After concluding years' United Kingdom of Great Britain in addition to Northern Ireland election many of the best mapped visualizations of the results used 2nd hexagon grid maps. Esri has instantly taken this a phase farther yesteryear adding an extra dimension to practise a 3d hexagonal cartogram of the 2015 United Kingdom of Great Britain in addition to Northern Ireland election results.
Political districts are normally based on equal population areas in addition to non on equal geographical areas. The consequence of this is that densely populated urban areas traditionally conduct maintain to a greater extent than election districts yesteryear expanse than less populated rural areas.
This tin introduce a work when visualizing election results using a traditional choropleth map, For example, inwards the United Kingdom of Great Britain in addition to Northern Ireland the Conservative Party traditionally performs amend inwards rural areas in addition to the Labour Party gets to a greater extent than votes inwards inner cities. Therefore if yous color election districts on a map based on the winner inwards each district yous tend to introduce a motion painting of the United Kingdom of Great Britain in addition to Northern Ireland where nigh of the Earth appears to conduct maintain voted Conservative - fifty-fifty if the election consequence is genuinely much closer.
Hexagon grid maps help to overcome this work yesteryear ignoring the geographical size of each election district in addition to presenting each district as an every bit sized hexagon. Geographically accuracy is thence partly sacrificed inwards favor of a to a greater extent than accurate representation of the give away of election districts won yesteryear each political party.
The Political Causeway - United Kingdom of Great Britain in addition to Northern Ireland Election Results, created yesteryear Esri's Kenneth Field, overlays a 3d hexagonal cartogram on run yesteryear of a 3d map of the UK. The master copy wages of using 3d cartograms is that the map tin non alone present the winners inwards each election district but tin likewise correspond voter turnout in addition to the percent of votes won yesteryear each party.
On the map 4 layers of stacked hexagons present the give away of votes cast for each political party. The peak of each hexagon represents voter turnout. The winner of each district appears on run yesteryear of the stack in addition to the colors correspond the political parties.
The disadvantage of such an approach is that yous tin alone genuinely run across all 4 stacked hexagons inwards election districts merely about the border of the map. In election districts that seem inwards the pump of the Earth yous tin alone run across the run yesteryear stack. The map overcomes this work yesteryear allowing yous to plough each of the 4 layers inwards the stack on & off. The map likewise allows yous to sentiment the election results as nested, proportional symbols. This allows yous to sentiment the map as a to a greater extent than traditional 2D hexagonal cartogram, from above.
