NSSI Data System Tom Heinrichs

UAF - Geographic Information Network of Alaska tom.heinrichs@alaska.edu www.gina.alaska.edu

NSSI OG: 14-Nov-2006

Workshop Objective

• Establish consensus on the NSSI data system’s functional and content requirements

Objectives of This Presentation

• Present an overview of GINA’s design suggestions for the NSSI data system, based on:– Experience with other data systems and

projects– Input from multiple previous data workshops

and Oversight and Staff presentations and feedback

• Introduce some of the questions to be answered to meet the workshop objective

System Objectives

• Why does NSSI need this system?

• What differentiates it from other existing systems?

GINA Background and Projects

• Four examples:– Alaska Fire Service imagery and hot spots– Arctic Geobotanical Atlas – Landsat 5 reception for Alaska– Statewide mapping image and elevation data

clearinghouse

“MODIS was great in detecting fires in remote locations. Almost thisentire summer we were out of resources used for detection flights, MODISfilled the gap for us.”

Data Systems: Role within NSSI

• Data systems serve every goal in the NSSI Oversight Group’s charter– Determination of information needs– Coordination– Public access

• These goals extend statewide

Fundamental Components

• Project tracking

• Literature database

• Local and traditional knowledge

• Data store

• Data discovery (metadata)

Fundamental Service

• Support decision making– By providing easier access to available

information, leading to better informed decisions

– By serving data easily ingestible by Decision Support Systems

Project Tracking

Literature Database

• Tied to geospatial location

• Literature and reports

• Copyright and proprietary issues

Local and Traditional Knowledge

• Important for local buy-in

• Integration with quantitative data not straightforward

• STG subcommittee

System Objectives

• Why does NSSI need this system?

• What differentiates it from other existing systems?

Why does NSSI need this system?

• To realize the goals:– Determination of information needs– Coordination– Public access

• To make better decisions using – Better (more complete) information– New techniques (GIS models)

• To realize savings of time and money

What differentiates this system?

• Designed to meet NSSI goals– “Agenda-less” source of data– Audit trail (litigation)– Owned by and serving the objectives of NSSI,

which are broader than any one agency’s goals

– Will lead to the service of larger, statewide goals

Topics for This Group

• Review of the proposed data layers (content);

• Discussion and comment on suggested standardized grids and projections;

• Review of the recommended system functionality; and

• Generation of a list of suggested topics/issues that could be addressed through DSS functionality.
