Hello all,

I recently purchased a DJI Mavic Air 2S and using a WebODM and Dronelink setup.

I own a GIS business, and have a commercial ESRI license (view georeference outputs - orthos etc)

What process is used to generate a topo with contour lines?  I am mapping a golf course in the mountains and working toward outputs used in the commercial space and video for promotions.

Any advice is greatly appreciated.

Regards,
Chris

Hi,

Place drone pictures in a photogrametry software. Then generate point cloud. Classify ground point and generate DTM. Use your GIS to generate raster with contour.

Hi there. Thank you for bringing this query to us. The DJI Air 2S does not support the surveying and mapping function, the main reason for this is that the surveying and mapping function has high requirements for the aircraft positioning system and camera lens. Currently, DJI Mavic series drones cannot support such professional functions. You may want to check our DJI Enterprise products (such as Matrice 300 RTK/ Phantom 4 RTL). Thank you for your understanding and support.

data that a rtk survey would provide would have tolerances within a tenth. would doing all that be that tight? i cant imagine it would if your running grs of anykind ive seen ... meters away from where it was supposed to be. idk

Everything is relative, distance from the base station, lens calibration...
