1. WESTERN REGION HEIGHT MOD WEBINAR NOVEMBER 19, 2013 1

2. 2 WESTERN REGION HEIGHT MOD WEBINAR 2013 TO PROVIDE REAL-TIME, SUB 2 CM-HORIZONTAL AND VERTICAL POSITIONING STATEWIDE TWO RELIABLE, INDEPENDENT NETWORKS ARE NECESSARY TO MAKE THIS ACCURACY POSSIBLE. THE PASSIVE NETWORK IS THE GEODETIC CONTROL MONUMENTS AND THE ACTIVE NETWORK IS WISCORS

3. 3  50% OF ALL WISCONSIN’S ORIGINAL GEODETIC CONTROL STATIONS WERE DESTROYED BY THE LATE 1980S  WISDOT WAS THE RECIPIENT OF A FEDERAL GRANT TO RESTORE GEODETIC CONTROL  OVER 8,000 GEODETIC CONTROL STATIONS HAVE BEEN CONSTRUCTED THROUGHOUT THE STATE  AN IMPORTANT COMPONENT OF WI-HMP IS PRESERVING THESE CONTROL STATIONS WESTERN REGION HEIGHT MOD WEBINAR 2013

5. 5 A GNSS ANTENNA AND RECEIVER ARE USED TO COLLECT DATA FROM TWO SATELLITE CONSTELLATIONS

6. 6 WESTERN REGION HEIGHT MOD WEBINAR 2013 FROM THE ORIGINAL 80 HARN MONUMENTS, THE PRIMARY BASE STATIONS WERE OBSERVED

7. 7 WESTERN REGION HEIGHT MOD WEBINAR 2013 THE SECONDARY STATIONS WERE ESTABLISHED FROM THE PRIMARY GPS SURVEY

8. 8 WESTERN REGION HEIGHT MOD WEBINAR 2013 THEN WE DENSIFY FURTHER WITH LOCAL GPS STATIONS

9. WESTERN REGION HEIGHT MOD WEBINAR 2013 9 DIFFERENTIAL LEVELING OBSERVATIONS ARE PERFORMED

10. 10 WESTERN REGION HEIGHT MOD WEBINAR 2013  LEVEL LINES USE NEW BENCH MARKS, GPS STATIONS, AND HISTORICAL MARKS  BENCHMARKS APPROXIMATELY 3 Km APART  SURVEYED TO SECOND ORDER, CLASS I

11. 11 WESTERN REGION HEIGHT MOD WEBINAR 2013 COMBINATION OF NEW AND EXISITING VERTICAL CONTROL

12. 12 WESTERN REGION HEIGHT MOD WEBINAR 2013 LEVEL LINES CONNECT GEODETIC MONUMENTATION

13. 13 WESTERN REGION HEIGHT MOD WEBINAR 2013 THE WISCORS NETWORK THEN SITS ON THE PASSIVE NETWORK

14. 14 WESTERN REGION HEIGHT MOD WEBINAR 2013 A NETWORK OF 85 PERMANENTLY MOUNTED GPS ANTENNAS SPACED 50 KM APART ACROSS THE STATE PROVIDING HIGHLY ACCURATE CORRECTIONS IN REAL TIME
