This report highlights the use of sensor networks in field monitoring under extreme climate conditions. It discusses the US$100 PC project, sensor network agriculture, and the Emja Glacier monitoring project near Mt. Everest, focusing on global warming monitoring.

Global Roads – AsiaWorkshop Earth Monitoring Working Group January 24, 2008
There is a dearth of openly available digital street and road data in most Asian countries.
In contrast – there is a growing abundance of satellite imagery suitable for the extraction of street and road data!See Google Earth…….
Can we assist in the development of street and road data in Asia using satellite remote sensing data?

Primary roads and some secondary roads could be identified in NASA Landsat Geocover Orthorectified data
Roads were easier to detect in 15 meter Japan ASTER orthrectified data
Recommended Approach • Ingest current decade roads data from available open sources. This forms the initial base. • Process the ASTER archive in gap areas with automated road extraction algorithms (AIST GEO Grid). • Establish web mapping service at to allow registered users (crowd sourcing) to add roads, label road names, add metadata and GPS tracks. • Explore the possible use of high spatial resolution imagery available in virtual globes (e.g. Google Earth) to generate street / road data in urban areas (crowd sourcing). • Seek funding for pilot project in Asia region. • Meet to discuss progress later in 2008.
