Nowadays, with the development of navigation and location, many kinds of outdoor locating methods are surveyed and used, such as Global Position System (GPS) and LTE fingerprint-based positioning system. However, as the most compelling focus, the localization accuracies of these systems are limited by the location systems themselves. Therefore, in order to improve the localization accuracy, we should...
Agricultural land is the basis and guarantee for the survival and development of human. How to take scientific and effective use of agricultural land is an urgent problem to be solved. The suitability assessment can provide a good answer to this question. In order to realize the scientific, reasonable and efficient use of agricultural land under the lack of information condition, we carry out research...
In this paper we describe a bottom-up approach to integrate GIS maps (endorsed by discrete features, such as points, lines, polygons), in order to develop a route planner for wheelchair users. We integrate public available data with a novel model for route planning, based on sidewalks, crosswalks and curb ramps, as opposed to traditional street-based approaches. We show that our sidewalk-based model...
Passability maps are one of the basic elements used in military terrain assessment. The article describes an automating of their development. It performs all the stages of cartographic modelling, from data preparation to visualisation of the resulting passability maps in the form of a geoportal. A Vector Map Level 2 (VMap L2) was used as source data. In the described system, passability was relative...
Relief is one of the key components of the landscape. Therefore, its mapping and exploring has been done for centuries. Ways of examination the impact of the relief have been considerably extended by using geographic information systems. But until recently, it was difficult to study in detail the micro-relief components of relief. This was due to the fact that there were not sufficiently detailed...
Selecting the best route between the corridors and aligning between them is a intricate one due to the consideration of more number of variables. It is made through geology, topographical, geomorphology, built-up areas with environmental features representation on Remote Sensing (RS) and Geographical Information Systems (GIS). From this it is easy to recognize shortest path between the corridors for...
Best route location and highway alignment selection process is a complicated one due to many variables it must be considered. Geographic Information Systems (GIS) can easily represent such variables, including topography, environment, built-up areas and geology variables. It is to identify the short route for the vehicles travelling from Perundurai to Palani and to diminish the time journey for the...
The means of transportation development which are not offset by adequate roads construction will lead the traffic density exceeds the volume capacity of the roads. This will cause the access road difficult to pass thus often raises the risk of traffic congestion and lead to traffic accidents. This paper will discuss the use of Geographical Information System (GIS) technology in analyzing spatial data...
This case study focuses on the Digital Maritime Silk Road as referring to Chinese scholarly publications. The purpose is to allow museum visitors to experience the evolution of the concept of the Maritime Silk Road in China through the use of new technologies. Thus, an interactive visual and dynamic historical GIS (geographic information systems) approach has been created to be applied within a granularity...
Interacting with ridesharing systems is a complex spatiotemporal task. Traditional approaches rely on the full disclosure of a client's trip information to perform ride matching. However during poor service conditions of low supply or high demand, this requirement may mean that a client cannot find any ride matching their intentions. To address this within real-world road networks, we extend our map-based...
Electrical Supply Division (ESD) is responsible for the distribution of power supply safely and efficiently from the low voltage substation to consumer end points. However, with the growth in population density and the demand for energy the electric distribution system has become more complex and congested. It has become difficult for the linemen to locate the fault with the traditional method of...
Binary road images can be obtained from remotely sensed images with the aid of classification and segmentation techniques. Extracting road centrelines from these binary images are crucial to update a Geographic Information System (GIS) database. A current state of art method of centreline extraction needs to remove road junctions and depends on the accuracy of the endpoints, leading to three main...
Rice is still a major source of carbohydrates in the food consumption pattern in Indonesia. Availability of rice in Indonesia faces the challenges on the production side due to the production cycle following the water cycle while consumption remained relatively unchanged by time. This study aims to map the structure of production, consumption, and distribution in West Java and built a computational...
The Map Matching Problem (MMP) aims to find a real optimal region from a map repository, which is the most similar map to the ideal sample. Though there is a significant difference between MMP and the general Image Matching Problem. The former prefers approximate match and ignores details of edge. Both of them must solve variances of scale, translation and rotation. However, the Scale Invariant Feature...
Walking acts as an authentic link for intermodal transfer in major activity centers and helps to fulfil recreational and utilitarian trips in a city. To assess the condition and pattern of walking, walkability assessment is the primary option. In the last decade a large number of literatures in urban planning, public health and transportation have analyzed the role of the built environment on physical...
The urban road network shares self-similarity and is suitable to adopt the fractal theory for analysis. The fractal dimension of the urban road network reflects the completeness of the road system. The employment of fractal theory to analyze the urban road network can reflect the feasibility of the urban road network layout and is of vital significance to the evaluation of the urban road network planning...
Lines and Polygons Overlay Analysis (LP-OA) is an important analysis method that has been widely used in geographic information systems (GIS). In this study, a new algorithm, Uniform Spatial Grid Indexing (USGI), is proposed to study LP-OA. By applying this method, the theoretical position is evaluated and the theoretical results are verified, suggesting that this algorithm can contribute to the software...
This paper presents our recent research on augmented maps where unprepared paper maps are used and Geographic Information System serves both as reference database and augmentation data. We use road intersections to register paper map and GIS so several paper maps of the same city whatever their styles and colors can be augmented using the same reference database. We present a new road extraction method...
This paper presents the analysis of all driving by a single (female) older diver over a one year period from the Candrive project. Data analytics techniques have been applied to this unique big data set that includes 1 Hz sampled Global Positioning System (GPS) and Geographic Information System (GIS) data and includes the analysis of 1562 trips covering 13,425 km. The driver is known to have stable...
Flood is a major natural hazard occur recurrently in Sri Lanka. Allocating victims to camps and provide medical facilities are two main activities at the immediate response phase of a flood and use of manual methods delayed this process. This project developed a geo-enabled application to support immediate response planning, mainly focusing on allocation victims to IDP camps, provide medical facilities,...
