Transcript

  1. Andrew Godwin / @andrewgodwin Hi, I’m Andrew Godwin • Python

    programmer-at-large • Geodata enthusiast • Does not (yet) own LiDAR equipment
  2. Andrew Godwin / @andrewgodwin Can be either surface or terrain

    (no buildings/plants) Digital Elevation Model
  3. Andrew Godwin / @andrewgodwin Very high resolution (cm range) Compact

    devices (planes or vehicles) Short distances
  4. Andrew Godwin / @andrewgodwin Free data in both point clouds

    and DEMs! e.g. Environment Agency, USGIS
  5. Andrew Godwin / @andrewgodwin 4 - 12 unattended hours (per

    15cm tile) Difficult to line up perfectly Has to print perfectly square!
  6. Andrew Godwin / @andrewgodwin 2 - 4 attended hours per

    10cm piece Small features hard to mill CNC mills ain't cheap
  7. Andrew Godwin / @andrewgodwin 15 minutes to cut, 15 mins

    to glue Only works for features surrounded by flat Limited detail
  8. Andrew Godwin / @andrewgodwin Less human-intensive milling Better laser cut

    feature highlighting 3D directly from point clouds Somehow getting a LiDAR scanner?!
