Transforming Layers
The Layer Object provides a number of methods for filtering layer data namely:
- bufferGeometry
- changeProperties
- clearFilters
- clipByFeatureCollection
- convertToCentroids
- filterByBoundingBox
- filterByFeatureCollection
- filterByNearest
- filterByText
NOTE: Because the Layer Object implements method chaining, multiple filters can be applied to a layer.
JavaScript
window.onload = function () {
var map = new Mapzania.Map("map-div", "AFRICA", function () {
map.usingLayer("COUNTRIES")
.clearFilters()
.filterByNearest(point, {take: 5})
.bufferGeometry(1.5)
.convertToCentroids()
.update();
};
The following interactive examples show this in action:
