The Portugal Institute of Geography (IGP) has announced that the 7th International Symposium on Spatial Accuracy Assessment in Natural Resources and Environmental Sciences (Accuracy 2006) will take place in Lisbon  from 5th to 7th July 2006.

Accuracy 2006 is the 7th meeting in a series of biannual symposia organised by the Spatial Accuracy Research Group, that focuses on how to measure, model and handle uncertainty in spatial data, specifically originating from the fields of environment and natural resources. This group involves both researchers and GIS specialists who share a common interest on the use of spatial data and the management of its uncertainty.
 
The International Symposia on Spatial Accuracy Assessment in Natural Resources and Environmental Sciences have been held in diverse locations since 1994. Their aim has been to constitute a forum where experts coming from the environmental and natural resources fields, spatial statistics and geographic information science can interact, exchange views and contribute to the development of the theoretical and practical knowledge about spatial uncertainty in environmental sciences.
 
In this framework, the symposium will cover topics related with assessment, modelling, visualisation and propagation of uncertainty in spatial data and process models, with an emphasis on themes related with the environment and natural resources.
 
The deadline for submission of abstracts is 16th December 2005.
