Moving <strong>Underground</strong><br />
• CityGML is a mature st<strong>and</strong>ard <strong>for</strong> above ground<br />
– <strong>Data</strong> model st<strong>and</strong>ard defined<br />
– <strong>Data</strong>sets widely available.<br />
– Software implementations of st<strong>and</strong>ard to exploit data model<br />
– Maturity allows focus on data quality <strong>and</strong> efficiency<br />
• <strong>Underground</strong> Infrastructure is the place to be now.<br />
– The New Frontier of modeling the entire urban manmade <strong>and</strong><br />
natural environment.<br />
– Add to CityGML to model the complete urban environment<br />
– Huge cost efficiencies will be achievable<br />

<strong>Underground</strong> Infrastructure In<strong>for</strong>mation (UGII)<br />
– Current State of Affairs –<br />
• Present UGII data quality is poor<br />
– Different data models<br />
– Stored in different ways<br />
– Different geometry <strong>and</strong> semantics<br />
• Inability to exchange UGI data<br />
– Maintainers have different purposes<br />
– Ownership, governance challenges<br />
– Interoperability issues<br />
• Costs of UGII failures are recognized<br />
– Routine excavations can be disastrous<br />
– Inefficiencies in construction<br />
– Unable to predict cascading failures<br />

Use cases <strong>and</strong> case studies<br />
Through the input of RFI responders <strong>and</strong> Workshop<br />
participants, major categories of use case were identified:<br />
• Routine street excavations*<br />
• Emergency response<br />
• Utility maintenance programs<br />
• Large scale construction projects*<br />
• Disaster planning <strong>and</strong> response*<br />
• Smart cities programs.<br />
*Priority use cases <strong>for</strong> initial model <strong>and</strong> pilot<br />

Concept Study Recommendations<br />
1. <strong>De</strong>velop interoperable common data models <strong>for</strong><br />
underground infrastructure<br />
2. Conduct research on legal, security, financial, <strong>and</strong> cultural<br />
challenges such as Return on Investment in underground<br />
data<br />
3. Conduct collaborative pilot projects to validate UGI data<br />
models <strong>and</strong> architectures <strong>for</strong> h<strong>and</strong>ling the UGI data.<br />

<strong>Underground</strong> <strong>Data</strong> <strong>Model</strong><br />
• <strong>Data</strong> model development based on Concept Study<br />
Recommendations <strong>and</strong> identified existing models<br />
– Funded by the FCNY<br />
– Per<strong>for</strong>med by Josh Lieberman, Tumbling Walls<br />
• Multiple interfaces to a common core exp<strong>and</strong> the interoperable<br />
data exchange <strong>and</strong> integration capabilities of existing vendor /<br />
contractor / utility systems<br />
• <strong>Model</strong> modularity focuses on the essential data elements <strong>for</strong> each<br />
distinct application use case, with a minimal core model to<br />
minimize challenge of initial deployment<br />
• Built first as a conceptual model to promote interoperability across<br />
multiple physical models, e.g. SQL, GML, JSON<br />
• As the basis <strong>for</strong> implementation pilot engagement, a prototype data<br />
model needs to be prepared <strong>for</strong> Pilot CfP.<br />
• <strong>Model</strong> report pending public release. NYC ETL-Plugfest 7/24-25<br />
