Create your own: distorted map (cartogram)

  • There are currently no commercial applications that create cartograms, although some routines are available on the web from Cartogram Central and World Mapper.

Carbon atlas cartogram

Screenshot for 'Carbon atlas cartogram'
Cartograms are distorted maps, where the geographic areas represent data values, but retain (at least some) similarity in shape to the original map. The Cartogram above shows each country of the world, with the circle size representing annual carbon emissions, the World graphic at the top-right used to establish colours used for continents, and the bar-chart and table at the bottom showing data values in ranked order.

Cartogram (distorted map) showing recorded crime counts

Screenshot for 'Cartogram (distorted map) showing recorded crime counts'
The two maps both show levels of recorded crime across Leicestershire at Lower Super Output Area LSOA level (with darker red representing higher levels of crime). The map on the left shows the actual geography of the LSOA areas across the County. LSOA areas each contain roughly 1,500 residents - larger areas on this map therefore represent rural areas with lower-density population. The cartogram, or distorted, map on the right shows the same data at LSOA level, but represents each of the LSOAs as a fixed size hexagon. This avoids the problem of over-emphasising the more rural LSOAs, seen on the left. However, it becomes more difficult for users to understand which areas are which - so a numbered key is used to identify particular areas.
