NSW water count and water prevalence derived from Landsat data with 30 m pixels.
Data type:	Raster
Pixel size:	30 m
Base imagery:	Landsat 5 TM, Landsat 7 ETM+ (1988-2012)

Image pixel values

Water count (dd7):	
Band 1 - 001 to ~600 (number of times water was present)
Band 2 - 001 to ~600 (number of unobscured observations of the pixel)

Water prevalence (image ddh):
class 1 = 0%
class 2 = 0% to <10%
class 3 = 10% to <20%
class 4 = 20% to <30%
class 5 = 30% to <40%
class 6 = 40% to <50%
class 7 = 50% to <60%
class 8 = 60% to <70%
class 9 = 70% to <80%
class 10 = 80% to <90%
class 11 = 90% to <100%
class 12 = 100% (persistant water)
0 = null

The standard form of the file naming convention is:

<satellite category code>
<instrument code>
<product code>
_<where>
_<when>
_<processing stage code>
_<additional dataset specific tags>

For these datasets the naming is shown below (bar-separated):

Data Naming Element | Possible Code(s) | Descriptor Standard Elements
satellite category | lz | Landsat
instrument | tm | thematic
product | re | reflective
where | pathrow | reference system two path/row identifier, for example, p096r082
when  | yYYYYYYY  | start and end year
processing stage | dd7, ddh | Water count, water prevalence respectively
data projection | m4,m5,m6 | Universal Transverse Mercator (UTM) Zone 54, UTM Zone 55, UTM Zone 56
