What is GIS?
Geographic Information System (GIS)
Visualize, analyze, and interpret spatially tied data
More strategic and informed decision making
City = location based
Communication, public outreach, access to information, record keeping
GIS helps reach organizational goals & objectives
2
Overview
GIS is multifaceted .. many applications
Outline
Data creation – Identify a need
Data management – Maintain data integrity
Analysis – What are we trying to accomplish?
Access to information – How do we disseminate information?
Cartography – Final deliverable
3
ArcMap Software
ESRI ArcGIS Software Suite
Proprietary software
Utilize ArcMap for 95% of GIS
4
Data Creation
example: Sidewalk Inventory
Need: Sidewalk Inventory
Sidewalk Condition
Replacement schedule
ADA Compliance
Aid in policy development
5
Data Creation:
example: Stormwater Catchments
3D vs 2D
Natural drainage, topography, street and storm drain infrastructure
Pervious and impervious surfaces
In house knowledge
Need: Comply with State permitting requirements
6
Data Management:
Arc Catalog
Master geodatabases – editing environment
Compressed “read-only” geodatabase
Program for file organization and management of GIS data
7
Analysis:
example: JM Pipe
Lawsuit for known PVC water main pipe failure
Analysis: Where, how much (ft), when?
With the help of Public Works Staff
Identified (where, when, how) JM PVC pipe was installed within City
Resulted in a settlement payout of $61,038.05
8
Analysis:
example: Zoning
Analysis: How many acres of Industrial Mixed Used zoned land
are within 300ft of the property line of
Ocean View Elementary School?
9
Analysis:
example: Dispatch Calls
Future analysis:
Spatial and temporal distribution of calls
Track camp migration/size
Frequency of encounters by zone
Density of calls
10
Access to Information:
Tracts in Google Earth
Google Earth Pro (free to download)
Access: Quickly locate tract and parcel map related information (i.e. easement locations)
Most GIS layers can be exported to Google Earth
11
Access to Information:
Tracts in Google Earth
Access: Simple pathway to link PDF documents stored as text field in ArcMap
12
Access to Information:
Tracts in Google Earth cont.
Access: Shows in Google Earth as a blue hyperlink
13
Access to Information:
Tracts in Google Earth cont.
Access: Pulls up comprehensive PDF document of Improvement Plans relating to specified tract
14
Access to Information:
Traffic Collisions in Google Earth
Access: Collision information can help identify patterns and trends
Type
Frequency
15
Access to Information:
Traffic Collisions in Google Earth
Access: Linked to accident report
Help identify common causes
Give insight to potential solutions
16
Cartography:
ArcMap Layout View
Cartography: Clearly portray the purpose of the map
Remember the importance of cartographic elements
17
Summary
Many applications of GIS
Many ways to use GIS data to aid in decision making
Examples given are just a fraction of what GIS has been able to do for the City
18
Potential Future Applications
Cloud-based storage for mobile access to linked documents
ArcGIS Online – interactive maps for public use
Thank you for your time!
