1 BlogMyData A Virtual Research Environment for collaborative visualization of environmental data Andrew Milsted, Jeremy Frey Department of Chemistry, University of Southampton Jon Blower, Adit Santokhee Reading e-Science Centre, University of Reading

2 How do scientists collaborate day-to-day? Scholarly literature Face-to-face meetings Informal discussions Artefacts very basic: – PDFs – Static images “Lowest common denominator” approach Context is lost Preservation is ad-hoc

3 Combines web-based visualization… With a blog engine… To create a VRE for collaborative interpretation of data + = What do you think is going on Looks like a bug in the Could be a bad observation. I’ll overlay the obs database.

4 4 Godiva2 Interactively explore 4D geospatial raster datasets on the web ~40 datasets – Research data, operational forecasts, satellite products Images generated dynamically for maximum flexibility Hides technical complexity of the data from the users

5 The blog (LabTrove) Web-based blogging tool specifically designed for the practising scientist – Originally designed for lab chemist Collaboration tool for enabling discussions – Blogs can be private or public Colleagues add comments and link blog posts together Version-controlled – Nothing can be deleted, but can be updated Sophisticated metadata framework – We added geo-tagging

6 LabTrove Geo database Godiva2 sites RSS GeoRSS

7 Illustrative use cases Postdoc/PhD student: – Discover an interesting feature in a dataset – Post a blog entry asking a question Colleague at a different institute – Discovers others working on same dataset and/or same geographic area – Discovers blog entry, posts explanatory comment PI/Manager: – Views “hot topics” feed (most active discussions)

8 Feature summary Create blog entries about different kinds of visualizations – Chiefly map plots and animations so far Doesn’t store any data: just metadata and links Can highlight a point of interest – “What’s going on at this location?” Lots of metadata automatically captured – User dataset, variable, plot type – Geospatial and temporal context – Posts can be filtered on this metadata – Original visualization can be regenerated Proof of concept! (for now)

11 Metadata captured automatically and used in filtering Click on screenshot to load data in Godiva2

12 User feedback guided development Privacy controls essential – We could give even more control in future “Content is king” – Prototype system needs to contain interesting data! Animations difficult to handle but big attraction for users

13 13 Future work Prototype was developed quickly: needs “hardening” Increase the number of plot types – Vertical profiles, timeseries Improve playback of animations in browsers – HTML5??? Improve use of filtering – E.g. “Who else is working on density anomalies in the North Atlantic?” – What are the hot topics of the last week? KML and GeoRSS output for all types of visualization – E.g. for Google Earth overlays Finer-grained security?
