## Basic System Architecture

## Schematic of a Typical Ontology Manager

## What will be needed as technology for:

**Access to data through data bases and the web**
**Software for data mining and data exploration**
**Software for simulating, interpreting, visualizing data**

## Who are the End Users outside the InSAR Research Community?

**Engineering**
**Education**
**Government/Policy decision makers**
**Operational/Hazards**
**Commercial **

## Issues Associated with Access to data through databases

**Standards for domestic and international missions**
**Security**
**Quality and Validation**
**Bandwidth**
**Interoperability – XML & GML**
**Content addressable storage**
**Near real time or real time**
**Rapid response tasking of satellite**

## S/w and H/w

**Data exploration and analysis**
**Higher level functionality is desirable**
**Portal architecture**
**Peer to peer**
**Collaborative**
**Error quantification**
**Graduated authentication**
**S/w development**
**Curation**
**Reliability and robustness**
**Fusion**

## Simulating, interpreting, and visualizing data

**Large scale simulation & modeling capability is needed & should be part of mission plan**
**Centralized and Grid computing resources**
**Code sharing (open source)**
**Code validation and curation**
**Reliability and robustness**

## Remaining questions

**Commercial component?**
**Operational versus Science mission?**
