Abstract: This datalayer is a gridded data set of cell length, corresponding with an estimate of river length, for rivers in Plum Island Sound watershed. The resolution is 120 m x 120 m. This layer gives length of each grid cell (either as 120m if vertical or horizontal, or 169.7 if diagonal). This information is derived from the flow direction data file: WAT-RGIS-120m-FlowDirection.asc Provide length of river, uncorrected for sub grid cell meandering, which is assumed to be relativelty small.
