Land Management Practices (Cropping History) in the Border Rivers-Gwydir & Namoi CMA (1998-2008) |
Abstract |
Land Management Practices for the Border Rivers-Gwydir and Namoi Catchment Management Authority (CMA) Areas in northern New South Wales. This dataset includes a base map of paddock boundaries (and paddock scale object) attributed with cropping history and other land cover information. This product builds on and finalises older cropping history mapping which involved the manual digitisation of crop paddock boundaries. This work was extended across the full extent of the two catchments using object recognitions software -'Definiens'. Polygons where attributed for presence of cropping for summer and winter cropping cycles between 1998 and 2008, as we as for other land cover and land management types.; Report: Fisher, A. & Turner. (2009). Mapping candidate native non-woody vegetation extent for the Border Rivers-Gwydir-Namoi catchments, northern New South Wales. Department of Environment, Climate Change & Water. unpublished.; ; Scale is commensurate with recommended map scale of cropping paddock boundaries (1:100,000). Polygons produced via image segmentation are of finer scale. |

Purpose |
The original crop mapping was conducted over key cotton cropping regions with BRG and Namoi catchments as part of a residual monitoring program within the old NSW Environment Protection Authority. This work was extended as part of the NSW Monitoring, Evaluation and Reporting (MER) Native Vegetation theme to provide information on the likely extent and condition of native non-woody vegetation. |

Lineage |
Image segmentation was carried out on SPOT5 (10m pixels) imagery (2004-2005) to produce vector polygons (shapefile format). Segmentation was carried out on individual tiles due to processing demands. Polygons less than 2500 sq. metres were eliminated, before tiles were merged into one shapefile.; ; Previously digitised cropping polygons were converted to raster format to remove overlapping polygons, and then converted back to shapefile format. ; ; The digitised polygons were then used to erase segmentation polygons. The two datasets were then combined, and checked for topology.; ; Refer to Fisher & Turner (2009) report for detailed methodology. The original crop mapping was conducted over key cotton cropping regions with BRG and Namoi catchments as part of a residual monitoring program within the old NSW Environment Protection Authority. This work was extended as part of the NSW Monitoring, Evaluation and Reporting (MER) Native Vegetation theme to provide information on the likely extent and condition of native non-woody vegetation. |
