DESCRIPTION:NIBIO produces Green Structure Maps (GSM) for Norway that cover
  built-up areas\, including cabin areas. GSM is a hybrid product based on 
 information from remote sensing data and detailed national vector datasets
  such as roads\, water\, buildings\, and land use. GSM contains 8 classes:
  Ground\, Shrub\, Tree\, Grey\, Road\, Water\, Building\, and Agriculture.
 \nQGIS is excellently suited for visual control of GSM. Based on the size 
 of the dataset (number of polygons)\, a significant random sample of each 
 class is selected to check whether it is correctly classified.\nYou can or
 ganize the map layers into different themes\, set up QGIS with multiple ma
 p windows showing different themes and zoom levels\, and use existing plug
 ins to jump from polygon to polygon and compare with aerial images and cod
 e whether the classification is correct or not - quickly and efficiently. 
 More comprehensive statistics can then be calculated\, and the results can
  be compared against the requirements to determine if the GSM meets the st
 andards.
