Software solutions for statistical data representation in GIS by combining symbologies
Journal Title: Romanian Journal of Human - Computer Interaction - Year 2011, Vol 4, Issue 1
Abstract
Various types of cartograms in the geographic information systems (GIS) present elements from reality, being in interdependence with their location. The problem of representation of a large set of information on the cartograms is of actual interest because the user can perceive the reality through its many graphic features. The paper aims to present a series of techniques to build cartograms by combining symbologies in a GIS. The possibility to combine symbologies is based on the fact that, in addition to surface filler simple symbologies, there are overlapping symbologies, aiming to draw graphical objects on spatial data of polygon type. Thus, the user may perceive in addition to the background colour, which quantifies a characteristic of reality, other features represented by overlapping elements, like charts, symbols with various size, or dots with different densities.
