Application Of Fuzzy Set Theory To Update Linear Features In Digital Mapping And GIS

Linear features are very vital parts of any GIS database. They are used to represent shorelines, roads, railways, and edges. In digital mapping environment, linear features are treated as sets of points when applying Fuzzy Set theory on them to come up with measures for closeness. Here we have applied Fuzzy Set theory to obtain a measure for the closeness of a line feature with unknown quality compared to another line with known or higher quality. Hence given two lines, we can use the maximum distance (dmax) among the data sets to indicate the frame of reference. Keywords - Linear features, GIS, digital mapping, fuzzy sets
