METHOD FOR SEARCHING WET LAND POSITION BASED ON GIS

摘要

A method for searching swamp location using GIS is provided to perceive a swamp location in real time by creating a distribution chart of the swamp and searching the swamp location correctly with a low cost. A method for searching swamp location using GIS comprises the followings of; deriving a plurality of GIS thematic maps through the GIS preprocessing(S200); deriving moisture index maps about region(S202); deriving preliminary swamp by filtering a region which has the possibility of to be the swamp(S204); giving a weighted value according to the swamp possibility(S206); selecting a expected swamp region using the weighted value(S208); selecting a swamp region based on an area and congestion(S210); extracting a search point(S212); and generating a distribution chart according to image of GIS(S214).
