Introduction

HistoryHistorically 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.

Key Issues & Solutions

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_WMImport pyodbccnxn = 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()

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

Email Notification?

If a task fails, notify the data repository manager by email

#Emailimport smtplib, MIMETexttry:

…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())

or Log

After a task is created, use a log file to track. #LogImport os, sys, timerootFolder = r"C:\Geoprocessing Scripts\\" # This is where the log file is locatedtext_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()
