Extraction of Image Patterns(Satellite Data) for Optimization of Geochmical Sampling Design.

Category GIS & Remote sensing
Group GSI.IR
Location 20th symposium on geosciences
Holding Date 16 April 2008

     In general in order to sampling design in systemathically geochemical exploration,geological & topographic map & sometimes aeromagnetic& radiometric Data are used.
But we suggest the satellite data too (espeially high resoloution data) which can help this design
Watershed model (from elevation data) the major aim of this paper.
Watershed model with Aspect & Slope map can separate watershed & subwatershed.If watershed model has done exactly we will g the best results forstream sediment sampling.
