In GIS it is often sometimes hard to present point-based data because at times there are several different points and data symbologies that need to be shown. As the number of different data points grows they can become complicated to interpret and manage, resulting in convoluted and sometimes inaccurate maps. In order to reduce map congestion many GIS users use a process called binning. Binning is defined as the process of grouping pairs of locations based on their distance from one another.
Measurements from ESA’s CryoSat mission have been used to map the height of the huge ice sheets that blanket Greenland and Antarctica and show how they are changing. New results reveal combined ice volume loss at an unprecedented rate of 500 cubic kilometres a year.
