Visualization of Geotechnical Data for Hazard Mitigation and

Disaster Response, a Practical Update

July 20, 2016

Today’s Presenters

• Moderator Ty Ortiz, Colorado Department of Transportation

• Presenter Hollie Ellis, Shannon and Wilson, Inc.

NCHRP is...

A state-driven national program

• The state DOTs, through AASHTO’s Standing Committee on Research... – Are core sponsors of NCHRP

– Suggest research topics and select final projects

– Help select investigators and guide their work through oversight panels

NCHRP delivers...

Practical, ready-to-use results • Applied research aimed at state

DOT practitioners • Often become AASHTO

standards, specifications, guides, manuals

• Can be directly applied across the spectrum of highway concerns: planning, design, construction, operation, maintenance, safety

A range of approaches and products • Traditional NCHRP reports • Syntheses of highway practice • IDEA Program • Domestic Scan Program • Quick-Response Research for

AASHTO • Other products to foster

implementation: – Research Results Digests – Legal Research Digests – Web-Only Documents and CD-ROMs

NCHRP Webinar Series • Part of TRB’s larger webinar

program • Opportunity to interact with

investigators and apply research findings.

Geotechnical data comes from many different

sources in many different formats.

Often the greatest challenge to those

responsible for hazard mitigation and disaster

response is simply accessing, viewing, and

interpreting geotechnical data in a consistent

and convenient format.
