Practical Applications forHighway Infrastructure and Asset Management Prepared by: Steven J. Hook, Noble County GIS Coordinator 101 N Orange St. Courthouse, 4th Floor Albion, IN 46701 And Keith A. Lytton P.E., Noble County Highway Engineer 1118 E Main St. Albion, IN 46701
Noble County, Indiana • Demographics • Rural County northwest of Fort Wayne • Population of 48,000 • Approximately 411 sq. miles • Brief GIS History • Contracted with Sanborn (Orthos) and Schneider (GIS) 2002-2003 • GIS system in use since spring 2005 • GIS website in use since summer 2006 • Replaced parcel mapping redundancy among three offices
Noble County GIS History • 1980’s—PLSS grid created • 1990’s—Cadastral layers created using AutoCAD (with FMS) • 2003—GIS project funded: Color Orthophotography Planimetric layers Convert dwg cadastral layers to ArcGIS • 2005—Color orthophotography (State); Schneider GIS Award for Excellence • 2006—IGIC Award for Excellence (Counties Category) • 2008—Pictometry color oblique/orthophotography
GIS Working Environment • Use ESRI and AutoCAD products ArcGIS Desktop 9.2—ArcEditor, ArcView, & ArcReader AutoCAD Map 3D 2008 & Civil Desktop 2007 AutoCAD LT • GIS data storage 2—MS SQL 2005 ArcSDE geodatabases: feature classes & orthophotography shapefiles & dwg files
Driveway Permit and Speed Limit Ordinances Signs and Culverts Line Striping Average Daily Traffic Figures Bridge Layer Highway Management Topics
1. Driveway Permit and Speed Limit Ordinances • Why incorporate permits and ordinances into the GIS? • Document storage and preservation issues • since 1987: 3000 permits & • 10,000 supporting documents • (maps, deeds, etc.) • Reduce retrieval time • Increase accessibility
1. Driveway Permit and Speed Limit Ordinances • A. File Management System Implementation • Field-based Hyperlinks Linking Driveway features to the File Management System • C. Display Driveway Permit Information from Related Microsoft Access Databases
A. File Management System Implementation • Where to locate the information? Highway Dept.—on a central server close to users • How to store the information? Directory hierarchy— one main directory, “Driveway Permits” subfolders for each year, “2008” subfolders for each permit, “NCD-001-08” scanned permit & supporting documents • What image format to use? Documents scanned using a TIFF format— standard format, stable, and non-proprietary
A. File Management System Implementation Driveway permit file management system
B. Field-based Hyperlinks Linking Driveway Features to the File Management System • What method to use to create the hyperlink? Link to a document, URL, or attribute field Field-based vs. dynamic hyperlinks • What components make up a field-based hyperlink? Unique identifier—guarantees a 1 to 1 relationship; value stored in the driveway attribute table “Permit_No” field Hyperlink Base—pathname to the scanned documents; value stored in the hyperlink base (Map Properties dialog box)
B. Field-based Hyperlinks Linking Driveway Features to the File Management System Unique Identifier— uniquely identifying each permit record Driveway layer’s attribute table
B. Field-based Hyperlinks Linking Driveway Features to the File Management System Hyperlink Base— pathway to the permit folders stored on the Highway server; eliminates need to store full pathname along with the unique identifier, reducing redundancy. Map Properties Dialog Box for SHOOKViewer3C.mxd
B. Field-based Hyperlinks Linking Driveway Features to the File Management System Final steps In the driveways layer properties dialog box… • Set attribute field containing unique identifiers as storing hyperlinks • Select the “Permit_No” field as the field containing hyperlinks • Select what the hyperlink is connecting to
B. Field-based Hyperlinks Linking Driveway Features to the File Management System Final settings Driveways Layer Properties Dialog Box
B. Field-based Hyperlinks Linking Driveway Features to the File Management System Click the hyperlink button to view driveways having hyperlinks Hold the mouse over the drive highlighted in blue to reveal hyperlink pathway Driveway Popup Tip showing the folder’s pathway
C. Display Driveway Permit Information from Related Microsoft Access Databases A three step process… • Step 1—Create OLE DB connection to MS Access database in ArcCatalog • Step 2—Add the appropriate MS Access table to the map document • Step 3—Create a Relate between the table and the driveways layer Driveways Access DB @ hdserver.odc database connection
C. Display Driveway Permit Information from Related MS Access Databases Step 1—Create OLE DB connection to MS Access database in ArcCatalog Create OLE DB connection Driveways Access DB @ hdserver.odc database connection
C. Display Driveway Permit Information from Related MS Access Databases Step 2—Add the appropriate MS Access table to the map document Step 3—Create a Relate between the table and the driveways layer Map document Information MS Access table Information Relate dialog box showing linking criteria
C. Display Driveway Permit Information from Related MS Access Databases Identify Results for a selected driveway feature
2. Signs and Culverts A. Data Acquisition B. Data Transfer to the PC C. Updating the GIS
A. Data Acquisition Trimble GeoXT’s were used to gather field data
B. Data Transfer to the PC Transfer Data from Trimble to PC using GPS Pathfinder Software
Export from GPS Pathfinder Software to ESRI ArcEditor as Shapefile
Traffic Signs are easily found by selection or performing a query.
Culverts are found the same way by query or individual identifying.
3. Line Striping • Create Routes • Create Route Events • Updating GIS
A) Create Routes Create Routes Dialog Box
B) Create Route Events A Table is first created that contains all the information that will be wanted for stored information
Add route events dialog creating the SolidStripe.dbf events table.
4. Average Daily Traffic A) Make a new layer with the attributes you are interested in having for the layer.
This adds a line to the attribute table with the road section
