Why Did AZ Pursue a Height Mod
Grant?
• Vertical Control Network Issues
– Dated
• Latest “Campaign” Leveling in 1992
• Not All Marks are NAVD 88
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
1967 - 1980; Elevation Change
DU01050 -2.302 ft
DU01051 -2.282 ft
2006 – Elevation Change
(error) could be double, i.e.
-4.604 ft & -4.564 ft, from
published 1980 elevation (last
year of leveling)
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
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

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
AZHMP 10-Year Plan
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
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
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
