Noble County’s Enterprise GIS System
Highway Management Topics 1) Driveway Permit and Speed Limit Ordinances 2) Signs and Culverts 3) Line Striping 4) Average Daily Traffic Figures 5) Bridge Layer
1.Driveway Permit and Speed Limit Ordinances Why incorporate permits and ordinances into the GIS? Document storage and preservation issues Document storage and preservation issues since 1987: 3000 permits & 10,000 supporting documents (maps, deeds, etc.) Reduce retrieval time Reduce retrieval time Increase accessibility Increase accessibility
1.Driveway Permit and Speed Limit Ordinances A.File Management System Implementation B.Field-based Hyperlinks Linking Driveway features to the File Management System C.Display Driveway Permit Information from Related Microsoft Access Databases
Where to locate the information? Where to locate the information? Highway Dept.—on a central server close to users How to store the information? How to store the information? Directory hierarchy— Directory hierarchy— one main directory, “Driveway Permits” subfolders for each year, “2008” subfolders for each permit, “NCD ” scanned permit & supporting documents What image format to use? 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 A. File Management System Implementation
What method to use to create the hyperlink? 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? What components make up a field-based hyperlink? Unique identifier—guarantees a 1 to 1 relationship; 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; 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
Driveway layer’s attribute table B. Field-based Hyperlinks Linking Driveway Features to the File Management System Unique Identifier— uniquely identifying each permit record
Map Properties Dialog Box for SHOOKViewer3C.mxd 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.
Final steps In the driveways layer properties dialog box… Set attribute field containing unique identifiers as storing hyperlinks Set attribute field containing unique identifiers as storing hyperlinks Select the “Permit_No” field as the field containing hyperlinks Select the “Permit_No” field as the field containing hyperlinks Select what the hyperlink is connecting to Select what the hyperlink is connecting to B. Field-based Hyperlinks Linking Driveway Features to the File Management System
Driveways Layer Properties Dialog Box B. Field-based Hyperlinks Linking Driveway Features to the File Management System Final settings
Driveway Popup Tip showing the folder’s pathway 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
C.Display Driveway Permit Information from Related Microsoft Access Databases Driveways Access hdserver.odc database connection A three step process… Step 1—Create OLE DB connection to MS Access database in ArcCatalog 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 2—Add the appropriate MS Access table to the map document Step 3—Create a Relate between the table and the driveways layer Step 3—Create a Relate between the table and the driveways layer
Driveways Access 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
Relate dialog box showing linking criteria Step 2—Add the appropriate MS Access table to the map document Step 3—Create a Relate between the table and the driveways layer C. Display Driveway Permit Information from Related MS Access Databases MS Access table Information Map document Information
Identify Results for a selected driveway feature C. Display Driveway Permit Information from Related MS Access Databases
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
Apply Differential Correction from 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
A. Create Routes B. Create Route Events C. 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.
Solid Stripe Attribute Table
A Route with associated Line Events
Query of Route Events
4. Average Daily Traffic
A) Make a new layer with the attributes you are interested in having for the layer.
Average Daily Traffic
Start your edit session
Make Roads your selectable layer
Select the road section you want
Copy the road section
Paste
This adds a line to the attribute table with the road section
Highlight the Length column
Left click and Calculate Geometry
Use the Length calculation
This gives the length for the roadway section
Fill in the other details and save your edits
Full County ADT’s with appropriate densities
4. Average Daily Traffic A) Make a new layer with the attributes you are interested in having for the layer. B) Set up your properties table
ADT Properties, remember to update classifications
5. Bridges
A) Convert access database to attribute table and insert in a layer.
Bridges now shown on the map
Use the identify button to look at specific information on a bridge
Make file folders and fill them with images you wish to see for the bridge
Add a hyperlink field to the table and create your relationship
Clicking a bridge hyperlink will then open the file.
Clicking on the image will allow a close look at the pages
Or Pictures
Future Uses of GIS in the Highway Department 1) Placing other permits on the GIS using the same methods as the driveway permits. 2) Requiring permits to be sent in electronic format with GPS locations for placed items. 3) Working with the local utilities to set up all existing services on the county GIS.
Future Uses of GIS in the Highway Department 4) Complete road re-classification 5) Work with the County Sheriff’s Department to place accidents on the GIS to learn our more dangerous roadway location.
