Statement of Need: Ortho Business PlanGeographic Information Coordinating Council
Coordinate acquisition of statewide orthoimagery at scheduled intervals
Cap turnaround at maximum of 4 years
Eliminate patchwork collection of county imagery sets of varying quality, resolution, and age
Establish a sustainable and consistent, funded Program
Make it accessible to 911 Centers and the Public
NC Geographic Information Coordinating Council vision for imagery4CGIA BackgroundNC Center for Geographic Information and Analysis Lead state agency for GISServices Program solutions for state and local governmentsCoordination Program data sharing, informed decision-making, and cost efficiencies
The lead agency for geographic information systems (GIS) services and GIS coordination for the StateServices Program provides solutions to state and local governmentsCoordination Program brings the statewide community together to promote data sharing, informed decision-making, and cost efficiencies5Statewide Ortho Program ApproachEngage end-user quality review earlyCommon platform for concurrent review
Visual consistency of imagery across study areas and Program phases
Administer a Proactive approach to project delivery rather than engage in Reactive measures to quality issues66Organizational StructureGICCAtlas Geographic DataNC Geodetic Survey Global Positioning SystemCORS Upgrade,Camera Validation andHorizontal QualityNC 911 BoardCGIAProject Manager, Contract AdministrationQBS Quality Assurance, ProductDistribution and NCOneMap Geospatial PortalWorking group for Ortho Planning:
