DATA VALIDATION & ACCURACY PETER JENKINS, MNDOT

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

SOUTHEAST MINNESOTA LIDAR PROJECT

S.E. MINNESOTA LIDAR PROJECT HIGHEST & LOWEST ACCURACY
9
S.W. MINNESOTA PROJECT HIGHEST & LOWEST ACCURACY
12
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
