A Table Or A Map?
What is GIS
Geographic Information Systems (GIS) Simple
Explanation A program that allows you to make
maps Complex Explanation GIS is a computer
system for capturing, storing, checking,
integrating, manipulating, analyzing and
displaying data related to positions on the
Earth's surface... GIS can relate otherwise
disparate on the basis of common geography,
revealing hidden patterns, relationships, and
trends that are not readily apparent in
spreadsheets or statistical packages, often
creating new information from existing data
resources.

2000 Census Data Beyond
Available Data Sources

• Household Characteristics (e.g. single parents,
  young couples)
• Identifying low income neighborhoods
• Housing stock tenure
• Age distribution (where do children elderly
  live)

  block group and tract
• Supplement the census data with 2007 estimates

Roughly 10,000 people
City Block
Roughly 5,000 people

Building on these Data with Issues Important to
Your Organization
Community Mapping Project

• Examples of data
• Collect your own local data on your own or
  through Full Circle
• Access to quality food
• Housing Displacement
• Homelessness
• Rates of obesity
• Rates of Asthma
• Access to medical facilities
• Access to transit
• Walkability of neighborhood
• Access to child day-care centers
• Patient locations
• Obesity
• Note necessary to keep in mind confidentiality
  requirements when working data

The Process of Collaboration with CNT
Community Mapping Project

• Meet with organization to discuss project goals
• Identify data sources
• Collecting and compiling data geographic area
  of analysis
• Provide data to CNT
• Work with data to produce maps and/or analyses
• Report findings to community group
