— This paper reports on the use of computer and hand dravm techniques for Implementing the Recreation Oppor­ tunity Planning inventory and analysis phases for the Steens Mountain Recreation Lands. Techniques were compared for land classifications and time and monetary costs. Results show computer mapping less likely to result in classification er­ rors, but more costly to conduct. The USDI Bure...

Terrain attributes are commonly used to explain the spatial variability of agronomic, pedologic, and hydrologic variables. The terrain attributes studied here (elevation, slope, aspect, and curvature) are estimated readily from digital elevation models (DEMs), but questions remain about how the accuracy and sample spacing of the elevation data affect the estimated attributes. The main objective...

Many land-management agencies are caught between decreased budgets and increasing public interest. Furthermore, semi-arid landscapes are sensitive to management prescriptions and use, and require a significant amount of monitoring in order to assess vegetation productivity and health. The purpose of this study was to evaluate the use of Landsat Enhanced Thematic Mapper (ETM) Imagery to monitor ...

Loess shoulder-lines are significant structural lines which divide the complicated loess landform into loess interfluves and gully-slope lands. Existing extraction algorithms for shoulder-lines mainly are based on local maximum of terrain features. These algorithms are sensitive to noise for complicated loess surface and the extraction parameters are difficult to be determined, making the extra...

The criteria for planting maize should be consistent with sensible and ecological to determine the potential lands. However, there is still a lack of proven methodology this evaluation. purpose analysis was parameters that affect multi-criteria decision maize, aim new method on land suitability analysis. proposed based GIS-analysis management such as distance from roads, rivers, slope, LULC, el...

The paper deals with morphological properties of agrogenically transformed chestnut soils slope lands in the south Volga upland within urban landscape Volgograd. It is established that as a result agrogenesis, erosion, land use change, well agroforestry reclamation measures performed, both anthropogenic deeply and postagrogenic have been formed. greatest changes under influence agrogenesis are ...
