Installing the library

All releases of this package are listed in the release list on github here. To install this library, simply find the latest .js file in there, and put it in the directory of your project.

Import the ellipsis library in leaflet project

with script tags

<!-- Import leaflet -->
<link
  rel="stylesheet"
  href="https://unpkg.com/leaflet@1.7.1/dist/leaflet.css"
/>
<script src="https://unpkg.com/leaflet@1.7.1/dist/leaflet.js"></script>
<!-- Import ellipsis library -->
<script src="https://github.com/ellipsis-drive/ellipsis-js-util/releases/download/1.1.0/ellipsis-js-util-1.1.0.js"></script>
<script src="https://github.com/ellipsis-drive/leaflet-package/releases/download/3.1.0/leaflet-ellipsis-3.1.0.js"></script>

with npm npm install leaflet-ellipsis

Add an ellipsis-drive map to leaflet map

Example

const map = L.map("map", {
  center: [51.505, -0.09],
  zoom: 13,
});

// Raster layer
new leafletEllipsis.EllipsisRasterLayer({
  pathId: pathId, timestampId:timestampId, style:styleId, zoom:zoom  token: yourToken,
}).addTo(map);

// Vector layer
new leafletEllipsis.EllipsisVectorLayer({
  pathId: pathId,
  token: yourToken,
}).addTo(map);

The timestampId and style are required for raster layers, you can use AsyncEllipsisRasterLayer in order to make use of defaults suggested by the server.

const createEllipsisRasterLayer = async () => {
  const someRaster = await leafletEllipsis.AsyncEllipsisRasterLayer({
    pathId: pathId,
  });
  someRaster.addTo(map);
};

createEllipsisRasterLayer();

In this case only the pathId is required.

Obtaining tokens

To use layers that are not set to public or link sharing you need to pass a token as a parameter. See here for how to obtain such a token.

RasterLayer options

note for the style object, refer to this documentation about it.

A raster layer is equiped with a getColor function. You can use this function to get the pixel values of a certain point. The input should be an object with properties lat and lng both as float.

In this example the raster value of the layer is logged on mouse hover:

const layer = new EllipsisRasterLayer({
  pathId: "552c92e8-8422-46eb-bb55-1eb39e18eee9",
  timestampId: "a19ef596-c48b-479e-87f5-b808cf6fb4d3",
  style: "5b2deacd-a1e3-4b3f-b53a-ae05a0c7fd8d",
  zoom: 14,
});

map.on("mousemove", function (event) {
  var a = layer.getColor(event.latlng);
  console.log("A", a);

});

layer.addTo(map);

VectorLayer options

note for the style object, refer to this documentation about it.
