Vectorized version of the Land Monitor Salinity Extent – South West of Western Australia 1990 dataset. Salinity mapped in raster format with 25-m pixels. The Land Monitor salinity mapping process uses satellite imagery, high-resolution topographic data, ground information and ancillary GIS data sets to map areas of severely salt-affected land identified in consecutive satellite (Landsat TM) scenes (Furby et al 2010). To update the 1990 and 1998 estimates, the spatial-temporal methodology was re-applied using the same approach but took advantage of the latest data and improved computational resources (Caccetta et al 2022). Any changes in the extent of salt affected land detected by Land Monitor in the updated salinity mapping are most likely within the severe salinity class and may represent either expansions of this class of salinity or improvements in the condition of severely salt affected land or in the reduction of commission errors (compared to the original mapping). This data has converted the salt effected areas to a vector geodatabase. Additional post processing to remove urban areas has been applied.
