Type: conference-paper
Abstract: Land Monitor is a multi-agency project of the Western Australian Salinity Action Plan supported by the Natural Heritage Trust.It will provide land managers and administrators with baseline salinity and vegetation data for monitoring changes over time, and land height data from which contours accurate to two metre intervals can be produced.The Project will also provide estimates of areas at risk from secondary or future salinisation.Land Monitor will cover the 18 million hectares of agricultural area of south-west, Western Australia.Sequences of calibrated Landsat Thematic Mapper satellite images integrated with landform information derived from height data, ground truthing and other existing mapped data sets are used as the basis for monitoring changes in salinity and woody vegetation.Heights are derived on a 10m grid from stereo aerial photography flown at 1:40,000 scale, using soft-copy automatic terrain extraction (image correlation) techniques.Proposed Land Monitor products include salinity maps, predicted salinity maps, enhanced imagery, vegetation status maps and spectral / temporal statistics.These products will be available in a range of formats and scales, from paddock, farm to catchment and shire scales to suit customer needs.
