The Karst Feature Database (KFD) of Minnesota is a relational GIS-based Database Management System (DBMS). Previous karst feature datasets used inconsistent attributes to describe karst features in different areas of Minnesota. Existing metadata were modified and standardized to represent a comprehensive metadata for all the karst features in Minnesota. Microsoft Access 2000 and ArcView 3.2 were used to develop this working database. Existing county and sub-county karst feature datasets have been assembled into the KFD, which is capable of visualizing and analyzing the entire data set. By November 17 2002, 11,682 karst features were stored in the KFD of Minnesota. Data tables are stored in a Microsoft Access 2000 DBMS and linked to corresponding ArcView applications. The current KFD of Minnesota has been moved from a Windows NT server to a Windows 2000 Citrix server accessible to researchers and planners through networked interfaces. 相似文献

大千世界万物众生,具有物以类聚、人以群分的客观规律,因而促使对客观对象的科学研究皆可采用分门别类的方法去进行,这一理念同样可以延伸到地图制图及地理信息系统等以地物、地图为研究对象的学科中。由此衍生的数据分层是地理信息系统的关键词之一,科学有效的数据分层,是数据管理、GIS地图编制、制图综合、专题制图、空间分析的前提,国内、外著名的CAD、GIS软件都充分利用了层概念和其技术。在讨论层概念的基础上,利用两个在地学界应用比较广泛的和著名的GIS软件即我国具有自主版权的MapGIS和来自美国的ArcGIS,仔细研究和分析了层概念在软件中的应用;经研究进一步表明,数据分层是GIS技术得以进行空间数据管理、表达及进行空间分析的基础;在此基础上,对主题层、数据层、图层进行了概念上的界定,以此帮助对GIS技术的理解和应用。 相似文献

This paper discusses how GIS (Geographic Information System) can contribute to the research field of urban analysis. The purpose
of urban analysis is to explain the processes of spatial distributions in urban areas. For this purpose, urban analysts often
need to manipulate large amounts of spatial data. This is the reason why urban analysis cannot advance without GIS. Analysts
can visualize urban affairs using GIS and find the processes of spatial distributions. For example, in this paper, land use
distributions in Nagoya City, Japan are visually analyzed with ArcView GIS. This analysis demonstrates that GIS can contribute
to urban analysis. After this analysis, future work is discussed based on the reviews of recent studies on urban analysis
using GIS.

This paper presents a geographic information system (GIS)-based multicriteria decision-making approach for biodiversity preservation of the Ahaggar National Park in Algeria. This tool named spatial decision-making aid (SDMA) enables decision makers to evaluate the relative priorities of conserving the biodiversity in protected areas basing on a set of preferences, criteria and indicators of the area. In this study, we have developed conceptual and methodological solutions to integrate outranking methods (such as elimination and choice to translate reality TRI, preference ranking organizational methods and analytical hierarchy process) of multicriteria analysis in the GIS software to enhance its potential as tools of spatial decision support in land management problems. We integrated the results and other data relevant studied area in a GIS as a starting point for our SDMA prototype for resources management. Through the application, we have designed functionalities that allow producing maps of areas which needed urgent preservation. These methods are more appropriate to decision-making problems and their integration into GIS software (ArcView GIS 3.2 software from Environmental Systems Research Institute) that constitutes a powerful tool of spatial decision-making aid. 相似文献

Prediction of Floor Water Inrush: The Application of GIS-Based AHP Vulnerable Index Method to Donghuantuo Coal Mine,China 总被引：6，自引：0，他引：6

Floor water inrush represents a geohazard that can pose significant threat to safe operations for instance in coal mines in
China and elsewhere. Its occurrence is controlled by many factors, and the processes are often not amenable to mathematical
expressions. To evaluate the water inrush risk, the paper proposes the vulnerability index approach by coupling the analytic
hierarchy process (AHP) and geographic information system (GIS). The detailed procedures of using this innovative approach
are shown in a case study in China (Donghuantuo Coal Mine). The powerful spatial data analysis functions of GIS was used to
establish the thematic layer of each of the six factors that control the water inrush, and the contribution weights of each
factor was determined with the AHP method. The established AHP evaluation model was used to determine the threshold value
for each risk level with a histogram of the water inrush vulnerability index. As a result, the mine area was divided into
five regions with different vulnerability levels which served as general guidelines for the mine operations. The prediction
results were further corroborated with the actual mining data, and the evaluation result is satisfactory. 相似文献

Although the research and application of a geographic information system (GIS) in bibliometrics remains in its initial stage, several valuable attempts have been made in recent years. This paper provides our overview regarding this area. We first reviewed the spatial information mining derived from literature, including structured and unstructured data. The spatial display and the basic spatial operations for the geographic information derived from literature were then introduced, demonstrating that GIS can be directly used to construct digital libraries. Some literature database websites have begun to utilize WEBGIS to display the spatial distribution of an author’s location. Additionally, the spatial distribution information can be displayed in various modes with other specialized tools. Potential spatial analyses in bibliometrics were then discussed, introducing geostatistical and buffer analyses as case studies. Finally, several bibliometric indicators attached with research units were investigated. When the quantitative research index units are linked with the research spatial position, they can be displayed, queried and retrieved spatially. Future work to advance the application and research of GIS in bibliometrics is still warranted. 相似文献

Groundwater inrush is a geohazard that can significantly impact safe operations of the coal mines in China. Its occurrence
is controlled by many factors and processes are often not amenable to mathematical expressions. To evaluate the water inrush
risk, Professor Wu and his colleagues have proposed the vulnerability index approach by coupling the artificial neural network
(ANN) and geographic information system (GIS). The detailed procedures of using this innovative approach are shown in a case
study. Firstly, the powerful spatial data analysis functions of GIS was used to establish the thematic layer of each of the
main factors that control the water inrush, and then to choose the training sample on the thematic layer with the ANN-BP Arithmetic.
Secondly, the ANN evaluation model of the water inrush was established to determine the threshold value for each risk level
with a histogram of the water inrush vulnerability index. As a result, the mine area was divided into four regions with different
vulnerability levels and they served as the general guidelines for the mine operations. 相似文献

Accounting for spatial patterns of multiple geological data sets in geological thematic mapping using GIS-based spatial analysis 总被引：2，自引：0，他引：2
This paper presents a Geographic Information System (GIS)-based spatial analysis scheme to account for spatial patterns and
association in geological thematic mapping with multiple geological data sets. The multi-buffer zone analysis, the main part
of the present study, was addressed to reveal the spatial pattern around geological source primitives and statistical analysis
based on a contingency table was performed to extract information for the assessment of an integrated layer. Mineral potential
mapping using multiple geological data sets from Ogdong in Korea was carried out to illustrate application of this methodology.
The results obtained from the case study indicated that some geochemical elements and residual magnetic anomaly dominantly
affected spatial patterns of the mineral potential map in the study area and the dominant classes of input data layers were
also extracted. This information on spatial patterns of multiple geological data sets around mines could be used as effective
evidences for the interpretation of the integrated layer within GIS. 相似文献
