Tool Status
Current Work Status
Validator (Josh) is released, analytics added
Slicer (Laura) planned completion this May
Google-funded time-based search (Frank) available to try
UCD
First and foremost, think about the users
Using PDS

Prototypes
Tools
Still need to
Close the loop with analytics (this is in work)
Expand the market
Data
Data is apolitical - Marissa Mayer, Google
Results may surprise you
Data
MER - Mars or Earth time?
Many stories from past missions, particularly Viking, argued against Mars Time
A brief survey collected data from Mars Pathfinder veterans - Mars Time ok
The data told a different story than the stories
Data for UCD
Next steps
A broader, data based characterization of PDS
Participation
Data Collection
Phone interviews
In person interviews
In context observations
Role of analytics
Include broader community and potential new customers
Nature of Results
Some of this will be new knowledge
Some will be articulation of that which is known, but not always available to those who might use it
From here...
User interfaces for PDS 2010, with JPL EN
New and/or improved tools
Tools for Chuck
PDS Google
Initial work funded by proposal
Work funded for a second year
Third year funding is TBD
The Question
Make PDS “better” for who?
Google-funded work must address a broad audience
Google wants the tools to be useful for scientists
Google wants to also address a broader audience
Who are the users?
Possible audience expansion
Amateur Astronomers
Computer Graphic artists, e.g. planetarium show designers
Time-based search
An interface for search refinements based on scalar numerical values
Time is the first parameter deployed
Could also use phase angle, emission, incidence, target distance...
The Interface:Browse
Search on Feature Name
Refine
Numerical Scalar Search
Footprints
Who’s Using It?
Visitors
Visitors from Around the Globe
