State GIS Coordinator Comments

• Vertical and Horizontal Elevation Accuracy is
  important to all aspects of GIS/GT
• PA is behind other states in many areas, this is
  one where we can take a lead
• DEM and Height Modernization projects will
  provide basis for accurate orthophotography,
  flood mapping, surveying, GPS fieldwork, mine
  subsidence and sinkhole monitoring, etc.

State GIS Coordinator Comments

• Flooding PAs 1 Hazard
• PA Flood Insurance Program
• All Hazards Mapping
• River Basin Mapping/Inundation Model needed
• State DEM
• 30 m DEM is not current, not accurate enough
• DEM created 10 years old, elevation data from
  quad sheet contours 70s??
• 10m DEM more granular, same bad data
• State standards call for statewide 5 contours

Current GT State Initiatives - Data

• PAMAP Orthophotography Program 3 year cycle for
  all counties in state
• DEM/Height Modernization for better GT mapping
  and product accuracy feds, state, counties,
  locals all need
• Parcels
• Roads
• Streams
• Buildings

Current GT State Initiatives

• Imagery
• 2004 USDA NAIP Imagery statewide, 1m pixels,
  112000 scale, CIR, leaf on (July)
• PAMAP at worst, 2 pixels, 12400 scale
• Enterprise GT Data Architecture
• Statewide Weather Project
• PGDSS Standards
• Commonwealth GT Strategic Plan
• Enterprise GDT License?

State GIS Coordinator Summary

• We have major problems in PA that require better
  GT data and positional accuracy
• Elevation Accuracy is of critical importance
• Elevation drives all field mapping, all imagery
  collection projects, and will support the DEM
  project
• PA has an opportunity to lead our region in the
  Height Modernization arena
• We have a great team to solve this problem
