A review on application of geographical information system in town planning in Malaysia

A review on application of geographical information system in town planning in Malaysia

To resolve these problems, GIS applications have been developed such as Development Control System, DBKL, City Development Management System, Putrajaya and Safe City Monitoring System. Thus, the application development consists of monitoring or planning categories. Therefore, the features of applications developed to support the application have data elements such as base maps, planning and development, services and facilities, utilities and economic resources. The results showed that GIS is used to solve problems involving town planning. Other than to facilitate the process of updating and assessing information, this system can save cost and time in which there is no repetition of the process data. The use of GIS system allows the public to submit applications through the website. In addition, GIS application provides the database to control large data. GIS applications also help to monitor the effectiveness of the Safe City program to tackle crime. Therefore, GIS applications have been developed to identify the existing and potential hotspots, crime patterns and the frequent crime locations. The analysis done in GIS application is the preparation of spatial-formed statistics and reports, searching of map digital information and management of geographic information.

Role of Geographical Information System (Gis) in Determining Locations

Role of Geographical Information System (Gis) in Determining Locations

and more intense using these advanced solutions can turn into a real competitive advantage. Thus Retailers can benefit from GIS and maybe in the future can think of building a national database with data that all economic agents can access, as in case of USA. Thus GIS can bring in Significant improvements in boosting their sales , reducing costs and wastes ensuring faster decisions to the retail and marketing managers. GIS as a tool or technology actually exists but somewhere in the analytics of the GIS process it is encountered that there is a gap in the availability of resources and interpretation from the resources in retail GIS analysis and discovery process. This is could be due to lack of skill in using and handling data. In addition, the researchers have differing levels of computer skills and relied heavily on "institutional" knowledge acquired over the course of years but we have noted that something over and above software education and understanding is required to handle GIS and expertise in this technology, as use of this is specific to situation, location and needs per say.

category at the day of application. The infor- mation of the locations of the farms with ani- mal production as well as their production type and herd sizes are collected from these two reg- istries. The disease recording system of the Na- tional Veterinary Institute includes the results from all tests of samples tested according to surveillance programs as well as diagnostic purposes of disease investigation. Today, all in- formation about disease status in the counties, municipalities or on each farm can be collected from this database and imported into ArcView 3.1 as text files for joining with a geo-refer- enced theme such as farm, municipality, veteri- nary district or region. The GIS can thereby show the summarised information at a specific time or over any desired time period. Alterna- tively, the information in the database can be accessed through the ODBC interface. A goal of the introduction of GIS is to have maps continuously displaying the situation for each of the diseases included in the Norwegian Surveillance Program.

Highway Alignment Using Geographical Information System

Highway Alignment Using Geographical Information System

The vector model, the spatial locations of features is defined on the basis of coordinate pairs. These can be discrete, taking the form of points linked together to form discrete sections of line; linked together to form closed boundaries encompassing an area Attribute data pertaining the individual spatial features is maintained in an external database. In dealing with vector data any important concept is that Topology. Topology derived from geometrical mathematics, is concerned with order, contiguity and relative position rather than with actual linear dimensions. Topology is useful in GIS because many spatial modeling operations do not require coordinate locations, only topological information-for example to find an optimal path between two points requires a list of the arcs or lines that connect to each other and the cost to transverse them in each direction. It is also possible to perform the same spatial modelling and interrogation processes without using stored topology, by processing the geometrical data directly by generating topology on the fly or using vector object model as and when it is required.

Mapping of Power Distribution Network using Geographical Information System (GIS)

Geographical Information System in management of power distribution system. Traditional management system is not only manual but also has flaws such as difficulties in searching previous records and updating them, which is very time consuming task. Using GIS, Roads and buildings of UET Lahore have been mapped. Another layer of HT/LT network of UET Lahore overlaid on it. Databases have been created for poles, HT/LT lines and transformers, which stores the required information for decision making, future planning and analysis such as locations of dangerous/deteriorated poles, load on a particular transformer or location of loose jumpers of HT/LT lines. Mapping the electricity network in GIS can help us plan for preventive maintenance, easy retrieval of records, avoiding site surveys for new connections and improved material management. The integration of spatial database with analytical tools will be allowing the system to be planned more economically resulting in more efficient power distribution systems.

