ABSTRACT 
An understand of the influence of topography on satellite data for geobotanic mapping allows 
geoscientists and others to develop strategies of precision for vegetation, lithological discrimination and 
responds to changes, mineral resource analysis and environmental hazard. In this paper an overview of 
12*12 pixel of the influence of topography on the analysis of Landsat thematic mapping satellite data of 
southeast of Quetico Provincial Park, Ontario, Canada for geobotanical mapping was investigated to 
establish correlations between tree species and density, the underlying rock, soil (geology) and 
topography. A topography information on subtle site was analyzed using a digital terrain model. 
Attempts on the elevation data were filtered to separate ridge tops from flat and other areas sites. All 
bands response characteristics were viewed for vegetation, geology and --- monitoring. An attempt to 
create a colour composite by combining bands 1 and 4; 3, 4 and 5; 4, 5 and 6 for producing an image 
map was not successful due to lack of facilities.
