Enterprise Addressing System

Why an Enterprise Addressing System (EAS)?

• Departments are focused on their primary business• Addresses critical but secondary• Current ad hoc situation leads to inefficiencies and

confusion• An enterprise solution

Current State• DBI – Issues permits for an address

– new address for a building: $262– Maintains own address database (AVS)

• 311 CSC – Creates service request for an address– Maintains own address table

• DPW – Services requests for Graffiti removal etc.; Issues permits– Maintains own set of address lists and databases

• Emergency Management – send Fire and Police to address– Maintains own address database

• Assessor – Appraises property by block and lot– Site address in Parcel Database varies in accuracy

• TTX, SFMTA, Real Estate, Recreation and Park, etc.

EAS is …

• Funded initially by COIT, now funded by SFGIS• Focused solely on address management• Shared source of address information • Available across departments• Easy to use• Adopted by DBI (Director Day at COIT 4/14)

Demonstration

• EAS 1.0 in production (eas.sfgov.org)– Production environment on VMWare– Regularly scheduled load of DBI’s data into EAS– Nightly load of parcels and streets from DPW into EAS– Active Open Source Project (http://code.google.com/eas)

• EAS 1.1– Real-time integration with DBI’s permitting system– MOU/SLA between DT and DBI

• EAS 1.2 and beyond– Integration with 311 Call Service Center database– Integration with DPW– Integration with other departments – Mail Merge services, etc.– Leverage development work of other municipalities through the EAS Open Source

Project – Civic Commons, Code for America, Sacramento, Bellevue, Virginia Beach, San Mateo

– Add imagery, building footprints

Why Open Source?

Good timing for Open Source

• Open source standards are prevalent– Web Feature Service (WFS), vector– Web Map Service (WMS), raster

• ‘Legacy’ open source paves the path– Apache most popular webserver since April 1996 – 54% websites use Apache today

• Netcraft Web Server Survey (January 2010)

Maturity of Open Source options

• Linux ~ University of Helsinki, 1991• Apache ~ NCSA, 1994• PostgreSQL ~ Cal 1970’s• PostGIS ~ Refractions Research, 2001• MapServer ~2000• Python ~1667

Cost

• Software licensing is available to the City free of charge

• Bulk of funding could go to development work and creating solution

• Free to share with other organizations (GPL3)• What about support?

– So far, not an issue; in fact a plus.– Support options available

EAS - Open Source Software• PostgreSQL/PostGIS: An Open Source, spatially enabled

relational database management system• GeoServer: An Open Source application server capable of

delivering spatial data using standard formats (such as Web Mapping Services and Web Feature Services) as specified by the Open Geospatial Consortium.

• OpenLayers: An Open Source JavaScript Library that permits the development of web mapping applications similar to Google Maps

• Django/GeoDjango: A spatially enabled Open Source web application development framework

• ExtJS: A modern javascript library (ajax, etc.)

Why use the Cloud?

• Necessity• Opportunity to evaluate offerings• Virtualized Data Center• Development to QA to Production• Hot Site potential
