3 Washingtn Metr Area Transit Authrity WMATA prvides passenger transit rail, bus and paratransit services fr DC and surrunding areas f MD and VA (1,500 sq mi). Rail: 117 mi track; 91 statins; 1,100 railcars; 217M annual ridership Bus: 11,000 stps; 350 rutes; 1,480 buses; 124M annual ridership Paratransit: 600 vehicles; 2.4M annual ridership Infrastructure: Structures, track, pwer, signals, HVAC, drainage, IT netwrks, etc.

4 WMATA GIS Wh we are: An IT Divisin within WMATA Enterprise IT Prvides ne cnsistent platfrm agency-wide fr maps and data n WMATA s infrastructure, transit service netwrks, and supprt services; Is WMATA s sle and authritative repsitry fr gespatial infrmatin; Enfrces spatial data cnsistency acrss ther IT systems; A unique and critical cmpnent f WMATA s verall IT architecture, and a critical resurce fr infrastructure asset management, service planning and analysis, incident management, and public infrmatin. Staff: 12 fulltime GIS prfessinals Sftware: ESRI suite f sftware with ArcGIS Server and Oracle 12c, ArcGIS Desktp 10.1, 10.2, and number f extensins: Netwrk Analyst, Spatial Analyst, 3D Analyst, GeEvents, CityEngine, etc.

7 GIS in IT IT View GIS as a system in infrmatin management GIS is a spatial data management system GIS is an applicatin develpment platfrm GIS is cmpliant with SOA architecture and IT standards GIS supprts ther advanced IT initiatives Clud implementatin Mbile implementatin Big data implementatin

8 GIS as A System in Infrmatin Management Infrmatin Management Systems in Transit Asset and Maintenance Infrmatin (Wrk Orders) Scheduling and Operatin Infrmatin Safety Infrmatin Engineering Infrmatin Lcatin Infrmatin Business Intelligent (BI) Infrmatin Lcatin is a Cmmn Denminatr in Infrmatin Management GIS prvides Standard Lcatin Names, Lcatin Cntents and Naming Cnventins Standard Lcatin Referencing Systems and Framewrk GIS becmes an integral cmpnent in Transit Infrmatin Management GIS becmes a System Integratr acrss multiple business infrmatin systems in Transit

9 GIS as An Authritative Surce fr Lcatin Infrmatin in Transit GIS Prvides Lcatin Referencing Framewrk in Transit What is Lcatin Referencing System? Lcatin Referencing System is a set f ffice and field rules and prcedures that includes ne r mre lcatin referencing methds that defines standard lcatin cntents What are the Lcatin Referencing Methds? Crdinate Referencing Linear Referencing Address Referencing Feature Referencing (als called Cmmn Place Name Referencing) GIS Prvides Lcatin Services fr Nn-GIS Business Applicatins Standard Lcatin Names, Lcatin Hierarchy and Lcatin Cntent Definitin (Required fields fr lcatin based n lcatin referencing methds) On-line lcatin referencing methd services: Address gecding Lcatin lkup (pint r line) based n linear referencing methd Hybrid Lcatin Map Services fr Varius Lcatin Referencing Methds Address Gecding Highway Interchange Lcatin Reference Facility Lcatin Reference Track Chain Marker Lcatin Reference Reverse Lcatin Referencing by pint gemetry (click n the map)

10 Develpment f Lcatin Referencing Framewrk in GIS Linear Referencing System (LRS) Definitin: Lcatin Referencing based n linear distance Distance alng specific rute (track) and frm the defined starting pint Lcating pints and linear events alng specific rute (track) Key cmpnents LRS rute (track): track netwrk segment with spatial crdinates and measurements: e.g., track segment with chain markers LRS event: attribute tables with linear referencing data items: LRS rute identifier (track LRS segment) and measurements (Chain Maker values): incidents, assets alng track Implementatin f LRS in Transit Track Netwrk Drainage Netwrk Cmmunicatin Netwrk Pwer Netwrk Facility-Asset Spatial Data Mdel fr Feature Based Lcatin Referencing Facility as lcatin cntainer (space): e.g., Escalatr Bank Asset as lcatin ccupant: e.g., Escalatr Facility and Asset identifiers match Maxim Lcatin and Asset identifiers Highway Interchange Lcatin Referencing Highway netwrk: Interstatin rute segment, ramps and Interchange ndes Interchange Referencing hierarchy: Interstate->Directin->Cunty->Exit/Ramp
