An experimental spatial information system
… features on a map is complicated by the spatial properties not found in typical alphanumeric data. We have designed an entity-oriented relational system for representing the cartographic data, using the concept of spatial data structures. Each geographic entity such as a region, road, or …

An experimental spatial information system
In this thesis we describe a spatial information system. A spatial data structure is used as the building block of the system. Prototypes, a high level query language and an associated retrieval scheme particularly designed for the hierarchical and relational spatial data structure are discussed.

Spatial information system for public transport
… services planning. As some of the data is spatial in nature, a spatial information system is proposed as the best tool for capturing, storing and analysing the data.

An experimental disk-resident spatial information system
… structure of the experimental disk-resident spatial information system developed for this project. As will be seen, this experimental system combines features of existing relational databases with new approaches to represent and manipulate information in a database. The Query Language …

Advanced spatial information processes: modeling and application
Making full use of spatial information is an important problem in information-processing and decision making. In this dissertation, two Bayesian decision theoretic frameworks for context classification are developed which make full use of spatial information. The first framework is a new …

Multi-scale data storage schemes for spatial information systems
… multi-scale representation of integrated spatial data. Spatial information systems will benefit from having data models which allow for data to be viewed and analysed at various levels of detail, while the integration of data from different sources will lead to a more accurate …

Evaluating Head Gestures for Panning 2-D Spatial Information
New, often free, spatial information applications such as mapping tools, topological imaging, and geographic information systems are becoming increasingly available to the average computer user. These systems, which were once available only to government, scholastic, and corporate institutions with …

Supporting Learning through Spatial Information Presentations in Virtual Environments
… share the challenge of providing learners with information within 3D spaces, few researchers have investigated what approaches are used to help learn new information from 3D spatial representations. It is not understood how well learners can take advantage of 3D layouts to help understand …

Strategic revegetation planning in an agricultural landscape: A spatial information technology approach
… This dissertation represents an application of spatial information technologies to environmental management. It makes a significant contribution to the integration of general landscape-scale principles into restoration ecology. New and established quantitative, spatial analytical techniques are …

Development and evaluation of a self-instruction method for analysing spatial information
… consequences of problems related to analysis of spatial information at secondary school in South Africa, arising from historic inadequacies of human and material resources, are investigated. The post-apartheid education policy revision provides for improved spatial competence but a search for …

Effects of Spatial Information on Estimated Farm Nonpoint Source Pollution Control Costs
… will be targeted as a source of P reductions. Spatially variable physical and socioeconomic characteristics of a watershed and its occupant farms affect both the decisions made by farmers and the transport of nutrients. Evidence suggests that spatially variable characteristics should be …

Exploring The Fate Of No Longer Relevant Spatial Information Using A Modified Sternberg Task
… it enables us to update previously incorrect information in our memory, and It gives us the opportunity to move on from unpleasant past experiences.

Transient sound intensity measurements for evaluating the spatial information of sound fields in reverberant enclosures
… features of the enclosure. To meet such a need, information about the directional characteristics of sound is required. The spatial distribution of sound energy is usually not considered due to lack of an efficient, accurate and easy to perform measurement method. The main objectives of the …
