A Definition of GIS
GIS is a System of computer software, hardware
and data, and personnel to help manipulate,
analyze and present information that is tied to a
spatial location spatial location usually
a geographic location information
visualization of analysis of data system
linking software, hardware, data personnel a
thinking explorer who is key to the power of GIS
7
Geographic Information Systems

• A method to visualize, manipulate, analyze and
  display spatial data
• Smart Maps that link databases to a map
• How many, what kinds, where are they?
• Combine data from many different sources
• 80 of all data has some spatial component

8
Data Data Data

• Location Data
• How many What kind Where
• Scale of Data
• Local to Global
• Data Presentation
• Words, Charts, Graphs, Tables or Maps

Exploring Data with GIS turns data
into Information into knowledge
9
What is NOT GIS

• GPS Global Positioning System
• A Static Map Paper or Digital
• Maps are often a product of GIS
• A way to visualize the Analysis
• A Software Package

10
Database Not Easy to Interpret
11
Visualization Worth a Thousand Words
12
Two Ways to Input and Visualize Data

• Raster Grid
• pixels
• A location and value
• Satellite image and aerial photos are in this
  format

• Vector Linear
• Points, Lines Polygons
• Features (house,lake, etc)
• Attributes
• size, type, length, etc.

13
Sources of Data

• All departments contribute
• One central repository
• Ease of sharing
• Ease of maintenance
• Other agencies
• Vendors

14
Geographic Inquiry means

• Knowing where
• Seeing Patterns
• Finding Relationships
• Querying Geography
• Monitoring Change
• Linking Observation and Research

15
Introduction to Geocoding
16
Geocoding Primer

• Each line has specific attributes (columns)
• Street name, number, direction, lzip, rzip
• Line direction is important
• Use accurate address ranges to prevent stacking
• Interpolation is used for placement of
  approximate address

Adding other attributes

• Maintain Area, District, Beat, etc
• Done to minimize maintenance
• One file to import
• Two passes through one file
• for hundred block
• for intersection
• Zip codes versus Jurisdictions

Using GIS to Update the SafetyNet CAD Geofile
23
CAD GEOFILE GIS Interface

• Originally tried to match events
• Poor match rate 50-60
• Inconsistent addresses
• Spatial and tabular alignment necessary

24
CAD GEOFILE GIS Interface (continued)

• Street Centerlines used to update GEOFILE
• Contains address ranges and area/district
  information
• Key to standardizing addresses
• Improves quality of spatial and tabular data
• Get 99.5 match rate
• Improves quality of other geocoding applications
• Simplest way to turn tabular data into spatial
  data

25
Updating the Geofile things to be aware of

• Does not delete records
• Intersections 2 way vs 3 way
• Matching nodes create intersections
• Change in the beginning block number creates a
  new Geofile record.
• May be overlapping
• Does not change AD types
• BOLO verify to HB
• AD verified to HB
• Continued

26
Things to be aware of (continued)

• Modifying AD does not check to HB for area,
  district, beat, zip code

27
Updating the Geofile

• Still do some manual corrections but then update
  the street centerlines
• Somewhat manual process hope to fully integrate
• Very quick to update when boundaries change

28
How do you get started?

• Street Centerlines are a must
• Several Vendors sell accurate streets files
• Mark Boundaries for beats, areas districts etc
• Match against current events
• Make corrections as necessary

29
Geocoding Conclusions

• Simplified from our first methodology
• Build a better match rate the is constantly
  improving
• Changing area, district, beat boundaries is
  visual and much simpler
• Improved quality for other geocoding applications
• Not as scary as it might sound

30
Automated Vehicle Locations

• Using GPS in your vehicles

31
Automated Vehicle Locations

• Need to have accurate ambulance locations
• Initially used CDPD now GPRS and DataRadio
• GPS option was inexpensive
• GPS Accuracy
• /- 15 foot position quality
• Differential Corrections not necessary
• DoD Selective Availability
• Easy to setup each vehicle.
• Side benefits Unit recommendation, unit/event
  analysis, and pursuit path analyses

32
DataRadio/GPRS GPS AVL Equipment
DataRadio Antenna
GPS(and/or GPRS) Antenna
33
AVL Server

• Single, central application
• Receives and processes all GPS messages
• Displays GPS status of units
• Allows for configuration of units remotely
• Cannot configure DataRadio GPS
• Forwards location information to CAD server and
  other locations if needed.

GPS ComparisonGPRS vs DataRadio

• Different GPS vendors
• GPRS Sierra Wireless is Trimble TAIP
• DataRadio is Ashtech NMEA
• Sierra Wireless
• Easy to adjust GPS frequency
• Spotty coverage area
• DataRadio OOB Out of Band
• Bundles GPS Reports in unused portion of packets

Unit Recommendations

• Methods of choosing which vehicles to send to an
  event
• General Area
• Proximity to an event
• Modeled impedance and route

Dispatched by Impedance
AM01 8.56 minutes 6.47 miles ALS7 6.40
minutes 5.77 miles
45
Impedance Routing

• Choose units by a modeled path
• Turning movements
• Road closures
• One way streets
• Show optimum calculated path
• Create driving directions for path
• Index of streets can be easily updated

46
SafetyNet Interface

• CAD Queries
• Travel times for a number of units to an address
• Driving directions for a unit to an address
• Address based on vehicles position
• Open and closing of streets (still want this)

Unit Recommendation Proofing

• Create map showing event and vehicle positions
• Circle the outermost unit dispatched.
• Any available units inside the circle?
• Results and features
• show paths taken in a pursuit
• multiple vehicles can be shown
• event and unit analysis
