  4. PETER JENKINS, MNDOT DATA VALIDATION & ACCURACY

  5. MINNESOTA ELEVATION COMMITTEE • The Committee’s position was to spend as much of the money on acquisition as possible • Independent accuracy validation was essential • How to accomplish this ? • The first project (SE Mn) was full of surveyors & engineers who were willing to help • In the SW Project it was mostly county engineers • So far in the Metro & Arrowhead it has been both • This has been a sample of the in-kind effort that we have seen from all levels of government

  6. SOUTHEAST MINNESOTA LIDAR PROJECT

  7. S.E. MINNESOTA LIDAR PROJECT HIGHEST & LOWEST ACCURACY

  8. S.W. MINNESOTA PROJECT HIGHEST & LOWEST ACCURACY

  9. CONCLUSIONS There is a consistent spread in the RMSE values between the SE and SW projects The methodology and personnel seem to have little influence in the accuracy results Terrain has only a small influence in the accuracy results The error budget in GPS is +/- 2.5 cm, which could explain most of what we see Regardless the consultants have consistently meet contract deliverable specifications

  10. Questions ??? Thank You Peter Jenkins, PLS, CFedS
