Abstract: The paper addresses elements of a cost-estimating approach for photogrammetric mapping and related aerial photography and control surveying services. The background for the estimating approach is presented, as are the ...

Abstract: Rising Lake Michigan water levels were found to negatively influence the amount of wetlands and beaches in the Straits of Mackinac area of Lake Michigan. The effects of long‐term fluctuation in water levels were determined ...

Abstract: To halt erosion and desertification, it is necessary to quantify resources that are affected. Necessary information includes inventory of croplands and desert areas as they change over time. Several studies indicate the ...

Abstract: High-resolution aircraft or satellite data often require ground or image control for rectification of images, and this is best performed using control with a similar level of spatial resolution. To demonstrate the use of ...

Abstract: Two different models were used to simulate the influence of commercial vessels transiting narrow‐cross‐sectional channels in the presence and absence of ice. Models were developed by two contracted groups using hydraulic ...

Abstract: In soils developed in loess over glacial till, the presence and depth to clay layers, or fragipans, and other features are identified with radar. Radar evaluation of depths to soil features compares well with the soil pit ...

Abstract: Three models are presented that use the presence and spatial characteristics of land‐cover types to calculate quality of wildlife habitat. The modeling approaches include the use of a Geographic Information System (GIS) ...
