arcgis desktop - Error message using sDNA Integral Analysis . . . In other words, ArcGIS is providing sDNA with data which somehow doesn't have a shape at all Is it possible the input shapefile gdb is somehow corrupted? I haven't tried sDNA on ArcGIS 10 5 yet however the relevant parts of the interface look unchanged, and like you said it was working earlier
Modelling elevation in 3D link-network for sDNA in ArcMap I have a 3D link network model (multiple grades levels joined by vertical links) that I would like to analyze using sDNA Since the topography is uneven, I would like to account for the terrain bef
error - sDNA - Geographic Information Systems Stack Exchange Does sDNA have an upper limit of Geodesics it can calculate and store, or is the problem likely elsewhere? I am running sDNA on a MacPro M1 and Windows 11 Parallels skipzeroweightorigins and skipzeroweightdestinations is set
sDNA: tolerance problem - Geographic Information Systems Stack Exchange If you run sDNA prepare again and ask it to detect (not repair) endpoint near misses on your input data - does it find any? Is the data projected to a coordinate system that uses metres as the spatial unit - your config shows a tolerance of 0 001 which would make sense if so, though if you were using degrees you would likely trigger this warning as many links will be smaller than 0 001° If

Network Quantity Penalized of Distance in sDNA I'm following up on a question asked on the calculation of the Network Quantity Penalized of Distance (NQPD) with sDNA I can calculate the value for the link asked in Why my calculated NQPD valu
