  3. Introduction

  4. History Historically the West Virginia Department of Transportation (WVDOT) has been utilizing geospatial (GIS, Remote Sensing, & GPS) technology for planning, analysis, and mapping purposes ever since the technology became available. In 2005 the WVDOT GIS Section was created to meet the growing needs for geospatial data and services in transportation. In 2007 the GIS Section was renamed as the GIS Unit and merged with the Highway Data Services (HDS) Unit, a program responsible for processing changes in roadway information, and the update and maintenance of the Roadway Inventory Log, to form the current Geospatial Transportation Information (GTI) Section.

  5. Program Planning & Administration Division Geospatial Transportation Information (GTI) Section Highway Data Services Unit GIS Unit - Geospatial Data Management -Geospatial Services • Roadway Inventory Log • -Roadway Statistics • -Public Certified Mileage

  6. GTI Mission & Vision Statements • Mission Statement • To improve customer service to the citizens of West Virginia by supplying the latest geospatial transportation information. • Vision Statement • The West Virginia Department of Transportation Geospatial Transportation Information (GTI) Section is committed to managing an enterprise Geospatial Information System that will improve the productivity of the West Virginia Department of Transportation, meet growing customer needs, and play a leading role in West Virginia’s geospatial community.

  7. GIS Implementation • Esri Shop • Enterprise License Agreement (ELA) • Esri Technology • Staff • 7 GIS Professionals • 2 Cartographers • 1 GIS Coordinator at District 7 • Enterprise GIS • WVDOT Enterprise GIS Roadmap • Enterprise Resource Planning (ERP)/Asset Management System

  8. Major GIS Projects in 2012 • Enterprise GIS Implementation • New Transportation GIS Data Model • District Level GIS Implementation • Workflow Manager • Transportation GIS Data Collection • (MS4, Railroad Crossings, Landslides, Outdoor Advertising, • Right-of-Way, Trails, Meta Data, etc.) • Highway Map Reproduction • Web Mapping Applications • (STIP, Park & Ride, Functional Classifications, etc.) • Mobile GIS Applications (MS4, etc.) • 3D GIS Application Development • GIS Portal Upgrade • ProjectWise Implementation • ERP/Asset Management System Implementation

  11. Automation Implementation

  12. Automation Implementation • Four Automated Data Management Operations • GTI_EDITING GDB  GTI_PUB_UTM GDB • Shapefiles GTI_PUB_UTM GDB • GTI_PUB_UTM GDB GTI_PUB_WM GDB • GTI_PUB_UTM GDB Shapefiles for Publications ArcGIS Model Builder GP1 Windows Scheduler Pythonwin GP2 Export Deploy Data Model Python Script Task GP … Improve GPn

  13. Key Issues & Solutions

  14. Database Lock • When a GDB is updated, it’s been accessed by clients (ArcGIS Desktop, ArcGIS Server, etc.). Database locks are created accordingly. • #Remove Database Locks on GTI_PUB_WM • Import pyodbc • cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=dotarcgis02;DATABASE=GTI_PUB_UTM;UID=xxxxx;PWD=xxx') • cursor = cnxn.cursor() • cursor.execute("delete FROM [GTI_PUB_UTM].[dbo].[SDE_process_information]" ) • cnxn.commit()

  15. Scheduled Task • After a Python script passes test, use Windows Scheduler to create a task so the script would run on a regular basis. • Make the task independent to individual’s login

  16. Email Notification? • If a task fails, notify the data repository manager by email • #Email • import smtplib, MIMEText • try: • … • except: • sender = 'admin@wvdohwebserver.com‘ • receivers = ['wuyueming@gmail.com', 'wu_yueming@yahoo.com'] • msg = MIMEText("The GTI_PUB_UTM_2_Web_Shapefiles script failed. Please check!") • msg['Subject'] = 'Python Script Failed' • msg['From'] = "Admin@WVDOHGISWebServer.com" • msg['Reply-to'] = "GTI Core Team" • msg['To'] = "Admin@WVDOHGISWebServer.com" • smtpObj = smtplib.SMTP('localhost') • smtpObj.sendmail(sender, receivers, msg.as_string())

  17. or Log • After a task is created, use a log file to track. • #Log • Import os, sys, time • rootFolder = r"C:\Geoprocessing Scripts\\" # This is where the log file is located • text_file = open(rootFolder + "PScriptLogFile.txt", "a") • text_file.write("\n\n") • text_file.write("Running GTI_EDITING_2_GTI_PUB_UTM.py began at " + str(time.strftime('%X %x %Z')) + ".\n\n") • try: • … • text_file.write("Running GTI_EDITING_2_GTI_PUB_UTM.py successfully ended at " + str(time.strftime('%X %x %Z')) + ".") • except: • text_file.write("Running GTI_EDITING_2_GTI_PUB_UTM.py failed at " + str(time.strftime('%X %x %Z')) + ".") • text_file.close()
