Conceptualizing smoothness and density as landscape elements in visual resource management
نویسنده
چکیده
Several dilemmas stand in the way of meeting the goals of visual resource management. The landscape is rich in potential qualities that can be assessed, but the choice of appropriate attributes is more difficult. What is readily measured is not necessarily what is most useful to examine. Furthermore, what is readily discernible from eyelevel photographs may not be readily available as mapped information. Two attributes, smoothness and density, are the focus of the current study. Their choice is based on prior empirical efforts and their promise as qualities that could be translated to mapped (e.g. geographic information system; GIS) form. Though intuitively straightforward, definitions of these concepts in terms that are amenable to computer-based spatial format posed a variety of challenges. The present effort has developed working definitions of these attributes that make them storable in other contexts and by other researchers. Further, an initial exploration of the relationship of these attributes to different landcover types suggests that although each landcover type tends to have its own characteristic range, these attributes also permit meaningful distinctions within these categories.

LAGA: A Software for Landscape Allocation using Genetic Algorithm
In this paper, Landscape Allocation using Genetic Algorithm (LAGA), a spatial multi-objective land use optimization software is introduced. The software helps in searching for optimal land use when multiple objectives such as suitability, area, cohesion and edge density indices are simultaneously involved. LAGA is a flexible and easy to use genetic algorithm-based software for optimizing the sp...

متن کاملInvestigation of Rangeland Changes Based on Landscape Metrics Analysis (Case Study: Kezab Rangelands, Yazd Province, Iran)
Adverse changes in rangeland vegetation can be considered as one of the criteria for land degradation. Some of these changes can be evaluated through monitoring the spatial changes of landscape parameters. This study aimed to investigate the landscape changes in Kezab rangelands of Yazd province, central Iran. Landsat satellite images of 1990, 2002, and 2013, and landscape metrics including Tot...
