Line
The geo-data feature can exist as point, line or
polygon objects. In order to merge all the data features together before it can
be used by a domain decomposition code, the object properties for all the
features should be same. So polygons like lake feature and subsheds are
converted to polylines before they can be merged with already existing line
features like river. Figure x.x shows a schematic of the steps involved in the
algorithm.
