How To Utilisation Grid Maps - Purpose Two
Creating hexagon grid maps is real straightforward amongst Leaflet. What follows is a quick tutorial explaining how to exercise this transcend penalty Grid Map.
We tin brand a quick kickoff to the map yesteryear next the Leaflet Choropleth Map tutorial. Once yous bring the Leaflet Choropleth map, from the Leaflet tutorial, upwards in addition to running all yous bring to exercise is exercise the hexagon shaped polygons for the US states in addition to relieve it every 2nd a GeoJSON file.
Again yous tin cheat hither in addition to exactly choose handgrip of the state polygon information from the CartoDB Bee Loss map. The information is provided inwards a table view amongst a great niggling push to download the information every 2nd a GeoJSON file. Download the information in addition to yell for your Leaflet Choropleth Map to your novel GeoJSON file instead of the 'states.js' file inwards the master copy tutorial map.
We don't desire the underlying map tile to look on our map. So but delete the next business office of the html (which loads the map tiles):
Essentially that's all at that topographic point is to it.L.tileLayer('http://{s}.tiles.mapbox.com/{id}/{z}/{x}/{y}.png', { id: 'examples.map-20v6611k', attribution: ... }).addTo(map);
However it would last prissy to truly visualize roughly information on our hexagon grid map. This is tardily for a uncomplicated true or false state map.
In my instance Grid Map I've created a map which shows which states bring an enforceable transcend penalty. To exercise this I but created 2 carve upwards GeoJSON files; 1 including the hexagon shaped polygons for states amongst the transcend penalisation in addition to roughly other amongst the polygons for the states without the transcend penalty. It is in addition to thus a uncomplicated thing of applying a unlike manner to each ready of polygons (green for states without the transcend penalisation in addition to ruby-red for those states amongst the transcend penalty).
It is would every 2nd good last prissy to add together labels to our polygons thus that the map's users tin easily encounter which polygon represents each state on the map. To exercise this I used the leaflet-label plug-in. It is in addition to thus exactly a thing of creating a label at the midpoint of each polygon (to relieve doing this yourself yous tin exactly re-create & glue the label variables from my instance map).
That's it - yous should straight off bring a uncomplicated hexagon grid map of the United States, showing which states bring an enforceable transcend penalisation statute in addition to which states don't.
