PHIN GIS Workgroup

• Project: Business Requirements to PHIN Developers

• Audience: GIS Viewers, Users, Doers

• Base Layers: Infrastructure & Programmatic

• Operational Functionality: ARC IMS

PHIN GIS Workgroup

Challenges: Public Health vs. Info. Tech. “Wants/Needs” “Business Requirements”

Creating Wheels State Leadership?No Standards

Public Health Vision Prototype/Pilot Security/Privacy LICGF

Internet Map Server and LICGF

• No GIS Capacity at UW DoIT• Subcontract w/ UW’s Land

Information and Computer Graphics Facility (LICGF)

• Project Scope = Create a Prototype • Demonstrate Feasibility/Provide a

Deliverable (“Starting Point”)• WNV Data

NEDSS GIS Requirements

From the CDC….• Privacy, Confidentiality & Security• Geocoding• Spatial Analysis• Visualization• Technical Standards• Creating Maps/Data Export• NEDSS Base System & GIS

Architecture

A PHIN GIS Platform

PHIN GIS Features/Functionality:• Data Input• Geocoding• Data Visualization• Geospatial Analysis• Integration with NEDSS & SAS

Tools

Deliverables to DoIT

• Geodata Entry Report– Completed

• Geospatial Analysis Tools (Web-based)– Completed

• Geospatial Data Visualization– In progress

Goal of site

• Prototype to demonstrate capabilities of web mapping to a non-GIS audience– Identifying features– Querying features– Finding features

• Not intended for definitive analysis of West Nile data

Specifications

• Windows 2000 Server• Oracle 9i• ArcSDE 8.3• ArcIMS 4.1

– Customized HTML viewer

Lessons learned

• There is a need for Statewide coordination for the implementation of a geocoding system– Rural vs Urban Areas

• Data returned is only as good as data entered– Database needs to be structured to accept GIS parameters

• Street Address• GPS Coordinates• PLSS reference

– Correct data entry procedures need to be followed to obtain accurate results
