Lineage |
Satellite imagery from the Landsat 5 TM and Landsat 7 ETM+ sensors was the main data source used to map the different types of grasslands and grassy woodlands. NSW DEC provided an extensive point database of grassy ecosystem information collected in the study area. A dataset of 287 of accurately georeferenced sites was collected specifically for this project. This included 71 datapoints with vegetation information collected in previous years that were also utilised in the project. This extensive database of field information was used to interpret the results of the satellite image classification. NSW DEC also provided several vector data sets that were used to complete the study: The methodology to map different types of grasslands and grassy woodlands generally follows the approach used in the study "Remote Sensing Detection of Native Grasslands using Multi-Image Spectral Analysis - South Eastern Highlands of NSW". This study was completed by ERIC in 2001 for NSW NPWS. The basic steps of this methodology are: Classify the imagery to identify the non-grassland areas, such as water, urban and forest. Exclude non-grassland areas from subsequent analyses by masking them in the imagery. Classify only the grassland areas to discriminate categories such as native grassland, exotic grassland and grassy woodland. Images from autumn, winter, spring and summer are used to enhance the discrimination of the different grassland types. |
