| Abstract: | Developments of raster data capture technologies and demands from application fields call for advanced raster data analysis methods.Automatic algorithms often cannot well support this need due to the complexity of geographical phenomenon and limitations of algorithms themselves.Geo-visual analytics that involve human's visual analytical capability in data analysis attracts attention in recent years.However,Raster datasets usually have large amount of pixels,which may cause serious clotting problem in visual... |
