1 2011 MN GISLIS PANEL DISCUSSION THURSDAY, OCT 6, 2011 LiDAR ACTIVITIES IN MINNESOTA

2 SPEAKERS: TIM LOESCH, MNDNR, PETER JENKINS, MNDOT, RON WENCL, USGS, LES EVERETT, UNIVERSITY OF MINNESOTA NANCY RADER, MN GEO,

3 STATEWIDE LiDAR COLLECT INTRODUCTION STATUS TIM LOESCH, MNDNR

4 DATA VALIDATION & ACCURACY PETER JENKINS, MNDOT

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

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

13 Questions ??? Thank You Peter Jenkins, PLS, CFedS
