    Synopsis of presentation:
  1. Malcolm Champlain started a 20 minute video presentation.
  2. Malcolm asked how people imported data into Microstation.
  3. A case history, using an ODOT example, was used to show how scanning was used for calculating earth volumes.
  4. Ryan (who had setup the laser scanning previous to the meeting) began to scan the rear portion of the room.
  5. Scan generated a "point cloud" which was shown on a laptop display, in real time, as the laser acquired data
  6. Standard survey proceedures can be used to "tie-down" information gathered from scanning to a common coordinate system.
  7. DTM's can be generated from scanned information.
  8. Scanned data has been used to acquire information about: piping, equipment, excavation and ground surfaces.
  9. There are many modules that work with Microstation and Autocad, but software from Cyra, creator of Cloudworks, a Microstation MDL used to convert scanned data to surfaces/solids, was demostrated.
  10. Further information can be found at: Pacific Survey Supply.
