00e1ster<\/a><\/p>\n\n\n\n

Cap\u00edtulo 3: Perfiles a partir de nubes de puntos (Lidar)<\/p>\n\n\n\n

Cap\u00edtulo 4: Perfiles en el dise\u00f1ador de impresi\u00f3n<\/p>\n\n\n\n

Cap\u00edtulo 5: Perfiles en QField<\/a><\/p>\n\n\n\n\n\n\n\n

Cap\u00edtulo 3: <\/h1>\n\n\n\n
En este tercer cap\u00edtulo, veremos dos temas:<\/p>\n\n\n\n
\n
El primero es una opci\u00f3n que existe para las capas vectoriales: la EXTRUSI\u00d3N de caracter\u00edsticas.<\/li>\n\n\n\n
En segundo lugar, veremos c\u00f3mo crear perfiles a partir de nubes de puntos, en particular datos LIDAR.<\/li>\n<\/ul>\n\n\n\n

Esta representaci\u00f3n es coherente con la noci\u00f3n de intersecci\u00f3n entre estos tipos de capas y una l\u00ednea de perfil. Si las entidades son de tipo XYZ, o si se les asigna un valor Z si son de tipo XY, las representaciones de las entidades aparecer\u00e1n posicionadas sobre el perfil.<\/p>\n\n\n\n<p>Tomemos como ejemplo una capa de edificios (BDTopo) de tipo pol\u00edgonoZ.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"338\" data-attachment-id=\"10558\" data-permalink=\"https:\/\/www.sigterritoires.fr\/index.php\/comment-faire-un-profil-topographique-avec-qgis-3-26-3eme-partie\/c1-1\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?fit=2560%2C1351&ssl=1\" data-orig-size=\"2560,1351\" data-comments-opened=\"1\" data-image-meta=\"{"aperture":"0","credit":"","camera":"","caption":"","created_timestamp":"0","copyright":"","focal_length":"0","iso":"0","shutter_speed":"0","title":"","orientation":"0"}\" data-image-title=\"c1-1\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?fit=640%2C338&ssl=1\" src=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1.jpg?resize=640%2C338&ssl=1\" alt=\"\" class=\"wp-image-10558\" srcset=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?resize=1024%2C540&ssl=1 1024w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?resize=300%2C158&ssl=1 300w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?resize=768%2C405&ssl=1 768w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?resize=1536%2C810&ssl=1 1536w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?resize=2048%2C1080&ssl=1 2048w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?resize=150%2C79&ssl=1 150w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?resize=250%2C132&ssl=1 250w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?w=1280&ssl=1 1280w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c1-1-scaled.jpg?w=1920&ssl=1 1920w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/figure>\n\n\n\n<p>Al tratarse de una capa XYZ, las intersecciones de los edificios y la l\u00ednea de perfil aparecen posicionadas seg\u00fan su Z con el perfil del terreno derivado de las curvas de nivel (en verde).<\/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\/05\/c2-1.png?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"363\" data-attachment-id=\"10559\" data-permalink=\"https:\/\/www.sigterritoires.fr\/index.php\/comment-faire-un-profil-topographique-avec-qgis-3-26-3eme-partie\/c2-1\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c2-1.png?fit=841%2C477&ssl=1\" data-orig-size=\"841,477\" data-comments-opened=\"1\" data-image-meta=\"{"aperture":"0","credit":"","camera":"","caption":"","created_timestamp":"0","copyright":"","focal_length":"0","iso":"0","shutter_speed":"0","title":"","orientation":"0"}\" data-image-title=\"c2-1\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c2-1.png?fit=640%2C363&ssl=1\" src=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c2-1.png?resize=640%2C363&ssl=1\" alt=\"\" class=\"wp-image-10559\" srcset=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c2-1.png?w=841&ssl=1 841w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c2-1.png?resize=300%2C170&ssl=1 300w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c2-1.png?resize=768%2C436&ssl=1 768w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c2-1.png?resize=150%2C85&ssl=1 150w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/05\/c2-1.png?resize=250%2C142&ssl=1 250w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/figure>\n\n\n\n<p>Si el edificio no est\u00e1 posicionado en la superficie es porque, en esta capa, los edificios tienen una Z en la geometr\u00eda que corresponde a la altura media de los edificios.
