Advanced tools
transform geojson with simplestyle-spec into mapnik xml
Transform GeoJSON objects into Mapnik XML stylesheets with embedded GeoJSON data and simplestyle-spec-derived styles.
As a dependency:
npm install --save @kartotherian/geojson-mapnikify
As a binary:
npm install -g @kartotherian/geojson-mapnikify
Assumptions:
If you install -g
, you can use geojson-mapnikify
as a binary that takes
a single GeoJSON file as an argument and writes a Mapnik XML stylesheet
to stdout.
$ geojson-mapnikify test/data/point-retina.geojson > stylesheet.xml
$ geojson-mapnikify test/data/point-retina.geojson retina > stylesheet-retina.xml
mapnikify(geojson, retina, callback)
Transform GeoJSON into Mapnik XML.
geojson
is a GeoJSON object.retina
is true or false for whether the style should be optimized for 2x rendering.callback
called with (err, xml)
where xml is a stringIf your GeoJSON object has one or more features with a marker-url
property, mapnikify()
will write the images found at the url into a file in a temporary directory and use that path in the Mapnik XML. This uses the request library to handle the http file fetching.
By default the request will attempt to fetch binary data from the specified url. If the url is http
and not https
, Mapnikify will use agentkeepalive to speed up requesting multiple images. There is also a default timeout of 5 seconds.
You can customize the defaults passed to request()
. Simply set a custom wrapper defined with request.defaults
. See request's documentation on defaults for more information. For a quick example, this will set a longer timeout:
var mapnikify = require('mapnikify');
var myRequest = require('request').defaults({
timeout: 10000,
followRedirect: false
});
mapnikify.setRequestClient(myRequest);
mapnikify(geojson, retina, callback);
mapnikify.setRequestClient(null); // return to mapnikify defaults
