PUBLIC WORKS GISStarted with 60 day trial version of Arcmap
I was hooked

PUBLIC WORKS GIS
GIS COMMITTEE1 or 2 from departments interested
Meet once per month

PUBLIC WORKS GIS
2004, RFP for GIS needs assessment
Hired PeopleGIS, Arlington, MA

PUBLIC WORKS GIS Cartographic Assoc., Littleton, NH
Parcel mapping and Created building foot print
8
PUBLIC WORKS GIS
2005, Contracted for gps locating with CAI
Water, Hydrants & valvesSewer manholes
Drainage structures & culverts
9
PUBLIC WORKS GIS
Attributes collected only for drainageLabeled water and sewer structures with
existing ID numbers

PUBLIC WORKS GIS
Purchased 2 copies of ESRI Arcmap
Public Works Dept.Planning office
12
PUBLIC WORKS GIS
Purchased Public Works Information Management software (PWIM) from CAI.
Extension for ArcmapAllows for topology
Direction of flowCurrent data stored in a Personal Geodatabase
13
PUBLIC WORKS GIS
MAPPINGUsing PWIM, mapped all water and sewer lines Based on:
➔GPS located structures➔Existing hand drawn maps
➔Plans on file➔Personal knowledge
14
PUBLIC WORKS GIS
Water and SewerUsing the ID numbers entered with collected structuresCreated a join between database and gps data for: Hydrants, Valves, & Sewer manholes
15
PUBLIC WORKS GIS
Drainage mapping
Culverts mapped with GPS, DoneCollected size, material, condition,
& flow direction
16
PUBLIC WORKS GISIn Town drainageAn on going project
Data difficult to collect
17
PUBLIC WORKS GIS
DrainageWe have:
618 Culverts 1851 Drop inlets105 Drain manholes

PUBLIC WORKS GIS
Data Maintenance
Inventive techniques without gpsField measuring, ortho use, etc
Used CAD files for a couple of larger projects
19
PUBLIC WORKS GIS
Mapped with out GPS
Sidewalks; walked all and added stop/start points visible in GISWater curb stops and service lines from office information

PUBLIC WORKS GIS
AccuracyA big concern early on
Less so over time with experience
22
PUBLIC WORKS GIS
2010 GPS Purchase
Trimble GeoXTExternal antenna
Terrasync and Pathfinder software
23
PUBLIC WORKS GIS
Map book
3 years ago produced map book direct from Arcmap, first with DsMapBook then data driven
pagesReplaces hand drawn maps
24
PUBLIC WORKS GIS
Advantages
GIS map book is a hit with crewEverything is to scale
Easier to locate structures in the fieldHelps to puzzle out unknowns
25
PUBLIC WORKS GIS
Putting pieces of data together
26
PUBLIC WORKS GIS
27
PUBLIC WORKS GIS
Highway and related mapping
Sidewalks: condition & plow routesTown Roads, Pavement condition (RSMS)
Retaining walls, GOOGLE MAPRoad plow routesCulverts, drainage, & bridges
