Article
Full-text available
Complexity of urban construction and land use is increasing which cannot be represented adequately by 2D systems. The successful construction of a Spatial Information Model of 3D Real Estate (SIM-3RE) is valuable to achieving a refined administration of 3D space and property-rights of urban real estate in China. In this paper, the Nanjing Gulou Cen...

Accessibility research of healthcare facilities is developing towards multiple transportation modes (MTM), which are influenced by residential transportation choices and preferences. Due to differences in travel impact factors such as traffic conditions, origin location, distance to the destination, and economic cost, residents’ daily travel presen...

Background: Healthcare accessibility research is developing towards a focus on multimodal transport modes (MTM) and spatiotemporal variation. Dynamic traffic conditions lead residents to make distinct traveling decisions in different timepoints, which has an impact on the spatiotemporal accessibility of healthcare. Pediatric clinic services (PCS) a...

Real estate units are the elementary management units of uniform real estate registrations that include land and fixed objects such as aboveground buildings. Three-dimensional real estate objects better represent real estate units with complex structures and are suitable for ground-based, aerial and underground registrations of 3D real estate prope...

The spatial allocation rationality of the service facilities of residential areas, which is affected by the scope of the population and the capacity of service facilities, is meaningful for harmonious urban development. The growth of the internet, especially Internet map and location-based service (LBS) data, provides micro-scale knowledge about re...
Article
Topological relation is one of the basic topics of geographic information systems (GISs), and it has been widely applied in data organization and spatial analysis. It seems whether a simple topological relation can hardly represent complex space situations in some cases. Different topological relations may result in the same expression by some topo...

Full-text available
Topologies are crucial for the cadastral data model. Considering the development of three-dimensional (3D) cadaster and temporal cadaster, 0D-4D multidimensional cadastral objects should be considered in the cadastral data model. There are few data models to support 0D-4D multidimensional cadastral objects and their topological relations, and some...

Point-feature cartographic label placement (PFCLP) involves placing labels adjacent to their corresponding point features on a map. A widely accepted goal of PFCLP is to maximize the number of conflict-free labels. This paper presents an algorithm for PFCLP based on the four-slider (4S) model. The algorithm is composed of two phases: an initializat...

Full-text available
Extrusion is widely used to construct models in 3D cadasters. However, the basic extrusion approach only supports relatively simple conditions, and a 3D cadastral data model that supports extruded 3D models that are associated with their corresponding footprints is not available. In this paper, we present a new extrusion approach based on non-overl...

Full-text available
The labelling problem has been central in the framework of automated cartography. The quality and efficiency of label placement have great influences on the expression and understanding of maps. Although many algorithms have been developed to address the labelling problems of point features, very little work has been directed towards those of line...
Conference Paper
Full-text available
As the economic development of China, the demands of land resources are growing rapidly. For this reason, the land development is extending to 3D space. In order to manage the 3D space of land use, 3D cadastral management is needed urgently in China. Modeling of the 3D cadastral objects is always the core in the research of 3D cadastre. For the sak...
Article
Land use and land cover change (LUCC) plays an important role in the evolution of the global environment and sustainable development. Land use is related to natural geography and human actions, and the factors during some period are mainly studied in LUCC. Most researches are concerned about rural area but few about urban fringe area. In this paper...
Article
Expression of spatial topological relationships is regarded as one of main topics in GIS, and has achieved some distinct progresses, among which the 9-intersection model is well known. The 9-intersection model can also be extended to describe topological relationships of change things, which are called spatio-temporal topological relationships. Cad...
