Abstract
Satellite images, digital elevation maps and ground data will be used to produce maps of land condition, such as the current extent of salinity, the changes since 1990 and predictions of future salinity risk. These products, and the data they are formed from, can be used by land managers and advisers as part of the process of managing that land. Ground data are vital to extracting land condition information from satellite images. Samples of land in good, poor and salt-affected condition are needed in order to learn how to understand the variation in the satellite images. It is also necessary to understand the relationships between salinity and salinity risk and any other datasets that are available for a region, for example ‘in region X, salinity never occurs on soil type Y’. Extra ground data are needed to validate the maps that are produced and to understand what types of land condition can and cannot be mapped using satellite images. The general process for producing salinity maps is illustrated in the diagram on the next page.
