Display Field: NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset contains catchment boundary polygons for NRFA Gauging Stations, according to the DTMGEN grids. Boundaries were produced using the TSTCD UNIX program. Outlet locations for input to TSTCD were developed by an iterative process starting from the published NRFA GS locations and moving these onto points of flow accumulation in the DTMGEN grids on a case-by-case basis. (The resulting point dataset became known as the Gauging Station DTM Locations.) This work was done by Cedric Laizé with assistance from Dave Morris and others. At present (March 2010) this dataset provides the "definitive" NRFA catchment boundaries. These may be updated in future in which case this notice shall be removed. As many NRFA catchments are nested this dataset contains overlapping polygons. It is therefore not suitable for direct input to tools such as Arcmap Zonal Statistics. To calculate statistics for all catchments either the dataset should be split into non-overlapping separate files (use FME), or an alternative statistics program that can cope with overlap should be used (Geospatial Modelling Environment, or StarSpan)
