The objective of this study was to determine if decreasing pixel size incre
ases overall accuracy with which forest species can be separated using sate
llite data. Classification accuracy achieved with Landsat Thematic Mapper (
(TM)) channels 2, 3, and 4 were compared with results from SPOT-XS. Referen
ce data prepared from enlarged prints of aerial photographs and field check
s included 19 cover types, nine of which were coniferous. Results with SPOT
-XS alone yielded an overall accuracy of 70.1 percent, and with Landsat (TM
) 57.1 percent at species level. Overall accuracy increased by 3 percent wh
en either SPOT-XS or Landsat (TM) data were integrated with SPOT-PAN data.
