Journal Article
Visvalingam, M., & Whyatt, J. D. (1990). The Douglas-Peucker algorithm for line simplification: Re-evaluation through visualization. Computer graphics forum : journal of the European Association for Computer Graphics, 9(3), 213-225. https://doi.org/10.1111/j.1467-8659.1990.tb00398.x

The primary aim of this paper is to illustrate the value of visualization in cartography and to indicate that tools for the generation and manipulation of realistic images are of limited value within this application. This paper demonstrates the valu... Read More about The Douglas-Peucker algorithm for line simplification: Re-evaluation through visualization.

Digital cartography is the technology concerned with the construction and use of computer-based systems for the practice of cartography and its applications. The paper starts with a brief introduction to cartography and cartographic maps. It then pro... Read More about Trends and concerns in digital cartography.

Approaches to the optimizing control problem (1988)
Journal Article
Ellis, J. E., Kambhampati, C., Sheng, G., & Roberts, P. D. (1988). Approaches to the optimizing control problem. International Journal of Systems Science, 19(10), 1969-1985. https://doi.org/10.1080/00207728808964092

The selection of the steady-state controls which enable a system to operate in an optimum manner is the optimizing control problem. An examination of direct and adaptive model-based approaches to this problem is made. In the direct approach, system m... Read More about Approaches to the optimizing control problem.

The protestant episcopal church, black nationalists, and expansion of the west african missionary field, 1851–1871 (1988)
Journal Article

The signed Chi-score measure for the classification and mapping of polychotomous data (1981)
Journal Article

Several polychotomous characteristics, when expressed in chi-score form, exhibit distributions in property space which deviate from the inherent assumptions of the more commonly used methods of cluster analysis. This paper suggests a novel approach t... Read More about The signed Chi-score measure for the classification and mapping of polychotomous data.

Making a national atlas of population by computer (1980)
Journal Article

This paper describes the conceptual and practical problems encountered and solved in producing a multi-colour atlas of population characteristics in Great Britain. The atlas itself is in A4 format; it consists of some thirty-four maps of Great Britai... Read More about Making a national atlas of population by computer.

The signed Chi-square measure for mapping (1978)
Journal Article

When interest extends beyond purely univariate considerations there is no fixed rule governing the ordering of spatial samples for mapping and statistical analysis. Ratios and numerical differences have conventionally been the basis for comparing sam... Read More about The signed Chi-square measure for mapping.

Indexing with coded deltas—a data compaction technique (1976)
Journal Article
