some explorations of the user experience

The user is offered a choice …

Search our holdings tofind data of interest?

No thanks. I know whichdata I want to work with.

Suppose the user elects to

perform a searchThe user’s experience

of ESG begins with the sign-on process.

This story board picks up after that point …

ESG will offer a search interface through which the user can discover runs of interest .

(This Story Board will not attempt to explore the ESG search experience. RDBMS and OWL/RDF options are being examined in a separate discussion.)

User constrains the search

March 2007


4

The result of a search is a list of “run-variables” (*)

(*) A “run-variable” means a variable that is output by a model run. Even if the result of a search is simply a “model run”, that search result implicitly carries along with it a list of the output variables.

User selects the run-variables of

interest

Obtain or analyze data data

Imagine a metadata summary of this experiment here …

Experiment 2The info icon

leads to human- readable metadata

Next we’ll run through a scenario for “preview mode” access to the data.

Question: Do the benefits of a preview mode justify the added complexity?

Define a new variable by applying simple

transformations (averaging, variance,

extrema, …)

Operation could be performed server-side

or client-side …

seamlessly segue from the browser

to analysis in user’s favorite desktop tool

March 2007


23

Server-side analysis available at the desktop, too

The remote dataset is just an OPeNDAP URLhttp://server/my_output

e.g. Vertical average of variable “TEMP” http://server/_expr_{my_output}{Tave=TEMP[Z=@AVE]}

Define a new variable on-the-fly

March 2007


24

Server-side analysis note:

• “Delayed evaluation”– Calculations are on-demand, “surgical”– So, despite the huge size of the data, to

the user the whole domain appears to have been transformed

March 2007


25

Query available data sets:

Query variables in data set “model_1”:

Query space-time domain:

Request a subset of data as a netCDF file:

e.g. Unix shell script access to products

>lasls http://cpu/LAS>lasls http://cpu/LAS

>lasls http://cpu/LAS model_1>lasls http://cpu/LAS model_1

>lasls http://cpu/LAS model_1 sst>lasls http://cpu/LAS model_1 sst

>lasget -x 20:60 -y 20:60 -t 11-Dec-2000 -f netcdf >lasget -x 20:60 -y 20:60 -t 11-Dec-2000 -f netcdf http://cpu/LAS model_1 sst http://cpu/LAS model_1 sst

All ESG products (well, nearly) can

also be made available through

a service interface.

In this example we show shell script access.

March 2007


26

The service interface also opens the door for special purpose UIs

This shows an example developed for K-12 students
