Table 1.

Landscape units in the Balkhash basin and the associated field data. The names of the units are built up out of three letters, representing a high (capital letter) or low value (lower case letter) of TC-Brightness (B/b), TC-Greenness (G/g) or DEM-SD (D/d). RF denotes Random Forest.

Landscape unit	Location field data	Number of squares available for RF analysis	Number of burrows available for RF analysis	Stratified RF
bgd	East	6	124	RF bgd-East
Bgd	East and West	24	452	RF Bgd-West and RF Bgd East
bGd	East	16	172	RF bGd East
BGd	–	0*	0*	(Only unstratified RF)
BgD	East and West	6	141	RF BgD West and RF BgD East
bgD	–	0*	0*	(Only unstratified RF)
bGD	East	2	15*	(Only unstratified RF)
BGD	–	0*	0*	(Only unstratified RF)
Total	East and West	54	904

^*No research squares, or too few burrows are located in this landscape unit, so the RF built to classify this area is unstratified, i.e. based on all the squares in the respective SPOT scene.
