Outil de Coupe et Remblai - permettre DEM comme type de fichier

JamesBurton1

Site Scan permet une surface de comparaison dans l'outil Coupe/Remblai, mais il n'accepte que les fichiers xml, ou "LandXML" comme je les ai entendus appeler. Actuellement, il n'existe aucun flux de travail pour convertir un simple DEM en LandXML. J'aimerais pouvoir utiliser les DEM comme surface de comparaison puisque c'est ce à quoi la plupart des utilisateurs SIG auront accès. <\/SPAN><\/P>

Hi @JamesBurton1 , thanks for the idea. A common workflow supported in Site Scan is to generate an initial elevation surface by processing a mission, then using that DSM or DTM as a comparison surface against a future mission, to measure changes from time 1 to time 2. Would this help in your situation?

To understand your use case some more, what is typically the source of your DEM files that you wish to use as a comparison surface?

JamesBurton1

Your common workflow would work for a site where you had lead time to do a flight prior to disturbance. For my scenario, dirt has already been moved and I want to use a DEM from another source, such as NGS or UGRC, to use as the initial elevation surface you described.

Support the ability to upload a DXF format for a 3D custom surface. Having the option to use a standard GIS raster DEM would be even better.
