The project was part funded by the National Landcare Program and managed by the Dept Lands, Planning and Environment (DLPE) from 1995 to 2005. The spatial data collated for the Victoria River Catchment report includes sub-catchment boundaries digitised using 1:100,000 (where available) and 1:250000 topographic map sheets, aerial photography and landsat imagery. The Roper River catchment was divided into 12 major sub-catchments and was further divided into 15 sub-sections. A total of 80 sites were surveyed to provide base-line descriptions and condition reports for channel type diversity, bank stability, bed stability, cover and structural diversity of riparian vegetation, width of riparian vegetation, cover of exotic vegetation and many other aspects of each site and sub-section within the Victoria River Catchment.

Polygon data topology rules applied are must not overlap, must not have gaps and each polygon has only one label. 0The Victoria River catchment and sub-section boundaries were delineated onto 1:100,000 and 1:250,000 topographic map sheets taking into account contour lines and spot heights before being digitised. The Victoria River Catchment boundary looks considerably different to the Australian Water Resources Council (AWRC) basin boundary particularly over the south east of the catchment. This area was defined using 1:250,000 topographic map sheets and probably requires further ground truthing. However, please note that the AWRC boundaries were also defined using 1:250,000 mapping.
