class=\"wp-block-paragraph\">The difference in result is explained by the fact that QField uses a default digital terrain model, MAPZEN Global Terrain, which appears as this grey surface.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">QField&rsquo;s default terrain layer<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Layers with linear or point symbology, extruded or not, are displayed in front of the MAPZEN profile. Layers with \u00ab\u00a0surface below line\u00a0\u00bb symbology are displayed behind MAPZEN.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The line corresponding to the contour line is therefore visible, but the BDAlti is hidden behind the grey surface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is no option in QField to show or hide the MAPZEN profile. You can only replace it with a layer from your QGis project, at this project level.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To do this, return to the project properties window in QGis, in the terrain tab, and change the terrain type to DEM (raster layer).<\/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\/06\/b2.png?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"473\" data-attachment-id=\"10782\" data-permalink=\"https:\/\/www.sigterritoires.fr\/index.php\/comment-faire-un-profil-topographique-avec-qgis-3-26-5eme-partie-2\/b2-7\/\" data-orig-file=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?fit=2055%2C1519&amp;ssl=1\" data-orig-size=\"2055,1519\" 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=\"b2\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?fit=640%2C473&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?resize=640%2C473&#038;ssl=1\" alt=\"\" class=\"wp-image-10782\" srcset=\"https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?resize=1024%2C757&amp;ssl=1 1024w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?resize=300%2C222&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?resize=768%2C568&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?resize=1536%2C1135&amp;ssl=1 1536w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?resize=2048%2C1514&amp;ssl=1 2048w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?resize=150%2C111&amp;ssl=1 150w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?resize=203%2C150&amp;ssl=1 203w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?w=1280&amp;ssl=1 1280w, https:\/\/i0.wp.com\/www.sigterritoires.fr\/wp-content\/uploads\/2023\/06\/b2.png?w=1920&amp;ssl=1 1920w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Once you&rsquo;ve applied this option, you won&rsquo;t see any difference to your profile in QGis.
