Your neighbor's phone numbers
Looks like they’ve geocoded the entire white pages – this could be good in case of emergency, but not great from a privacy perspective (although I’ve seen a lot worse on other site):

I was the keynote for the 2nd day of the recent 1st International Geocoding Conference which was a great conference hosted by USC and ESRI this week. I thought I would pass along the discussion about our address program as well as a method to find false matches in geocoding: Using GIS to improve Addressing – Geospatial Address Summit 2011_12 (.pdf)
It’s local here in Redlands, CA and it’s FREE! Summary: The University of Southern California and Esri are collaborating to hold the First International Geospatial Geocoding Conference (IGGC) at the Esri Conference Center in Redlands, CA on December 6-7 2011. This two day event aims to draw together the leading minds in academia, industry and government to discuss geocoding research, development, technology, and applications for many domains including health, intelligence, transportation, engineering, planning, emergency response, marketing, law enforcement, insurance and many others. For more information, and to register, go to the Conference website: http://geocodingconference.com  The US Locator (all dolled up). LA County maintains customized geocoding rules (actually the ESRI locator was developed by an LA County contractor many years ago, so our rules fit very well). This has helped up maintain geocoding rates about 99.6% of all addresses. With ArcGIS 10, ESRI has developed a new set of geocoders and rule systems. I took my first look at it last night – and I am very interested in what they are providing. I think it might make things easier. Especially since it has a single-line geocoder (like Google and Bing) built in. I got that working right away! For those of you who feel the desire to delve deeply into geocoding (I guess I’m one of them), I have attached the ESRI document that discusses customizing them.

I was looking for geocoding in LA County, and came across a paper by Peter Fonda-Bonardi (the County’s acknowledged expert in Addressing). Click here to see the paper The first paragraph (written in 1994): The County of Los Angeles (LAC) and its adjacent public agencies use at least sixty (60) different house numbering systems (HNSs) to assign addresses to streets and buildings. An unknown number of private house numbering systems assign addresses to commercial complexes, mobile home parks, and gated tracts. Other addressing systems locate callboxes along freeways, mileposts along highways and railways, stations along rivers and flood channels, aqueducts, pipelines, or power lines. The use of so many HNSs leads to many duplicate street names and address ranges, which complicate the construction of address reference file and automated geocoding. This document is an initial inventory and technical description of the County’s publicly-maintained HNSs, including an HNS attribute table useful for the automated editing of topological address reference files such as TIGER. State Technology Update – December 15, 2010 OCIO Issues Policy to Boost Geographic Mapping Resources for California Government The Office of the State Chief Information Officer (OCIO) today issued a policy requiring all executive branch agencies to geocode databases or applications related to providing social services, law enforcement, economic development, tax collection and emergency response. The new policy simply requires that, where an address exists, latitude and longitude coordinates are to be included as geographic data so they can be compared and analyzed to develop new information sources for state programs. The requirement is outlined in Information Technology Policy Letter (ITPL) 10-15<http://test-www.cio.ca.gov/Government/IT_Policy/ITPL.html> released by the OCIO today to provide guidelines for agencies to follow various Enterprise Architecture standards and processes. “By comparing new sets of geographic data, agencies will be able to discover new patterns of activity to help solve problems across the state. For example, by comparing the frequency and location of illnesses to toxic waste sites, maps can be developed to better understand any correlations,” said Christy Quinlan, Acting State Chief Information Officer. “The state has a tremendous amount of data that can be leveraged to improve our understanding of what is happening in cities and neighborhoods throughout California.” The policy applies to new databases and IT projects approved after July 1, 2010 and to existing systems as they are updated over time. Many departments are already implementing geocoding features in new and existing applications as California has a number of active Geospatial Information Systems. California is among the first in the nation to require geocoding for IT projects that contain address information. Information Technology Policy Letter (ITPL) 10-15 also outlines requirements and process to assist agencies with their efforts to standardizing software, security and other IT consolidation-related activities. Additional details regarding the standards and practices released today can be found in Sections 58D and 158 in the Statewide Information Management Manual at http://www.cio.ca.gov/Government/IT_Policy/SIMM.html. When the OCIO was established in January 2008, it was the intent of the Legislature and Governor to create an agency that, among other things, establishes policies and standards to ensure that state information technology systems run effectively. Through changes to the State Administrative Manual and the Statewide Information Management Manual, the OCIO creates statewide policy for the executive branch to ensure coordination as the agency works to oversee IT activities with a common direction and vision. Please note that effective January 1, 2011, the Office of the State Chief Information Officer is renamed the California Technology Agency.
