Implementation Steps
• Developing a service plan
• Acquiring hardware and software
• Obtaining and organizing data
• Developing a service policy
• Providing services
Planning the Service
Service Plan• Educate library administrators
about Geographic Information Systems & uses of GIS in Libraries
• Describe reasons for the service
• Components needed to offer service
• Policy statement
An organized collection of computer hardware, software, geographic data, & personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information.

Reasons for the Service
• User expectations
• Government agencies issuing data
• Web resources do not provide everything needed by users
Implementing the Service
Implementing the Service• Educate library administrators
about GIS, its uses and reasons for GIS in Libraries
• Components needed to offer service
• Policy statement
An organized collection of computer hardware, software, geographic data, & personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information.

Sources of GIS Data• Government Agencies
Local and County AgenciesState AgenciesFederal Agencies
• Other SourcesCommercial dataNewspapers
Local & County Data• Many city & county governments
use GIS.
• Tax Assessor - maintain property ownership & assessed values.
• Engineers & planners use it to manage and plan growth.
• Social Service Agencies use it to help develop plans for health and social services.
Local & County Data• Data available may be fee or free.
• Contact at a local city or county agency that may work with GIS (Engineer, Planner, Transportation, Information Services) can provide more information on who to contact.
State Data• State agencies - develop data and also receive or purchase Federal Data.
• Centralized State GIS Agencies.
• State agencies may share data with government agencies, educational institutions or libraries.
State Data
•Check with state GIS agency about obtaining data.
•State GIS Agency Web Sites Federal Geographic Data Committee
(FGDC): http://www.fgdc.gov National States Geographic
Information Council (NSGIC): http://www.nsgic.org
State Data
• Attribute data can be found on State Agency Web sites
• School Test Scores, Drop Out Rates, Teacher Salaries, Natality and Mortality information
• Check for numerical or tabular data that relates to geographic areas on state agency web sites
Federal Data
• Most of the data available to Libraries comes from Federal Agencies.
• Data may be available free through FDLP or Federal web sites.
• Some data must be purchased.
• Wide variety of data from many agencies.
Federal Agency Data•Census Bureau
•Natural Resources Conservation Service
•Federal Emergency Management Agency
Federal Agency Data•Environmental Protection Agency
•National Imagery & Mapping Agency
•US Geological Survey
Other Data Sources
•Commercial data
•Data in almanacs, newspapers, and textbooks can be used in a GIS.
•Must be formatted for use.
Data Manipulation• Some data may require editing
before use.
• Clipping National Atlas data sets
• Editing Census data

Instruction
GIS does not replace a
traditional Map Collection.
GIS is an expanded service of the Map Collection
GIS has helped us expand service to users at ASU
• Able to make thematic maps with Census and and other data
• Produce general and thematic maps on demand for individual users
• Provide maps as GIF images via the World Wide Web for classes
