National Center for Engineering Strong Motion Data

• Build on, expand and further integrate the Engineering Data Center developed under CISN (CGS and USGS)

• Improve efficiency in use of State and Federal funds

• Center Management Group (parallels PMG of CISN)

• Advisory Committee (parallels this Group and SMIAC)

NCESMD• Existing EDC reviewed over several years with SMIAC

committee and subcommittees, and at engineering and seismological conferences - comments solicited, input ongoing

• Current EDC has significant engineering customer base:– 1,800 registered users, identify their data usage purpose– University instructors, students, geotechnical and structural firms, and

researchers– Nearly 5,000 downloads of data or station information in last 6

months

• => So build on the development, growth and user input

Key Elements of Engineering Data Center1) Central Product-Generating Agency

– CGS, Sacramento

– USGS, Menlo Park (possibly certain ANSS regions)2) Customers

– Engineers, engineering seismologists– Mostly not concerned with geographic boundaries– Center Goal – Effective, user friendly, one-stop shopping in viewing and

obtaining data

3) Data Source/Region– Credit important. Quality assurance of data, metadata, and maintenance

of stations is critical.

4) Funding Agencies– Partners and developers

Super Shuttle Analogy

– Currently have 6-cylinder operating fleet vehicles– To serve more customers better, need to augment vehicles with

another seat, 2 more cylinders, and a GPS system

NCESMD will increase capacity and increase functionality

Steps Needed

• Add National Web page for NCESMD• Add Regional Web page capability, solicit Region

interest in hosting Regional pages• Decisions/Actions:

– Level 1 on various servers, link to Level 2– Level 2 and above to be on multiple, parallel servers

(Akamai?)

• Load more metadata – critical to meet ANSS Performance Standards
