Expanding Terrasolid Workflows Using LP360

Published On: September 22, 2017

TerraScan? LP360? Both?

  • TerraScan and LP360 have overlapping toolsets and some unique differences
  • When does it make sense to use one over the other; when does it make sense to use both?

Business Case

  • Offloading appropriate work to LP360 will reduce the overall software stack cost per user.
  • LP360 (Standard) (Pool) $4,800
  • TScan + TMod Bundle (5+) $6,100
  • MicroStation PowerDraft $2,500

= $8,600

  • Taking advantage of each package's unique strengths appropriately will increase efficiency and throughput.

Staffing

  • A well-trained user can produce a quality product in either package.
  • An experienced MicroStation/Terrasolid user will be hard to convince to switch just for basic tools such as editing
  • For inexperienced users, learning curve for LP360 is much lower than for MicroStation/Terrasolid.
  • Generally, CAD-based technicians are harder to recruit and cost more per hour than GIS-based technicians.
  • Core team of experienced MicroStation/Terrasolid users - power users- supported by technicians using LP360 for routine editing is one way to lower overall labor costs

Technical Differences

  • TerraScan architecture is based on reading all points into memory, providing 100% availability, but requires a file-based approach to project management (only one file open at a time for editing).
  • LP360 architecture is based on using pyramiding to provide point cloud overviews of entire project. % availability can vary, but single file-based editing is not required.
  • TerraScan can be supplemented with tools for calibration (TerraMatch) and orthophoto production (TerraPhoto).
  • TerraPhoto supports oblique imagery for mobile mapping.
  • LP360 has built-in QA/QC reviewing tools and more powerful tools for performing LAS file verification and correction (LAS File Analyst).
  • Feature editing/ compilation can be very user-preference driven, but there are noticeable differences between the two toolsets.
  • Comparing LP360 Feature Analyst tools to MicroStation:
    • Breakline compilation for hydro-enforcement is streamlined in LP360.
    • Tools are more user-friendly (subjective).
    • More options for controlling the conflation process.
    • More QA/QC tools that work directly on the features themselves.
