3D Hexagonal Cartograms
After concluding years' U.K. election many of the best mapped visualizations of the results used 2nd hexagon grid maps. Esri has right away taken this a phase farther past times adding an extra dimension to exercise a 3d hexagonal cartogram of the 2015 U.K. election results.
Political districts are normally based on equal population areas in addition to non on equal geographical areas. The number of this is that densely populated urban areas traditionally conduct maintain to a greater extent than election districts past times expanse than less populated rural areas.
This tin strength out introduce a work when visualizing election results using a traditional choropleth map, For example, inwards the U.K. the Conservative Party traditionally performs ameliorate inwards rural areas in addition to the Labour Party gets to a greater extent than votes inwards inner cities. Therefore if y'all color election districts on a map based on the winner inwards each district y'all tend to introduce a motion painting of the U.K. where almost of the Earth appears to conduct maintain voted Conservative - fifty-fifty if the election number is truly much closer.
Hexagon grid maps assistance to overcome this work past times ignoring the geographical size of each election district in addition to presenting each district as an as sized hexagon. Geographically accuracy is thus partly sacrificed inwards favor of a to a greater extent than accurate representation of the number of election districts won past times each political party.
The Political Causeway - U.K. Election Results, created past times Esri's Kenneth Field, overlays a 3d hexagonal cartogram on overstep of a 3d map of the UK. The top dog wages of using 3d cartograms is that the map tin strength out non solely present the winners inwards each election district merely tin strength out as good stand upwards for voter turnout in addition to the per centum of votes won past times each party.
On the map iv layers of stacked hexagons present the number of votes cast for each political party. The summit of each hexagon represents voter turnout. The winner of each district appears on overstep of the stack in addition to the colors stand upwards for the political parties.
The disadvantage of such an approach is that y'all tin strength out solely truly run into all iv stacked hexagons inwards election districts roughly the border of the map. In election districts that look inwards the midpoint of the Earth y'all tin strength out solely run into the overstep stack. The map overcomes this work past times allowing y'all to plow each of the iv layers inwards the stack on & off. The map as good allows y'all to sentiment the election results as nested, proportional symbols. This allows y'all to sentiment the map as a to a greater extent than traditional 2D hexagonal cartogram, from above.
