Address Validation Reference Data - June 2014

Street address and county location at diagnosis are characteristically critically important elements for GIS mapping and analysis. Correct and complete geocoding to coordinate point locations (e.g., latitude/longitude) and standard data analysis areas (e.g., census tract and block) are a function of valid input in these standard NAACCR abstract fields.

The Wisconsin Cancer Reporting System has purchased licensing from the United States Postal Service (USPS) to access USA-wide zip code and street address Data (including County FIPS for addresses.) Using this authoritative reference data, the current validity of individual address zip codes, city/locality names, and county locations can be validated individually and in combination. These records can be used as visual job aids for abstractors as well as validation templates for automated edits in the field or at the central cancer registry.

American Community Survey Census Tract Data

The NAACCR GIS Committee has created a data table of commonly used demographic and socio-economic variables at the census tract level from the Census Bureau’s American Community Survey (ACS). Most variables are given as percentages of the population to facilitate geographic comparisons. ACS tract-level data are from 5-year periods and covers all of the U.S. and Puerto Rico. The data file downloads contain the tract data table in both SAS and MS Access format, a data dictionary, and a summary report. The SAS code library used to create the data tables is also available and includes a Word file describing the steps in the process.

Cluster Analysis Software Review

The GIS Committee, working with a consultant, Luc Anselin, PhD of the University of Illinois at Urbana-Champaign, selected four spatial analysis software packages to be reviewed based on the following criteria: 1) they were free and/or open source, 2) they were up-to-date and under active development, 3) they came with a manual and documentation, 4) they were downloadable from the Internet, and 5) they worked within a Microsoft Windows operating system. This report, was accepted by the NAACCR Board of Directors on August 18, 2004.

Geocoding Best Practices Guide

This Guide was authored by Daniel W. Goldberg of the University of Southern California (USC) GIS Research Laboratory, with expert input and guidance from members of the NAACCR GIS Committee. The Guide serves to centralize much of the available research and practice scholarship on these topics to provide a single, comprehensive perspective on all aspects of geocoding. Geocoding, for example, may involve the process of assigning latitude and longitude coordinates to street addresses.

The Guide is designed for a variety of users, including cancer registry staff who design geocoding systems, those who geocode cancer data, and researchers who use these data for public health research and practice. Dr. John Wilson, Director of the USC GIS Research Laboratory, notes that the Best Practices Guide “will serve as a rich reference manual for anyone who wants to inject more science and less art (uncertainty) into their geocoding tasks.

The NAACCR GIS Committee has compiled a list of geographic information systems-related web sites that can be used for educational purposes. Click the link below to download this list. Special thanks to David O'Brien from the Alaska Cancer Registry for coordinating the recent updates to this document.

SaTScan to Google Earth Conversion Tool

This program was created by the New York State Cancer Registry. The program takes output from SaTScan and reformats it for Google Earth. It has been recently updated to accommodate the most current versions of SaTScan. The user needs to have python installed, freely available from www.python.org. In addition, this program also requires EasyGUI to be placed in the same folder as Python. EasyGUI can be downloaded from http://easygui.sourceforge.net/download/version0.95/.
