Objectives § § § GIS Basics Geo-coding AVL Server Concepts Unit Recommendation Concepts Dispatch Mapping (Cad. GIS)

A Definition of 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

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

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

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

Database “Not Easy to Interpret”

Visualization “Worth a Thousand Words”

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.

Sources of Data § § § All departments contribute One central repository Ease of sharing Ease of maintenance Other agencies Vendors

Geographic Inquiry means delving into § § § Knowing where Seeing Patterns Finding Relationships Querying Geography Monitoring Change Linking Observation and Research

Introduction to Geocoding

Geocoding Primer § Each line has specific attributes § 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 Safety. Net CAD Geofile

CAD GEOFILE GIS Interface § Originally tried to match events – Poor match rate 50 -60% – Inconsistent addresses – Spatial and tabular alignment necessary

CAD GEOFILE GIS Interface (contd) § 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

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…

Things to be aware of… continued § Modifying AD – does not check to HB for area, district, beat, zip code…

Updating the Geofile § Still do manual corrections but then update the street centerlines § Somewhat manual process – hope to fully integrate § Very quick to update when boundaries change

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

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

Automated Vehicle Locations § § Need to have accurate ambulance locations Uses CDPD communication technology GPS option was inexpensive GPS Accuracy – +/- 15 foot position quality – Differential Corrections not necessary – Do. D Selective Availability § Easy to setup each vehicle. § Side benefits: Unit recommendation, unit/event analysis, and pursuit path analyses

CDPD GPS AVL Equipment CDPD Antenna GPS Antenna

AVL Server § § § Single, central application Receives and processes all GPS messages Displays GPS status of units Allows for configuration of units remotely Forwards location information to CAD server and other locations if needed.

Unit Recommendations § Methods of choosing which vehicles to send to an event: – General Area – Proximity to an event – Modeled impedance and route

Dispatched by Area

Dispatched by Proximity

Dispatched by Impedance AM 01 8. 56 minutes 6. 47 miles ALS 7 6. 40 minutes 5. 77 miles

Impedance Routing § 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

Safety. Net Interface § CAD Queries – Travel times for a number of units to an address – Driving directions for a unit to an address – Address based on vehicle’s position – Open and closing of streets

Reverse Geo-coding ‘=‘ triggers CAD to retrieve the last known GPS position of the unit

CADTravel Road Closure

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

Cad. GIS – Dispatch Mapping § Integrated Mapping Application – Can be used as a stand alone mapping application – Integrated with Safety. Net CAD to display events and vehicles in real time – Generically designed (not specifically for Yakima) – Each user can customize the map display
