  1. Arizona Height Modernization Program - AZHMP Dave Minkel NGS Geodetic Advisor to Arizona Geospatial Professional, APLS

  2. Presentation Outline • Why Did We Pursue a Height Mod Grant? • Problems with the Network • Additional Benefits Expected • How Did We Get an HM Grant? • Activities • Documents • What Do We Plan to Do Under AZHMP? • Long-term Plan • Near-term Plan • Long-term Plan for AZHMP

  3. Why Did AZ Pursue a Height Mod Grant? • Vertical Control Network Issues • Dated • Latest “Campaign” Leveling in 1992 • Not All Marks are NAVD 88

  4. Why Did AZ Pursue a Height Mod Grant? • Vertical Control Network Issues • Dated • Latest “Campaign” Leveling in 1992 • Not All Marks are NAVD 88 • Subsidence

  5. 1967 - 1980; Elevation Change DU01050 -2.302 ft DU01051 -2.282 ft 0.73 miles 2006 – Elevation Change (error) could be double, i.e. -4.604 ft & -4.564 ft, from published 1980 elevation (last year of leveling)

  6. Why Did AZ Pursue a Height Mod Grant? • Vertical Control Network Issues • Dated • Latest “Campaign” Leveling in 1992 • Not All Marks are NAVD 88 • Subsidence • Sparse Where We Need It • Development = Bulldozers = Lost Marks • Additional Benefits • Tie the PLSS to the Network • GDACS Project

  7. How Did AZ Get a HM Grant? • Activities • HM Forum in 2004 • Congressional Delegation Briefings • AZ State Cartographer & Private Sector Representatives • Local and D.C. Offices Visited • Consider Congressional Schedule • Documents • AZHMP 3-Ring Binder • Discuss APPLICATIONS & BENEFITS to the Public, not what you’re going to do! • AZHMP 1-Pagers (Leave Behinds) • 10-Year Plan • AZHMP Web Site • http://agic.az.gov/hm/

  8. What Do We Plan to Do Under AZHMP? • Long-term (10-Year) Plan • Arizona Spatial Reference Center • AZCORS (CORS/COBS) • GPS Statewide Network (≈ 3800 stations) • Uses GDACS Model (i.e. near PLSS Corners) • Leveling • Analysis of Network • Leveling • Support/Research

  9. AZHMP 10-Year Plan

  10. What Do We Plan to Do Under AZHMP? • Long-term (10-Year) Plan • Arizona Spatial Reference Center • AZCORS (CORS/COBS) • GPS Statewide Network (3800 stations) • Leveling • Analysis of Network • Leveling • Support/Research • Near-term Plan (FY06 Funding) • Establish AZCORS

  11. Long-term Plan for AZHMP • Build Partnerships with Federal, State and Local Agencies • Utilize Partner Resources to Implement AZHMP and Gain Additional Program Support • Seek Additional Funding Sources • FEMA Grant(s) • Demonstrate and Document Public Benefits of AZHMP • Migrate AZHMP from Grant-based Funding to State Programmatic Funding

  12. Do You Need a HM Grant to Move Forward? • Gila County • Approximately 122 Stations set • FEMA partnership on Tonto Basin saved ~ $265K – 30 sq. mi. • 28% savings on aerial mapping costs • Cochise County • Approximately 138 Stations Set • Requiring ties to network for County GIS • 38 Stations in Last Survey • 2 Companies Turned Down
