[Autodesk_sig_fr] [ACAD MAP/CIVIL] Courbe de niveau releve topographique

Message posté par : fasgya30 (fasgya30(a)gmail.com) ---------------------------------------- I've done the method of downloading a DEM from a database, generate contours on Global Mapper, QGIS or ArcGis, and upon exporting them to DXF, I can open them on Civil 3D and build a surface, but the base elevation starts from 0m so I can't work with that since I need the real elevation to match my field work. I've also tried doing it with Google Earth by building a path, saving that to .kml, make that into coordinates and elevation data through GPS Visualizer and then making a DEM from that on the above mentioned software, but this way I can only generate contours and visualize them properly as vectors, but upon generating a surface from them the coordinates, elevation and size are all over the place. ---------------------------------------- Le message est situé https://georezo.net/forum/viewtopic.php?pid=360840#p360840 Pour y répondre : autodesk_sig_fr(a)ml.georezo.net ou reply de votre messagerie Pour vous désabonner connectez-vous sur le forum puis Profil / Abonnement -- Association GeoRezo - le portail géomatique https://georezo.net
