GIS at SDSC• Domains:
– From geology, environmental science, hydrology, ocean biodiversity, regional development, Katrina response, archaeology, to neuroscience and ophthalmology.
• All levels of infrastructure:– Spatial databases (Oracle, MySQL, Postgres/PostGIS, ArcSDE)– Spatial servers (ArcGIS Server, ArcIMS, WMS/WFS servers)– Spatial web services, incl. spatial information integration– Client applications: COTS, open source, mashups, in-house
• Novel approaches:– Map assembly services– Ontology-aware spatial query processing– Distributed spatial data querying using mediators– Wrappers for spatial data sources of different type– XML-based vector mapping– Portal integration– SOA integration, sensor data management– Long-term spatial data preservation
• Collaborations:– Industrial partners (ESRI), associations (OGC), government agencies (USGS, EPA,
NCDC, etc.)• GIS-related funding: NSF, NIH, NIEHS, NARA, ESRI• Classes and short courses taught: from archaeology to medical sciences
