Abstract
Version 1 of the Water Theme of the Land Cover of Australia (Water25) is an ISO 19144-2 classification of the percentage of successful observations from Landsat 5 TM and Landsat 7 ETM+ sensors in which water was detected. Each satellite image pixel is an observation; Successful observations are those in which the land surface is clearly seen (unobscured by clouds for example) and quality checks are passed. Classes: - Perennial (water observed more than 75% of the time) - Non-perennial 60%-75% (water observed from 60 to 75% of the time) - Non perennial 30%-60% (water observed from 30 to 60% of the time) - Non perennial 8%-30% (water observed from 8% to 30% of the time) - Land subject to infrequent inundation 1%+ (water observed from 1% to 8% of the time) - No water observed Water25 can be used to map and characterise inland water bodies and provides information about the observed extent of inundation for waterways and floodplains. It is a resource for both users and providers of information about surface water permanence and the extent and frequency of inundation. Potential users include government agencies, research institutions, the general public and academia.
