An On-line Collaborative Platform for Earth Observation Scientists John Gamon Cameron Kiddle Arturo Sanchez-Azofeifa Roger Curry Benoit Rivard Nayden Markatchev Gilberto Zonta Pastorello Jr. Rob Simmonds Arie Croitoru Tingxi Tan

An on-line platform for Earth Observation Scientists
Facilitating:
Collaboration between scientists
Application access, management and sharing
Data access, management and sharing
Leveraging:
Web 2.0 and social networking technologies
Cloud computing technologies
Semantic Web technologies
Funded by:
CANARIE - Network Enabled Platform (NEP-1) program
Cybera
( http://geochronos.org/ ) AGU 091214

Motivation
Scientific Gateways
Aim to enable collaboration and transparent access to data and computational resources
Social Networking
Can enhance collaboration capabilities around data and applications – “ Facebook for Scientists ”
Facebook Widely adopted
> 300 million users (50% log on to Facebook on any given day)
> 1 billion chat messages per day
> 2 billion photos, 14 million videos uploaded per month
> 350 thousand applications on Facebook Platform
AGU 091214

Based around “Groups” with common interests
Technology
Portal built on top of a social networking platform Elgg ( http://www.elgg.org )
Tags, bookmarks, profiles, blogs, wikis
Friends/contacts, groups
Discussions, message boards, calendars
Status, activity feeds
Interactive Applications
Cloud Computing
Collaboration AGU 091214

Dashboard AGU 091214

“ Groups” within GeoChronos AGU 091214

Groups - Example: Wireless Sensor Network Summer School AGU 091214

Interactive Application Service (IAS)
On-line, on-demand access to scientific applications
Share application sessions and data with other users
Hosted on a cloud computing platform
Use ASPEN ( http://grid.ucalgary.ca/projects/DataCentre/ )
dynamically provision virtual machines to host applications
Batch processing and automated workflow services (Work in Progress)
Handle longer running data processing tasks and simulations
Automate data workflows involving data acquisition and transformation of data into different data products more suitable for use by scientists (e.g., mosaic, reproject and subset MODIS data)
Applications AGU 091214

Application Catalogue AGU 091214

Interactive Application Service (IAS) Example - TIMESAT AGU 091214

Technology
iRODS ( http://www.irods.org/ ) for data storage/management
Semantic Web technologies such as RDF (Resource Description Framework) to link/relate data
Examples
Spectral Libraries
Store, share and browse spectral data
View spectral plots, metadata, ancillary data and maps
Manage and generate metadata for spectra
Create and share metadata schemas
Generalization of spectral library solution for other types of data (work in progress)
Data AGU 091214

Portal Usage
Over 70 users from Europe, South America and North America
Used at IAI International Wireless Sensor Networking Summer School in Edmonton in July 2009 (~40 participants)
On-going usage by Tropi-Dry community for collaboration and sharing documents
Slowly opening up portal to different communities of users as development progresses
