Abstract
This paper describes case studies using remote sensing and GIS to study, analyze, and interpret limnological data collected at the North Temperate Lakes (NTL) Long. Term Ecological Research (LTER) site. The NTL-LTER site is located in northern Wisconsin and represents one of 17 sites within the National Science Foundation sponsored LTER program. Many applications of remote sensing and GIS involve analyses of spatial data in the horizontal plane of the earth’s surface. This paper presents studies not only :in the horizontal plane but also in the vertical plane commonly found in vertical plane commonly found in limnological data as a of lake depth. Specific examples include: 1) landscape measures, 2) assessing lake spatial variability, 3) analyses of chemical and physical distributions along depth and time profiles, and 4) analyses of spatial patterns of biomass distribution along two dimensional depth and distance transects as recorded by sonar. Remote sensing and GIS have been found to be a useful tools not only for the management of spatial data collected as part of the LTER program but also for the analysis and interpretation of these data. Various remote sensing, image processing, and GIS tools have provided the opportunity to analyze limnological data in ways that have not been possible in the past. Remote sensing and GIS are helping limnologists to discover new insights into the structure and function of lakes at the NTL-LTER site.
