Vegetation height and structure - derived from ALOS-1 PALSAR, Landsat and ICESat/GLAS, Australia coverage

Vertical plant profiles for the Australian continent were derived through integration of ICESat GLAS waveforms with ALOS PALSAR and Landsat data products. Co-registered Landsat Foliage Projected Cover (FPC) and ALOS PALSAR L-band HH and HV mosaics were segmented to generate objects with similar radar backscatter and cover characteristics. Within these, height, cover, age class and L-band backscatter characteristics were summarised based on the ICESat and Landsat time-series and ALOS PALSAR datasets.

Filenames for these products conforms to the AusCover standard naming convention. The standard form of this convention is: <satellite category code><instrument code><product code>_<where>_<when>_<processing stage code>_<additional dataset specific tags> HEIGHT TIF PRODUCTS (percentile heights are the height where that percentage of plant material has been intercepted within a cluster, where a cluster is a group of similar segments) alpsbk_aust_y2009_sd1a2.tif - Height where 25% of the plant cover has been intercepted (DN=decimetres+1; unsigned 16 bit; null=0) alpsbk_aust_y2009_sd2a2.tif - Height where 50% of the plant cover has been intercepted (DN=decimetres+1; unsigned 16 bit; null=0) alpsbk_aust_y2009_sd3a2.tif - Height where 75% of the plant cover has been intercepted (DN=decimetres+1; unsigned 16 bit; null=0) alpsbk_aust_y2009_sd4a2.tif - Height where 95% of the plant cover has been intercepted (DN=decimetres+1; unsigned 16 bit; null=0) alpsbk_aust_y2009_sd5a2.tif - Height of peak plant cover density (DN=decimetres+1; unsigned 16 bit; null=0) PLANT COVER TIF PRODUCTS (Defined as 1 - gap fraction) alpsbk_aust_y2009_se1a2.tif - Fraction of plant cover below 5m (DN=percentage*100+1; unsigned 16 bit; null=0) alpsbk_aust_y2009_se2a2.tif - Fraction of plant cover between 5m and 10m (DN=percentage*100+1; unsigned 16 bit; null=0) alpsbk_aust_y2009_se3a2.tif - Fraction of plant cover between 10m and 30m (DN=percentage*100+1; unsigned 16 bit; null=0) alpsbk_aust_y2009_se4a2.tif - Fraction of plant cover above 30m (DN=percentage*100+1; unsigned 16 bit; null=0) alpsbk_aust_y2009_se5a2.tif - Total plant cover fraction (DN=percentage*100+1; unsigned 16 bit; null=0) STRUCTURE TIF PRODUCT (Categorical data) alpsbk_aust_y2009_sf1a2.tif - Forest structure codes derived from alpsbk_aust_y2009_sd4a2.tif and alpsbk_aust_y2009_se5a2.tif using a version of the Walker and Hopkins (1990) structural classification Code Structural Formation Total plant cover fraction 95th Percentile Height 0 No Data - - 10 No trees 0% - 21 Low scattered trees 0% to 6% <9m 22 Medium scattered trees 0% to 6% 9m to 17m 31 Low open woodland 6% to 11% <9m 32 Medium open woodland 6% to 11% 9m to 17m 33 Tall open woodland 6% to 11% 17m to 27m 41 Low woodland 11% to 30% <9m 42 Medium woodland 11% to 30% 9m to 17m 43 Tall woodland 11% to 30% 17m to 27m 44 Very tall woodland 11% to 30% 27m to 57m 51 Low open forest 30% to 70% <9m 52 Medium open forest 30% to 70% 9m to 17m 53 Tall open forest 30% to 70% 17m to 27m 54 Very tall open forest 30% to 70% 27m to 57m 55 Extremely tall open forest 30% to 70% >57m 63 Tall closed forest >70% 17m to 27m 64 Very tall closed forest >70% 27m to 57m

Statement
Horizontal Positional Accuracy The data described here has been registered to a USGS provided L1T ETM panchromatic baseline. It is not recommended that these data sets be used at scales more detailed than 1:100,000. Vertical Positional Accuracy The accuracy of the height estimates increases as the canopy density increases. A full accuracy assessment is ongoing, but indicative plots of the height accuracy as compared to airborne lidar over TERN-AusCover supersites is illustrated in the figure not provided.
