Why we’re here
–
To talk about how spatial data and GIS technologies can
help your town
What is a Geographic
Information System (GIS)?
GIS technology integrates
common database
operations such as query
and statistical analysis
with the unique
visualization and
geographic analysis
benefits offered by maps.
Applications for Information
Technology and GIS
•
•
•
•
•
•
•
•
Zoning Changes
Records Management
Environmental Protection
Land Use Law Compliance
Census Information
Marketing – Real Estate
Assessment Information
Emergency Management
Components of a successful
GIS program
•
Identification of needs
•
Assessment of capacity
•
Application of the means to bridge this
gap
•
Identification of needs
–
It seems obvious, but it’s important to know what
you want to do before you do it!
Desktop Mapping
for presentations,
planning,
meetings, etc.
•
Identification of needs
Utility Mapping for asset management or system analysis
•
Identification of needs
Inventory/Survey existing infrastructure
•
Identification of needs
Integration of non-spatial data with spatial data
External tables
(e.g. residential
addresses)
Link to spatial info
(e.g. households in
Zoning District)
Generate
mailing list
•
Identification of needs
¾ Who is the “target audience?”
9 Internal producers and consumers of GIS
information
•
•
Departments
City council
9 External clients
•
•
•
•
Townfolk
Main Street businesses
Potential businesses
Regulatory agencies
•
Assessment of capacity
–
Figure out how far you are from your goals

Assessment of capacity
Data
•
Discovery
•
•
•
•
•
Aerial photos
Old system maps
Legacy databases
Anecdotal knowledge
Assessment
•
•
•
Formats (CAD, DBf, EBSIDIC, etc.)
Quality/accuracy
Usefulness
•
Assessment of capacity
Data
•
“Gap analysis”
• Missing data
• Inadequate coverage or quality
• Incorporate new technology (LIDAR, Infrared
imaging)
• Respond to changing regulations (source water
protection)
•
•
Putting it all together
Develop a plan
•
•
•
•
•
Phasing
Cost estimates
Timelines
Incorporation into town strategic plans
Address all the components of a GIS
•
Putting it all together
Hardware
•
Purchase or “re-purpose” existing computers,
equipment, and infrastructure
Software
•
•
Invest in appropriate software (GIS, RDBMS,
Web Servers)
Scale: Standalone to Enterprise
•
Putting it all together
People
•
•
Identify those people and departments who
have need and interest
Hire new personnel if necessary
Data
•
Creation/compilation
•
•
•
From public sources
Data conversion (scanning, projecting, etc.)
Develop data specifications for contractors
•
Putting it all together
This is
sometimes
the model
used in an
organization
•
Putting it all together
There are
benefits in
moving
toward a
more
integrated
model

Examples
•

•
Westerville, OH Police incident mapper
•
New Castle County eParcelView
Data Mapping Intergration
Laboratory (DataMIL)
Extracting Data
•
•
•
•
Zoom to the area of interest
More data becomes available as you zoom in
at a larger scale
Click the Extract Button
Select the layers that you want to extract

Natural Resources – Where
are They?
•
•
•
•
Viewing parcels that are within
close proximity of streams
What areas fall within good and
excellent ground water recharge
areas
Visualize what development best
Great Marsh
management practices could be
Coastal Wetland
applied
CAD drawings can be imported to the
GIS for varying development scenarios.Broadkill River
