Landsat TM & SPOT 5 Foliage Projective Cover (FPC) Products

973 Words2 Pages

Foliage Projective Cover (FPC) is a measure of vegetation density represented by the percentage of ground covered by photosynthetic overstorey foliage (Scarth, Armston & Danaher 2008). As changes in FPC over time can indicate land clearing, the Statewide Landcover and Trees Study (SLATS) was initiated in Queensland to provide quantitative data to assess the related greenhouse gas emissions (Goulevitch, Danaher & Walls 1999). Originally SLATS used Landsat TM imagery to predict FPC across Queensland and New South Wales, but recently adopted SPOT 5 imagery (Flood et al. 2013; Kuhnell et al. 1998). SPOT and Landsat FPC Products have been found to differ for some land cover types (Phinn 2014).
The aims of this project are:
1. To compare Foliage Projective Cover (FPC) Time Series from Landsat TM and SPOT 5 HRG:
a. To identify the mean and variance of each FPC Time Series for specific land cover types based on vegetation communities; and
b. To compare the mean and variance of the Landsat TM and SPOT 5 HRG FPC Time Series for specific land cover types based on vegetation communities; and
c. To assess and explain the causes of the differences between the FPC Products.
Statement of the Problem
Remote sensing technology provides a cost-effective method to acquire biophysical information across the 2.5 million km2 area represented by the combined Queensland and New South Wales territories (Meier et al. 2011). SLATS commenced in 1995 to develop methods and technologies to provide environmental monitoring (Kuhnell et al. 1998). SLATS produce a Foliage Projective Cover (FPC) Product which is used to inform environment and climate change analysis and subsequent decision making (Huete 2012).
