peri-urban area development process decreases agricultural land use because of significant trend of city sprawl. in the agricultural sector, goals for sustainability generally include maintenance or enhancement of the natural environment, meeting of human needs for food, economic viability, and social welfare. as agriculture has enormous environmental impacts on peri-urban regions, it is necess...

Geographical information system (GIS) is a powerful tool in managing and presenting spatial referenced data science it has a lot of geographic functions such as data integration, mapping, overlaying, buffering, projection....etc, but on the contrary it is a limited tool in decision aiding of spatial decision problems. It can't stand alone in taking decision in spatial problem environment. In th...

abstract in current world environmental and mainly urban wastes are originated mostly from massive human habitat areas, and have caused disturbance, uncomfortable landscape, environmental risks and dissatisfaction. saqqez city with a population of 140000 is one of the largest cities in kurdistan province. due to population increase, consumptions and changes in nutritional habits of people, the ...

Spatial Decision Support Systems (SDSS) assist decision makers in analyzing spatial problems and evaluate alternative solutions using applicable spatial and non-spatial data as well as analytical models. SDSS environments are typically built on top of Geographical Information Systems (GIS), which are capable of storing, manipulating and displaying geographically referenced information. Traditio...

A Watershed Management Decision Support System (WAMADSS) is used to evaluate the economic and environmental consequences of alternative land use/management practices (LUMPs). WAMADSS consists of three components: (1) a GIS, (2) an economic model, and (3) two environmental simulation models. Specifically, ARC/INFO serves as the engine for integrating the Cost and Return Estimator (CARE) program,...

The design and implementation of software for extracting information from GIS files to a format appropriate for use in a spatial modeling software environment is described. This has resulted in publicly available c/c++ language programs for extracting polygons as well as database information from ArcView shape files into the Matlab software environment. In addition, a set of publicly available ...

This paper describes a link between a Geographical Information System (GIS), ARC/INFO TM , and an interactive dynamic graphics program, XGobi. GISs provide a user with a standard and convenient software for spatial geographical data. In particular, the GIS ARC/INFO is a combination of two systems: ARC maintains the spatial information of map features and provides tools for spatial analyses whil...
