the paper presented at the ISPRS Hanover workshop will be distributed to all participants per
email
Kressler gives a presentation on the results achieved so far, including:
methodological background (object-oriented classification)
data sets used (from the porject partners)
results for the single test sites
Discussion on:
Definition of segmentation and classification parameters
parameters have to be defined once for images of certain characteristics
no change of parameters is necessary for similar images in terms of radiometry and if similar
landscape types are covered
adaptation is required when radiometry or illumination changes (adjustment of spectral values)
or when landscape varies (new land cover types have to be added)
How to use linear features (such as road network) if not represented as polygons?
line features in the data base could be buffered according to attribute data
