WISCONSIN HEIGHT MODERNIZATION PROGRAM WESTERN REGION HEIGHT MOD WEBINAR NOVEMBER 19, 2013 1

WI-HMP OBJECTIVES 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 WESTERN REGION HEIGHT MOD WEBINAR 2013 2

HISTORY OF WI-HMP § 50% OF ALL WISCONSIN’S ORIGINAL GEODETIC CONTROL STATIONS WERE DESTROYED BY THE LATE 1980 S § 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 3

GEODETIC CONTROL STATIONS WESTERN REGION HEIGHT MOD WEBINAR 2013 4

GPS OBSERVATIONS A GNSS ANTENNA AND RECEIVER ARE USED TO COLLECT DATA FROM TWO SATELLITE CONSTELLATIONS WESTERN REGION HEIGHT MOD WEBINAR 2013 5

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

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

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

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

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

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

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

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

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