The Food Assembly is a European arrangement which brings together local nutrient producers alongside local consumers. The Food Assembly has created such groups throughout Europe, enabling consumers to come upwards together in addition to purchase locally sourced food.
You tin uncovering your nearest nutrient assembly on the Food Assembly's searchable Mapbox powered map. The map includes a actually interesting mark clustering scheme which groups together nutrient assemblies yesteryear percentage in addition to country.
Nearly all of the existing mark clustering libraries are based on a proximity algorithm which groups together markers purely on their geographical proximity. The work alongside this sort of proximity approach to mark clustering is that it ignores administrative in addition to political borders in addition to regions.
For example, using a proximity algorithm roughly markers inward 'Country A' may live on grouped together alongside markers from 'Country B' because they are geographically close, piece other markers inward 'Country A' may live on clustered alongside markers inward 'Country C' because they are closer geographically to 'Country C' than other markers inward 'Country A'.
Map users silent are used to province in addition to regional borders. H5N1 mark clustering solution which groups makers based on province in addition to regional borders may look to a greater extent than natural to the user. In such a mark clustering scheme all the markers inward 'Country A' volition live on inward 1 cluster, all the markers inward 'Country B' volition live on inward a classify cluster in addition to all 'Country C' markers volition live on inward another. Place these clusters at the centroid of each respective province in addition to the user tin clearly state which markers are inward which country.
The Food Assembly has developed such a mark clustering solution, clustering markers based on administrative in addition to political borders in addition to regions. At the lowest zoom levels the map clusters markers yesteryear country. Zoom inward on the map in addition to the markers hence expire clustered yesteryear region. Only when you lot actually zoom inward on the map does the Food Assembly switch to a proximity algorithm which ignores administrative borders.
