    Description: This dissertation is concerned with the integration of satellite remote sensing and geographic information systems for the purpose of monitoring Great Lakes water quality. "Water quality" is defined as the physical, chemical and biological conditions that determine a water body's optical properties (i.e., its transparency and color). The utility of three operational satellite remote sensing systems, namely, the Landsat Thematic Mapper (TM), the SPOT High Resolution Visible (HRV) sensors and the NOAA Advanced Very High Resolution Radiometer (AVHRR), were evaluated as a means of estimating water quality and surface temperature. No one system was optimal for all water quality monitoring needs but the geographic information system (GIS) concept--a computerized data base of spatially registered information layers--provides a logical way of integrating the data from these various remote sensing systems. Empirical calibration through linear regression techniques was used to relate near-simultaneously...

    Description: Remotely sensed ice breakup dates for 62 lakes on the Laurentian Shield were analyzed to preliminarily assess determinants of the mean breakup date and to identify determinants of temporal coherence of lake‐ice breakup. Correlations between mean breakup date and the explanatory variables (surface area, maximum depth, surface area: maximum depth ratio, latitude, longitude, and elevation) revealed that only latitude ( = 0.96) and surface area ( 0.45) were significant at ≤ 0.05. Latitude and surface area were significantly correlated ( 0.42). The temporal coherence of breakup dates between each pair of lakes was calculated by taking the product‐moment correlation between their 8‐yr time series (1987–1994) of breakup dates. There is a general lack of strong temporal coherence between lakes, implying that no lake in this study area is representative of the entire region. The significant ( ≤ 0.05) correlates of the temporal coherence of breakup dates were difference in mean breakup date (‒0.49) and difference in latitude ( ‒0.51), themselves significantly correlated ( = 0.89). The differences in surface area, maximum depth, surface area: maximum depth ratio, longitude, and elevation were not significant. The general lack of strong temporal coherence between lakes and the significant correlation between coherence and mean breakup date are further confirmation that breakup dates for different lakes may be reflections of (and indicators for) different periods of meteorological forcing.

    Titre: Mapping lake water clarity with Landsat images in Wisconsin, U.S.A
    Auteur: Chipman, Jonathan W; Lillesand, Thomas M; Schmaltz, Jeffrey E; Leale, Jill E; Nordheim, Mark J
    Sujet: Geography
    Description: Landsat thematic mapper (TM) and enhanced thematic mapper plus (ETM+) images are being used to map lake water clarity region-wide in the Upper Midwest states of Minnesota, Wisconsin, and Michigan using a standardized image processing protocol. In Wisconsin, lake clarity estimates have been produced for 8645 lakes in the 1999-2001 time period. In addition to satellite imagery, the protocol relies on Secchi disk data collected by a network of citizen volunteers for development and validation of models. The most significant term in the regression model relating the satellite imagery to the field data is the ratio of spectral radiance values in the blue and red bands (ratio of Landsat band 1 to Landsat band 3). The resulting database of satellite-derived lake water clarity estimates represents an important new resource for lake managers in the region, and for those studying the linkages between lakes and their surrounding landscapes.

    Description: The overall goal of this study was to better understand the drivers of the expansion of agriculture in rural Senegal, and was attained through research focusing on two major objectives. (1) To determine an accurate approach for modeling the expansion of agriculture in southern Senegal. This objective required the comparison of multiple runs of the artificial neural network based Land Transformation Model, using a variety of parameterizations. Model modifications were made that maximized temporal generalization through the incorporation of land use/land cover change trajectories. (2) To explore the factors that are driving the expansion of agriculture in southern Senegal. Addressing this objective involved both modeling and detailed field investigations. A theoretical framework that emphasizes “extensification vs. intensification” of agriculture along the lines of the neo-Boserup-Malthus contradiction was used for assessing findings resulting from these investigations. Results of the study...

    Description: Synthetic aperture radar (SAR) interferometry represents a new method for topographic mapping. Experimental L-band (24 cm wavelength) interferometric SAR images from the second Shuttle Imaging Radar-C (SIR-C) mission in October 1994 were used to produce a digital elevation model (DEM) covering 2100 km 2 in northwestern Wisconsin. In non-forested areas this DEM has an accuracy of 3.5 m RMSE. In forested areas, there is a bias in the interferometric elevation estimates, such that the interferometric phase centers appear to be above (or in some cases, below) the ground surface. These biases are dependent upon forest type and structural characteristics. Models were derived to predict the interferometric elevation biases in red pine plantations based on mean stem diameter, for thinned and non-thinned stands (R2 of 0.88 and 0.72 respectively). In addition, the relationship between interferometric elevation biases and image-based characteristics such as SAR image backscatter magnitude, image texture,...
