1 GIS - T March 30 th, 2011 Providing the Public with Data Visualization using Google Maps Patrick Kielty and Matt Allen Pennsylvania Department of Transportation

2 Purpose Quickly and Easily create web based GIS for internal and public use.

3 Compromise Hard Copy and PDFs hours? Web Application w/ consultants months? Data Visualization Days?

4 Choosing Google Maps Federal Highway Administration (FHWA) Requirements for visualization Need to Rapidly Distribute and Display Data Up-to-date Information Accessible

5 Choosing Google Maps What we have Oracle Spatial GeoMedia ArcGIS 10 3 GIS Technicians / Analysts What we don t have ArcServer Developers / Consultants Budget

6 Choosing Google Maps Data does not change often Relatively small data sets No geoprocessing required

7 Oracle Spatial Other Options? Utilize other Agencies GeoServer However Time, money, experience, resources

8 Why so Simple?

9 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

10 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)

11 Business Use of Google Maps is Free No Consultants No Maintenance Costs 99.99% Uptime for Google Maps

12 Accessibility Maps now available on demand Accessible from any PC Reports generated dynamically

13 Accessibility Maps now available on demand Accessible from any PC Reports generated dynamically

14 Current Examples Data Visualization Accelerated Bridge Program Transportation Funding Scenarios Transportation Improvement Program (TIP) Visualization

15

16 Creating the Visualization All three parts can be customized Internet connection required for both map and data Can be used by all modern browsers

17

18 Google Map Interface Easy to Use Only requires Key Code Familiar to Users Ability to control size, location, zoom Data can be added from various sources Can use additional Google resources Imagery, Terrain, Traffic, Street View,

19 Google Map Take Advantage of Google s Tools

21 KML Creation Keyhole Markup Language KMZ is a compressed version of a KML (like a.zip file) Can be used in Google Maps, Google, Earth, Bing Maps, ArcGIS Explorer KML must be stored on an Internet server

22 KML Creation Ability to create Points, Lines, Polygons, Text, and Labels Fully customizable, can change size, color, icons, and transparency Can edit KML to include pictures, video, sounds,

23 Automation Used Model Builder for Batch Processing of: Splitting Districts Applying Symbology Exporting to KML

24 PennDOT s KML Creation Cycle Oracle Database GeoMedia ArcMap Data Visualization

26 KML Select pre-made markers Create you own using Photoshop, Illustrator, Use Formatting from ArcGIS (wysiwyg)

27

28 Web Page Design Simple design can be used as template for future projects HTML designed to work in all browsers Uses only HTML and JavaScript no complex programming

29 Requested Functionality Data can be turned on/off Navigation tool to select data based on County, Planning Partner, or Legislator Ability to print or export data Dynamic Reports provide real-time information from our Databases including funding, states, phases.
