The physiological status of forest canopy foliage is influenced by a range of factors that affect leaf pigment content and function. Recently, several indices have been developed from remotely sensed data that attempt to provide robust estimates of leaf chlorophyll content. These indices have been developed from either hand-held spectroradiometer spectra or(More)
Leaf and crown damage and discoloration characteristics are important variables when defining the health of eucalypt tree species and have been used as key indicators of environmental quality. These indicators can vary significantly over a few hectares, especially in mixed-species forests, making field-based environmental surveillance of crown condition an(More)
Simulation of the land subdivision process is useful in many applied and research areas. Planners use such tools to understand potential impacts of planning regulations prior to their implementation. While the credibility of both land-use change and urban growth models would be enhanced by integrating capabilities to simulate land subdivision, such research(More)
There is an urgent need within the international remote sensing community to establish a metadata standard for field spectroscopy that ensures high quality, interoperable metadata sets that can be archived and shared efficiently within Earth observation data sharing systems. Careful examination of all stages of metadata collection and analysis can inform a(More)
Scientific efforts to observe the state of natural systems over time, allowing the prediction of future states, have led to a burgeoning interest for organised storage of spectral field data and associated metadata, seen as being key to the successful and efficient modeling of such systems. A centralised system for such data established for the Australian(More)
Field and laboratory spectroscopy is a common method applied by different remote sensing user communities for various purposes, ranging from calibration/validation experiments to material identification (Milton 2009; Haest, et al. 2013). In all cases a large number of spectra tend to be collected, yet the value and sharing of such collections is often(More)
The establishment of invasive weeds in wetland environments is a prominent threat in Australia with adverse impacts on native flora. Current management is hindered by the lack of information available on which to base and justify management interventions, in particular, mapping of weed distributions. Remote sensing is a possible solution to difficulties of(More)