IDENTIFICATION OF ROAD CRASH BLACK-SITES USING GEOGRAPHICAL INFORMATION SYSTEM

IDENTIFICATION OF ROAD CRASH BLACK-SITES USING GEOGRAPHICAL INFORMATION SYSTEM

Abstract: It is a crucial task to reduce road crashes by performing analyses and taking appropriate countermeasures to save lives. It has been a major issue for many people and government to reduce the amount of road collisions especially in Iran, since it could be a great threat to this country. Identification of crash black-sites is one of the most important fields in road safety studies. Many highway agencies have been using Geographical Information System (GIS) for analyzing crash data. The GIS based application integrates the information collection capabilities with the visualization. In this paper, Incident features like location, date, type of vehicle involved, and number of persons injured or died are imported in the GIS database. Then, Kernel density is to apply on the prepared data. The main objective is to specify road crash black-spots considering all types of traffic crashes based on their severity using Kernel Density through GIS environment. The results show that more severe crashes take place further from the cities than accidents with only property damages. Also, overlaying all crash types using the suggested SI (severity index) method will generate crash black-sites map which policy makers can use to determine accident-prone zones and take appropriate interventions. Keywords: GIS, accident-prone zones, severity index, kernel density, road safety.

Geographical Information System Based Safe Path Recommender

Geographical Information System Based Safe Path Recommender

The system is a dynamic web-application in which the user can find the safest path as well as report crime in any locality of Delhi.The various regions of the city as available in the dataset, are clustered using k-means algorithm on the basis of the crime rate. This crime rate is calculated by giving more weightage to some particular crimes against women. Accordingly, clusters are formed containing locations of similar type.Each cluster is assigned with a crime index ranging from 0 to 4. It is calculated, for each custer, by giving special weightage to the features – rape, sexual harassment and gang-rape. For each cluster of locations, the mean of these features is summed up and then resultant sums are sorted in increasing order. The cluster with minimum sum gets minimum crime index 0 and consequently the one with maximum sum gets maximum crime index 5. The localities along with their final crime index are stored in the database.Coming to the user- interface, the homepage of the website displays a message if the user wants to report any crime can press the globe icon at the top.If yes, the user is asked to select the locality and type of crime and report the crime by submitting the data, which is used to calculate new crime indices. Otherwise, user is asked to enter source and destination. Google maps fetches all possible routes from source to destination. The danger index of each path is calculated by taking the mean of the crime indices of all the locations in that path. Three routes with the least danger indices are displayed to the user.

Building and Applying Geographical Information System Grids

Building and Applying Geographical Information System Grids

For each event magnitude we make four different measurements. Although there are few other steps involved in the process such as initialization of the Java objects and extraction of the database query from the user request, they do not take significant amount of time and are not determinative in the total response time. Database query time displayed in column 2 is the major contributor to the total response time and demonstrates a similar value for all the data sizes. Building GML objects from database query results was another major time consuming process in our previous tests [17] especially for larger GML payloads however with the new improvements this process only takes about 10% at most and can be ignored for the larger event magnitudes. “Total Request Processing Time” column shows the total amount of time spent on the server side for processing a user request. From the client’s point of view the performance of the WFS is simply the amount of time between submission of the request and the retrieval of the result. For this reason we also measure the data transport time. However the actual transport time will greatly depend on the quality of the network connection between the client and the WFS server, and the transport timings we give her are only sample results for our test set up.

Title: The Hydro-Ecological Process in Spatial Database Management System

Title: The Hydro-Ecological Process in Spatial Database Management System

It is evident that landform is the dominant factor control- ling the pattern of a stream network, though it is not the only single factor. Hence GIS techniques are usually employed to analyse and assess topography-dependent hydro-geomorphic information and other hydrological information closely cor- related with landforms (Forman, 1995). The development of a DEM is also a useful substitute for the traditional field work which requires for a tough work on such information collection, and it allows an easier availability of digital hydro- logical information for hydro- ecologicalresearch work. Most hydrological software such as Rivertools, TOPAZ (TOpographic PArameteriZation) and ArcGIS have had their specific hydro- logical analysis modules, with which some key hydrological indicators such as stream network, watershed line and sub- catchment delineation can be digitally generated from a DEM (Turcotte et al., 2001). With the aid of field monitoring, more hydrological indicators of the hydro-geomorphology or the

Information management at state highway departments: Issues and needs

Information management at state highway departments: Issues and needs

The current NCDOT crash reporting data system (CRS) resides on an IBM ES9000 computer at State Information Processing Services, an entirely separate State Department. Monthly reports are generated that provide users with hard copies of the information they require for analysis. The data contained in these reports is often found to be in error and corrections do not necessarily make their way back to the CRS. The process for making changes to the System and recreating previously extracted files is both difficult and time-consuming. Because of this, users often rely on extracted data that may have become out-of-date, which leads to different user groups relying on different versions of the same data.
