GIS - T March 30 th, 2011 Providing the Public with Data Visualization using Google Maps Patrick Kielty and Matt Allen Pennsylvania Department of Transportation
Purpose Quickly and Easily create web based GIS for internal and public use.
Compromise Hard Copy and PDFs hours? Web Application w/ consultants months? Data Visualization Days?
Choosing Google Maps Federal Highway Administration (FHWA) Requirements for visualization Need to Rapidly Distribute and Display Data Up-to-date Information Accessible
Choosing Google Maps What we have Oracle Spatial GeoMedia ArcGIS 10 3 GIS Technicians / Analysts What we don t have ArcServer Developers / Consultants Budget
Choosing Google Maps Data does not change often Relatively small data sets No geoprocessing required
Oracle Spatial Other Options? Utilize other Agencies GeoServer However Time, money, experience, resources
Why so Simple?
Benefits Easy to create Transportation Funding Scenarios created in less than 8 days Look and functionality can be modified quickly Google Maps interface is easy to use and familiar Simple steps to update, modify, add/delete data Current projects can be used as templates for future request
Benefits Shelf-Life Short Term product that can be discarded (Scenario Mapping) Temporary solution that can meet requirements until long term application is in place (TIP Visualization)
Business Use of Google Maps is Free No Consultants No Maintenance Costs 99.99% Uptime for Google Maps
Accessibility Maps now available on demand Accessible from any PC Reports generated dynamically
