| The purpose of this research is to compare the information content of two sensor's images with different resolutions and to establish techniques for quantifying and evaluating differences between these data sources. This thesis evaluated the effect of the differences between Thematic Mapper and Multispectral Scanner's spatial, spectral, and radiometric resolutions on the accuracy of landcover classification. A pair of satellite data, one Thematic Mapper and one Multispectral Scanner, taken on the same date, was used to test the robustness of unsupervised classification algorithms and normalized difference vegetation index images to capture the landcover characteristics. The results may be useful to those attempting to perform analysis with cross sensor data as is often done in archival studies involving change detection. |
