1 City of Marquette Geographic Information Systems (GIS) Global Positioning Systems (GPS) Presented by: Matthew Koss GIS Engineering Technician -

2 The main focus of my job at the City of Marquette is to keep track of city assets. City Assets and Asset Management Reporting

3 How do I keep track of city assets? Geographic Information Systems (GIS) ESRI Products Global Positioning Systems (GPS) 1 Trimble GeoXH 2 Leica CS25 s

4 Building the Database The single most demanding part of the GIS development process is building the database. This task takes the longest time, costs the most money, and requires the most effort in terms of planning and management. What makes this process easier?

5 City Geodatabase, Feature Dataset and Feature Class Examples Created my own File Geodatabase Schema Land Data.gdb Boundaries (Feature Dataset) Brush Collection (Feature Class) City Boundary (Feature Class) Collection Areas (Feature Class) DDA Districts (Feature Class) Garbage Collection (Feature Class) Hydrant Snow Removal Zones (Feature Class) Hydrant Zones (Feature Class) Landscape Maintenance (Feature Class) Neighborhoods (Feature Class) Spring Cleanup Zones (Feature Class) Subdivisions (Feature Class) TIFF Districts (Feature Class) Underground Utility District (Feature Class) Voting Districts (Feature Class) Used the ESRI Local Government File Geodatabase Schema for all City Infrastructure Data Sanitary Infrastructure.gdb Sewer Stormwater (Feature Dataset) sscleanout (Feature Class) ssdetention (Feature Class) ssgravitymain (Feature Class) ssinlet (Feature Class) sslateralline (Feature Class) ssmanhole (Feature Class) ssopendrain (Feature Class) sspressurizedmain (Feature Class) sspump (Feature Class) sssystemvalve (Feature Class)

6 Creating/Maintaining Feature Classes The timely and accurate maintenance of feature classes is vital to the credibility of the GIS, whose layers will be shared citywide with other departments. Operational and analytical decisions will be made using these GIS layers and datasets, so their accuracy is paramount. Example A new street is designed Example The new street is constructed Example New street is surveyed/ Asbuilt drawings are created Example GIS is updated with the new info.

Street Ratings Sidewalks Trees Grass Cutting Zones Snow Removal Zones Spring Cleanup Zones Fall Cleanup Zones Garbage Pickup Zones

7 Creating/Maintaining Feature Classes 1. GPS Ground Truth Collecting Data 2. Orthophotography Heads up Digitizing Example Example Storm Manholes/Catch Basins San Manholes/Cleanouts Water Valves/Shut Offs PASER Street Ratings Sidewalks Trees Grass Cutting Zones Snow Removal Zones Spring Cleanup Zones Fall Cleanup Zones Garbage Pickup Zones Pervious/Non Pervious Surfaces 3. Database Link using Unique Identifier Example Water Let Runs/Freeze Sewer Clean Out Database Water Shut Off Database Sanitary Manhole Database Street Asphalt Depth Database

8 88 Miles of Sanitary Sewer Mains 2,075 Sanitary Manholes 10 Pumping Stations ANALYSIS 7 Miles of Sanitary Sewer Exceeds 100 Years in Age. Over the Next Ten Years,.8 Miles will Exceed this Threshold.

9 ANALYSIS 8.7 Miles of Watermain Exceeds 100 Years In Age. Over The Next Ten Years, 1.6 Miles Will Exceed This Threshold Miles of Watermain 884 Fire Hydrants 3,129 Gate Valves 3 Pump Stations 2 Storage Tanks

10 52.6 Miles of Storm Sewer 1,378 Manholes 2,560 Catchbasins 5 Treatment Structures 11 Detention Ponds 2.6 Miles of Ditches

11 90.3 Miles of Streets ANALYSIS 45 Year Lifespan With Preventative Maintenance Miles of Streets Will Need Preventive Maintenance Miles of Streets Will Need Mill/Overlay. 8.8 Miles of Streets That Need Total Reconstruction.

12 67.6 Miles of Sidewalk

13 931 Handicap Accessible Ramps

14 18.1 Miles of Multi Use Paths

15 7 Bridges

16 Lets go through an example of how a future project location is added to the City of Marquette s Capital Improvement Plan (CIP) Example 300 East Crescent Street

Water Main Size = 6" Material = Sand Cast Year = 1915 (Corrosion/Poor Fire Flows) Water Laterals (Leaking/Corrosion/Galvanized) Sanitary Main Size = 8" Material = Clay Year = 1901 (Water

24 Water Main Size = 6" Material = Sand Cast Year = 1915 (Corrosion/Poor Fire Flows) Water Laterals (Leaking/Corrosion/Galvanized) Sanitary Main Size = 8" Material = Clay Year = 1901 (Water Infiltration/Tree Roots) Storm Size = 21" Material = Reinforced Concrete Pipe Year = 1985 (Collapse) (PASER) Rating = 4 Point Repairs (3 Problem Areas) Sidewalk (Poor Condition, Tree Roots) Curbing (Missing Or In Poor Condition)

25 Demonstration Things that make my life easier at the City 1. Geodatabases 2. Attachments 3. Data Driven Pages / Map Booklets 4. ArcGIS for Silverlight / ArcGIS for Java Script 5. GPS Leica CS25
