I’ve mentioned uncertainty several times on this blog in the past (examples one and two), so it seems appropriate to highlight the next International Symposium on Spatial Accuracy Assessment in Natural Resources and Environmental Sciences. The ninth occurrence of this biennial meeting will be hosted by the University of Leicester, UK, 20^th – 23^rd July 2010. Oral presentations, posters and discussion will address topics including:

Semantic uncertainty and vagueness
Modelling uncertainty using geostatistics
Propagation of uncertainty in GIS
Visualizing spatial uncertainty
Uncertainty in Remote Sensing
Spatiotemporal uncertainty
Accuracy and uncertainty of DEMs
Modelling scale in environmental systems
Positional uncertainty

The deadline for abstract submission is 28^th September 2009.
