Abstract: A data visualization system is disclosed that includes a data value memory, a display, and contour generator. The data value memory maintains a finite set of data values. The display is arranged to display a representation of each data value centered on respective data points. The contour generator is arranged to generate and display a representation having a cross-sectional shape of a bell-shaped curve in which each data point is displayed as an apex of the bell-shaped curve. Also disclosed is a method of data visualization and a data visualization computer program.

Abstract: The invention provides a data visualization system comprising a data value memory in which is maintained a finite set of data values and display means arranged to display a contoured representation. One or more of the data values are displayed as contours around one or more data points and each data value is centered on a data point. The invention also provides a method of data visualization and a data visualization computer program.

Abstract: The invention provides a spatial data management system comprising a memory in which is maintained a spatial database of position data representing the position of one or more objects; retrieval means arranged to retrieve the position data representing one or more objects from the spatial database; display means arranged to display to a user a graphical spatial representation of one or more objects generated from the position data; editor means arranged to enable the user to edit the graphical spatial representation displayed by the display means; and updating means arranged to store in the spatial database position data representing the edited spatial representation. The method also provides a method of spatial data management and a computer program for spatial data management.
