Set of slides
3. Plan and Schedule
Plan for the IEEE Transactions on Visualization and Computer Graphics (TVCG) Paper
1. Taxonomy of design problems developed from 100 to 200 images from TBM community
have evaluated 106, need another 100 or so images: check with Steve A., Forrest, and Bill Hargrove (map curves?).
Bill: More thoughts on conception nature of comparison
Enrico: Visualization used for communication and exploration purposes
who: Aritra and Jorge with Claudio and Enrico
methododolgy: partially described in Sect 2.1 of the vis paper???
using general design principles to evaluate the images
expand Sect 2.1 to fully describe the method for applying general vis design principles and how they were used to evaluate the images
Talk with Anna and Forrest and ??? to get more images
Compile a database of images with: intent, problem description, recommendations, communications between us and scientists
2. Need to have 5 or so figures of a diversity of types derived from the Taxonomy of Design Problems (Step #1 above)
include complexity of the image as a contributor to the diversity
3. Identify the problems and redo the images with our solutions
already have re-done two images (from March Vis paper)
4. Discuss the problems and the re-done figures
with the EVA group
5. survey the community to see if those improvements are suitable
how do we plan to present this in the manuscript? make a plan, which will guide our discussion with scientists and usability survey
6. develop guidelines / conclusions
state general visualization design principles
present best practices originating from this paper
include some info about good images found during the initial steps (Step 1 above)
The InfoVis paper plus reviews will be a good starting point for the TVCG paper.
Schedule
The schedule that we discussed for completing this paper was basically a couple of months July and August to do the main work and prepare a draft and a month September to do a careful internal review of the paper.
4. Discussion
Steve: keep activities well bounded, climate scientists; next phase (after successful completion of this activity) consider working with managers (eg, land managers); third phase perhaps consider conveying this type of information to decision makers
Actions:
1). New image examples to be collected: Bill, Steve, Anna, Christopher, Forrest, ...
2). Compile a document of current images with our (e.g. Aritra's) understanding of the messages that authors wanted to convey and share within this EVA group. Allow anyone to comment and provide feedbacks.
