Error de Elevación de Malla Texturizada

Question

<\/HEAD>Mi primer intento de procesar las imágenes de mi drone usando D2M y agregar la malla texturizada resultante como una instancia de <\/SPAN>IntegratedMeshLayer<\/A> a un <\/SPAN>Map<\/A> en un <\/SPAN>SceneView<\/A> dentro del js api. Parece que la capa de malla se muestra por debajo de la superficie pero aún es visible. Agradecería si alguien puede echar un vistazo y ver cuál podría ser mi problema?<\/SPAN><\/P><\/P>Gracias de antemano por su tiempo<\/SPAN><\/P><\/BODY><\/HTML>

Anthony are there any tutorials on processing workflows for drone2map?

Thanks again for your help.

Thanks for the reply Anthony,

Is there a tutorial on the proper way to set ground control points? I believe im doing it right but not certain. I would place a point on the basemap in 2d mode then open up the image table and add the corresponding point to the drone imagery. I added about four different GCP's to the corners of the project area and matched 8 points to every corresponding drone image.

I reprocessed and ended up with a textured mesh that was slanted at almost a 45 degree angle lol.

Ryan,

Because of the inaccuracies of GPS systems on drones, and how this data is collected relative to the ellipsoid, this is actually very common.

The workflow to assure your meshes are at the correct (Orthometric) elevation, you will need to add ground control points around your project area and reprocess.

Thanks

Tony
