GIS as a tool for assessing the influence of countryside designations and planning policies on landscape change

Article Abstract:

Landscape change is influenced both by land use planning policies and countryside designations. The aerial photograph interpretation methodology and Geographic Information Systems (GIS) are used to assess both influences on specified landscapes. Landscape data is based on aerial photographs of 1968, 1981, and 1991, which serve as inputs for GIS analysis. GIS provides the spatial overlay analysis which helps in investigating the location, extent and rate of change in the landscape of designated areas. Areas which are not designated for conservation show poorer landscape features.

Application of GIS in training for environmental management

Article Abstract:

A course in Natural Resources Management uses geo-informatics in projects on eutrophication, acidification, ecological settlings, and Landsat-TM multispectral classification. Student cognizance is uneven and they face difficulty in linking different models and data, theory and problem solving, reducing the value of these time-consuming projects. Geo-informatics is developing dynamic modelling for the development of time series of maps and implementing Geographic Information Systems (GIS) to improve the student interface.

A GIS and TIR procedure to detect and map wall-base channels in Western Washington

Article Abstract:

The use of remote sensing methods to locate, detect and map wall-base channels are explored in western Washington. Digital elevation models and digital hydrography to create a geographic information system was initially applied to automatically locate the river floodplains and terraces that determine the creation and maintenance of wall-base channels in a river in Washington. The system was tested on the Clearwater River, Washington.
