PennDOT Solution: New Requirements, Of Course
• Operators now required to prepare General and Winter Roadway Maintenance Plans
• Plans must include:– Detailed Schedule of Proposed Activities– Estimates of Truck Volumes on Bonded Roads
• Operators who fail to provide this information risk losing their road bonds.
The REAL Problem…
Who is Responsible for Repairs when Multiple Companies Operate on the Same Roads?
The Pennoni Solution: Collaborative GIS
Suddenly, Tracey and Damon get a new project…
• Build a GIS framework for calculating truck volumes on bonded state routes during Marcellus Shale drilling activities.
• System must be flexible: Multiple operators, multiple Districts, may includes state and local roads.
• Temporal, in addition to spatial, analysis required.
.
Oh, and by the way….
• The data is very noisy, sometimes incomplete• The data changes often – moving target• You’re not an expert in Marcellus Shale drilling procedures and
protocols? No worries, you will be soon…
• One more thing… fours days to complete or else our client losestheir road bonds.
.
Lesson #1
Maintain a good sense of humor. These challenges are the norm more often than the exception.
.
• Noisy, incomplete data
• Imperfect data that changes over time
• Domain Knowledge Learning Curve
• Client Expectations

The Pennoni Solution: Collaborative GIS
Raw data becomes…
Challenge: Inconsistent / Incomplete / Noisy Data
• Format of incoming data, quality of data, and level of details varied considerably from one company to the next.
• Big Surprise: Drill operators do not generally think like GIS and database designers.
.
Lesson #2: Generalize and Simplify Data Model
• Based on data received, our original data model was very complex.
• By inspecting the problem, however, we realized that important generalities exist in our data.
• This simplified our problem considerably!
.
Lesson #3: Standardize Data Collection
• To address data quality, Pennoni created a series of simple Excel spreadsheets which guide the operators to provide data in a more standard format.
• Not a perfect solution. Expect resistance.
• Also, we are exploring the idea of a web interface, where operators can manage their own data. This would make it truly a collaborative GIS system.
.
Challenge #2: Data Changes Frequently
• Drilling industry is defined by its fast pace and continual refinement of schedules and activities
• These changes affect productivity in ways that are often difficult for the client to understand.
• They can be frustrating for us as well. See Lesson #1: Maintain Sense of Humor.
.
Lesson #4: Learn to Automate Repetitive Tasks
We save a lot of time by automated two particularly repetitive tasks:• Querying arbitrary dates• Creating new routes
… But we had to be selective when we used these tools.
Challenge: Acquiring Domain Knowledge
• GIS has application in a myriad of industries, including Gas and Oil.
• Chances are if you’re an GIS expert, you’re probably not an expert in these other industries.
• So, how do you obtain the domain knowledge needed to design a good GIS system?
Lesson #5: Actively Involve Your Client
• Meetings• Phone Calls• Emails• Visit their workplace
• Work to understand their processes
• Help them understand your processes as well.
PennDOT would not allocate expenses between gas companies.
Lesson #6: Promote and Market Collaborative GIS
So, Pennoni hosted a meet-and-greet to encourage collaboration
Shared Pipes and Ponds
GIS can stimulate discussions for determining cost-effective solutions to traffic and resource challenges
Shared cost for roadway monitoring, roadway repair, water treatment, reuse and distribution
Collaborative GIS = Shared Resources
