The classification procedure entails the use of IKONOS four by four meter imagery and Landsat TM thirty
by thirty meter imagery to classify wetlands, woodlands and the surface hydrology of the Scotty Creek
region. Upon completion of the initial IKONOS classification, the constructed data set facilitates the
bipartition of connected and disconnected wetlands with respect to the common drainage network.
Remotely sensed satellite imagery of the visible portion of the electromagnetic spectrum is commonly
used to facilitate the classification of wetland regions (Pietroniro et al, 1996). Satellite imagery
allows the construction of base maps from which data may be extracted of otherwise inaccessible regions.
Furthermore, other sources of data are often not available and thereby necessitate the acquisition of
remotely sensed imagery. A consequence of the use of satellite imagery is that the accuracy and
interpretation of these images are subjective and classification results may vary as a function of
operator skill. Further, distinct image properties, such as spectral and spatial resolution of the
surface features can hinder the classification process.
1. Ground surface classification and identification of wetlands and channel
fens within the Scotty Creek research watershed.
2. Classification of low resolution Landsat images for extrapolation and
analysis of the encompassing Liard River basin.
3. Classification of hydrological regions by the parameter of hydrological continuity and discontinuity.
