[GRASS-user] classification of quickbird data

[Christian Röttger]

hello,

i am working on a land use classification in the Mekong delta, based on
quickbird data using Grass6.4 RC5 and have 2 questions.

The scene is in parts cloudy, especially my training area. is there an
option to do some correction to get rid of the clouds?

i already did a classification with 8 classes (about 90 sample) but i'm
not really satisfied with the result because its so inhomogeneous with
many small fractions. Is there some literature or experience how to
classify rural areas with small huts, rice paddys (mature, fallow, under
water) and mixed orchards?


thanks
christian
