An invasive weed has started to occur over large sections of the Wet Tropics and the state and local governments have set up a taskforce to control its spread. The weed of interest is pond-apple (Annona glabra) which occurs mainly in wetter areas in as a shrub up to 5m high, with a canopy that turns yellow in the drier months (Jun-August). One of the key pieces of information needed by the taskforce is an up to date map showing the location of weed patches that are at least 10,000m2 (100m x 100m, 1ha). The output map is to be presented in a format able to be used in existing GIS of the local and state government management agencies.
Describe how you would use remote sensing to address the task, be specific about the types of imagery (including spatial, spectral and temporal resolutions and characteristics), how imagery will be acquired and from whom, and when. Generally describe any ancillary data that would be useful and the type of analyses or procedures that should be performed to complete the task. Your recommendations should be based on trying to complete the task in an efficient and cost effective manner, but you may assume you are not subject to budget limitations.
