Constraint database visualization; Isometric color bands displays


In general, visualization is any technique for creating images, diagrams, or animations in order to present any message. Scientific visualization is an application of computer graphics which is concerned with the presentation of potentially huge quantities of laboratory, simulation, or abstract data to aid cognition, hypotheses building, and reasoning.

In a spatial database system, spatial information is usually stored in the format of raster data or vector data. To visualize raster data, the visualization application has to convert the geographical information associated with each pixel into a specific color and present each pixel individually. To visualize vector data, the visualization application has to identify the geometrical primitives such as points, lines, curves, and polygons, convert the original geospatial coordinate system to screen coordinate system, associate a particular color to each...
