In this support video we will discuss a few strategies for extending your topo surface beyond its original extents to encapsulate the section of road where your Centerline is off the current TIN. Strategies we discussed for this include:

  • Quickly extrapolating the ground surface using Location
  • Collecting more topo survey data and adding this into the model
  • Buffering the TIN boundary and including the buffered boundary as modelled features when re-modelling the surface,
  • Manually adding extra points and including the added points when re-modelling the surface.
