The aim of this paper is to reveal the potential of Free and Open Source Software for GIS (FOSS4GIS) in Space Syntax (SS) analysis. For this purpose, firstly the existing software exclusively developed for SS are reviewed in order to unveil both their modalities to produce the key measures of SS and illustrate the lack of their cooperation with GIS and Social Network Analysis (SNA) software. After...
At present, application of GIS is in a process of transition from macro space to micro space, such as indoor space, a kind of micro environment that has a smaller scale than outdoor space. There have been some applications for indoor space, covering issues like path finding, emergency planning, object tracking, etc. Behind these applications, indoor spatial models are needed to illustrate how built...
SharpMap is one of the Open Source GIS Projects. It is an easy to use mapping library for use in web and desktop applications. Because the commercial GIS software has a large scale and costs are too high, so the range of applications is limited in small-scale secondary development. While the SharpMap is a small, open source, good map rendering library. It is very suitable for small-scale Software...
Because of low processing speed of CPU and small memory space, time efficiency of portable hardware, where Mobile GIS is running, is low when processing the mass data. A variety of plans, which can improve the time efficiency of rendering the mass data by application software at user side of Mobile GIS, were studied in terms of development language selection, rendering process control, memory mapping,...
In land planning, data conversion between CAD and GIS becomes the data-sharing a great challenge. In this paper, three aspects were studied. First of all, the organization style between CAD and GIS data are compared. Secondly, the data conversion method based on FME is proposed, and, we analyze its semantic transformation model system. Finally, the coordinate transformation which takes place before...
Geographic Information System (GIS) not only has the function of managing geographic information and processing graphics, but also can resolve the problems of complex spatial analysis, spatial simulation and spatial decision-making. Geographic fractal research, whether measuring fractal dimension or simulating fractal structure, is a rule and complicated process. Some popular GIS software has many...
Hydrological features are always important information for water resources computing. 3D (three-dimensional) GIS (Geographic Information System) technique provides a feature extracting and 3D scene displaying platform for management and decision. In our case study, contrasting and analyzing current three system development patterns, we have presented the 3D development tool and system architecture...
The GIS college education system covers a wide range of knowledge. It requires high standards of technologies to support it. Colleges and their students have both been greatly challenged in the process of teaching and learning. The main purpose of the GIS college education is to bring up professional engineers who can meet the demands of the society. Through analyzing the GIS college educational system...
Currently, with many popular GIS software platforms occurring, interoperating data in different platforms has an important application value. Taking MIF data for an example, which is the Interchange Format of MapInfo, this article puts forward three ways of MIF data interoperability in ArcGIS platform through the analysis of data format of MIF, namely interoperated Quick Import tool for calling data,...
The features of mass spatial data and the limit of Internet bandwidth are key issues which restrict the WebGIS application performance. How to implement efficient vector data compression is important during the stage of data transmission. To get high compression ratio, we propose one multilevel vector data compression method which combine lossy compression and lossless compression technology. According...
In this paper, the application of GIS-based land suitability evaluation has been discussed, and then the key problems in the process have been analyzed, finally, we take Dujia village coal mine in ShanXi province, China as an example to exemplify the process of land suitability evaluation by GIS spatial analysis function.
GIS-based mapping and decision support system has been efficiently and widely used in many different fields and domains. In practice, however, the application in forestry is still relatively limited, especially the large-scale mapping and specialized software development, which has witnessed a growing market from various customers. Supported by National High Technology Research and Development Program...
The technology of Geographic Information System is applied widely in urban planning. In this paper we will discuss the application, development and exiting problems of geographic information system in urban planning. Through these studies, we hope geographic information system will serve for the urban planning better.
AnyLogic is a kind of excellent software of complex system simulation. It can more accurately reflect the information of real life and expand the application of complex system simulation by adding GIS map as agent's environment. But, there are some problems at present when importing GIS data to AnyLogic. Based on the analysis of differences between ordinary engineering drawing and GIS vector diagram,...
The ecological zone is the smallest unit perceived and relatively consistent in the ecological landscape, and it's also a group of symbiotic community geographically, reflecting the specific climate, soil, vegetation and ecological conditions. There're a number of unique top species, such as tropical rain forest, desert and other ecological domains in this unit. Owing to the continuous progress of...
With the aid of an integrated GIS/RS-based approach, authors chose the area within the second ring road of Kunming city, Yunnan province, PR China as study target on the basis of landscape ecology theory and method. Taking remote sensing images of 2000 and 2006 in Kunming city as data source and by means of a quantitative analysis method, the authors analyzed change of landscape pattern of Kunming...
Through the study of dramatic landscape pattern changes in the coastal zone of Nantong, China in 2003, 2005 and 2008, the influence of urbanization on natural landscape were reproduced using ARC/INFO software. Firstly we divided the remote sensing data into six categories, and then calculated varieties of landscape pattern indices according to Fragtats 3.3 software, we also counted spatial landscape...
Based on land use and urban plan maps, we extraced urban land information of Chongqing urban area in periods of 1995,2000.2008. With the help of GIS softwares and statistical analysis model, such indexes as expansion speed, expansion intensity, expansion direction, expansion morphological, and landscape features were used. This paper analyzed the spatio-temporal characteristics of urban land expansion...
This paper analyzed domestic existing fire simulation training system based on explaining fire hazard. In terms of some problems existing in the current system, and combining fire fighting troops' actual need of the work, GIS-based fire-fighting rescue simulation training system was designed and implemented. This paper expounded the system framework and functional features, and gave the way to achieve...
