How-to add a GeoJSON file

Getting a GeoJSON file

GeoJSON files are stored statically! No MapServer is involved in the serving or rendering of a GeoJSON file with GeoMoose.

A great example is the cities.geojson file. It can be downloaded from here and placed in the the workshop/ directory.

Add the new map-source

In mapbook.xml after line 5 add:

<map-source name="cities" type="geojson">
    <url>./cities.geojson</url>
    <layer name="all-cities">
        <style><![CDATA[
        {
            "circle-radius" : 5,
            "circle-color": "blue",
            "text-font": ["Arial", "Open Sans Regular"],
            "text-field": "{city}",
            "text-jusitfy": "right",
            "text-anchor": "right"
        }
        ]]></style>
    </layer>
</map-source>

Add cities to the catalog

• Find <catalog> in the mapbook.

• After the <catalog> tag add:

  <layer src="cities/all-cities" title="World Cities" />
  

Important notes on GeoJSON layers

1. They cannot yet be used for querying.

2. They are styled using a subset of MapBox GL Styles.

The package used by GeoMoose to translate the MapBox GL styles to OpenLayers styles is actively being updated and GeoMoose will follow its progress.
