Displaying Large Amounts of Spatial Data in GIS
Data visualization based on geographic maps introduces issues when lots of geo-spatial data have to be shown. These issues are caused by usual non-uniform density of the data. Map symbols that have to be seen can overlap in some parts of the map and become unclear ; on the other hand, there can be poorly filled, unused space on the map. This paper proposes a method for continuous area deformation dependent on the amount of information (attributes) that need to be displayed. Two instances of algorithm have been realized, one that shows qualitative results and the other that generates results faster. This shows practical realization of different map visualization using cartograms where different layouts can be realized with adjustable application parameters that can manipulate with results area, shape and topology.
