Simple demonstration of searching GBIF by drawing on a map. Once a shape is drawn, we use it as the geometry parameter to query GBIF's API. The first 300 occurrences are displayed. Uses Leaflet.draw to draw shapes, and Wicket to convert GeoJSON shape to the WKT format required by GBIF's API. Used Leaflet.draw plugin with options set by d3noob as a starting point.
