The multi‐objective land allocation problem is to optimize the selection of land for different uses based on a set of decision objectives. For most applications, a geographical information system (GIS) is either absent or loosely coupled through file exchange. In this article the evolutionary algorithm (EA), a heuristic solution method for optimization problems, is integrated with a raster GIS to form a spatial decision support system (SDSS) for multi‐objective conservation reserve design. The SDSS effectively combines the functions of a GIS for data management, analysis, and visualization, with the optimization capability of the EA; and provides a uniform way to solve conservation reserve design problems with different types of constraints and objectives. The SDSS is demonstrated through application to the creation of conservation reserves in Bolivia to protect 17 endemic mammals. 相似文献

Knowledge-based spatial decision support systems (KBSDSS) incorporate heuristic reasoning, and analytical and spatial modelling capabilities to support decision making in resource and environmental management. They are able to provide the assistance for both the structuring and formulation of the spatial problem, and the design and execution of a solution process by automatically integrating different types of models and data. This paper presents a KBSDSS development environment, which connects a GIS tool (ARC/INFO) with an expert system tool (CLIPS) and a hypertext diagramming tool (HARDY). ARC/INFO provides capabilities for spatial data handling. CLIPS is used to develop knowledge bases and heuristic reasoning. HARDY is used to represent spatial problems in terms of diagrams that can then be translated into a CLIPS knowledge base for evaluation. The development environment allows users to structure their problems and develop models for particular requirements and domains. 相似文献

GIS空间数据具有多源性的特征,为数据综合利用和数据共享带来不便,解决多格式数据源集成一直是近年来GIS应用系统开发中需要解决的重要问题。ARC/INFO软件是当前众多地理信息系统软件中功能最强、市场占有率最高的软件。E00格式作为一种空间数据转换的事实上的标准,对于自主版权的GIS软件MapStore来说,实现两者的数据转换具有重要意义。本文分析了MapStore与ARC/INFO空间数据模型的组织特征,在比较分析的基础上设计了转换方案,并就实现过程中的关键技术进行了论述。 相似文献

In order to check the premature siltation of the reservoirs, the Government of India has launched the schemes of soil conservation and integrated watershed management in the catchments of River Valley Projects (RVPs) and Flood Prone Rivers. However, due to lack of sufficient funds and manpower for surveys and soil and water conservation programmes, a priority approach for treatment of the watersheds was developed and followed for implementation of soil conservation and watershed management schemes in India. This paper deals with the prioritisation of watersheds using GIS approach in a part of Musi river catchment in RR district of Andhra Pradesh. The GIS software package, ARC/INFO version 5.0, was used to digitize, edit, display, analyse and plot the maps. It was concluded that by the creation of computerised data base for the maps, the composite map generation and calculation of area statistics are performed much faster and more accurately compared to the conventional method. 相似文献

AbstractOver the last three decades, the information revolution and technological advances have led to a paradigm shift in cartography. Recently, the major emphasis has been on 'democratization of cartography', where individuals can be empowered with electronic tools to analyse and visualize spatially referenced data (Morrison, 1994). But, an ordinary user can not effectively use the available GIS tools to visualize geographical data. Therefore, cartographers and/or GIS experts need to develop user-friendly map making systems to facilitate the democratization of cartography. A mapping system was designed using the advanced macro language (AML) and menus of ARC/INFO at the Curriculum for Evaluation and Management Centre (CEM) in Durham University to automate the mapping process (extending from spatial and non-spatial data extraction to the printing of a final map), so that any user can map pupils' locations of any school in the United Kingdom simply by entering some key information. The procedure followed to automate pupils' mapping is described in this paper. A similar programming approach can be helpful to automate mapping systems in a local network and on web. 相似文献

In the present study, ground water prospect zones in Dala-Renukoot area, in Sonebhadra district. Uttar Pradesh, India have been delineated, through integration of various thematic maps using ARC/INFO GIS. Thematic maps in respect of geology, geomorphology. slope, drainage, land-use/land cover, lineament and lineament intersection frequency were prepared on 1:50,000 scale using remote sensing and conventional methods. These maps were scanned and registered with reference to a basemap and are input as separate layers using ARC/INFO GIS. Each theme was assigned a weightage depending on its influence on the movement and storage of groundwater and each unit in every theme map is assigned a knowledge based ranking from 1 to 5 depending on its significance to groundwater occurrence. All the themes are overlaid, two at a time and the resultant composite coverage is classified into five groundwater prospect categories. This output map is correlated with the groundwater data collected in the field. 相似文献

Geo-limis - a decision support system for minimizing locust impact in republic of kazakhstan 总被引:1,自引:0,他引:1

Desert locusts (DL) are serious problem during April to August in the deserts and semi-deserts of Republic of Kazakhstan and
causing extensive crop damage. There is no institutional and functional mechanism to forecast the habitat of locusts and most
of the area remains unnoticed after laying eggs. The key to improve DL forecasting and control depends on the collection and
generation of historical database on locusts, weather and habitat from affected region. Looking at the problem, a Spatial
Decision Support Systems (DSS) has been developed on ARC/INFO GIS with ergonomic user interface for ingestion and subsequent
analysis of locust related information vis-à-vis bio-physical and climatic data acquired from various satellite sensors and
hydromet weather server respectively, to identify high frequency breeding areas well before the physiological development
is completed. Weather based analytical models for physiological development of DL has been dovetailed with the SDSS for facilitating
historic and present data analysis in relation to locust activity. This has augmented the surveying capability and better
forecasting. 相似文献
