Overview
PDS-Google
The goal is to use PDS data to prototype indexing and user experience technologies to enable access through Google to classes of information that are currently available only to a select class of users who understand how to use NASA’s information systems

Work to dateIn consultation with Google, decided to use Google Search Appliance
Requires appropriate meta-data
Initial validation of the approach
Used data from Clementine and MGS to demonstrate that we can generate and format data, use the GSA, get results
Initial UE design and testing

User Experience Approach
A simple search approach that allows for layered refinement
Testing Browse interface

Audience Scientists Amateur astronomers, general public Product Candidates Integration](https://reader035.vdocuments.us/reader035/viewer/2022071218/6050a07e8a765f7f43445355/html5/thumbnails/8.jpg)
User Experience ApproachIntegration - No silos, walls or barriers
No need to search by mission, instrument...
Many questions at this point
Advantages/disadvantages of integrated approach
Search vs. browse interface
Layered approach to searching to provide expert users with advanced search capabilities

Issue Resolution
We will use user testing data, rather than infinite debate, to resolve the issues of what interface(s) best serve the users
Two user tests conducted using the early prototype
Paper mockups of browse interface
Google support for UI design from analytics

Feature Based Search
User testing shows desire for feature based search, in addition to existing lat/long capabilities
PDS images correlated with planetary nomenclature database
Meta-data augmented with feature names, enables feature based search from text input

Issues
Where is data hosted?
How do we meet the needs of a broad and diverse user base from experts to novice
Is useful data returned with larger data sets
