How to Upload a Geojson File to Mapbox Api

Past Sean Gillies

GeoJSON is an open up format for encoding information nigh geographic features using JSON. It has much in common with older GIS formats, but also a few new twists: GeoJSON is a text format, has a flexible schema, and is specified in a single HTML page. The specification is informed by standards such equally OGC Elementary Features and Web Feature Service and streamlines them to accommodate the style web developers actually build software today.

Promoted past GitHub and used in the Twitter API, GeoJSON has become a big deal in the open spider web. We are huge fans of the little format that could. GeoJSON suits the web and suits the states very well; information technology plays a major office in our libraries, services, and products.

Mapbox.com

Download of your MapBox project markers as GeoJSON is simply a single click from the details tab of whatsoever project.

MapBox API

You tin go the same marker GeoJSON from the MapBox API. The map resources section of the Core API documentation shows the URL template to follow.

URL Clarification /:map/markers.geojson api.tiles.mapbox.com/v3/mapbox.o11ipb8h/markers.geojson Markers GeoJSON for :map

Geojson.io

As you might look from its name, geojson.io reads and writes GeoJSON data. You can load GeoJSON through the UI every bit shown below,

or pipe it in via data URIs similar geojson.io/#information=data:text/10-url,http://api.tiles.mapbox.com/v3/mapbox.o11ipb8h/markers.geojson.

Leaflet and MapBox.js

Leaflet is a JavaScript library for mobile-friendly maps and MapBox.js is a Leaflet plugin. The pair firmly encompass GeoJSON; it is the only data format included in the core of Leaflet. Both of these libraries include excellent GeoJSON examples: Using GeoJSON with Leaflet, GeoJSON Marker from URL (mapbox.js).

GeoJSON support arrived in Leaflet after the the library had settled on latitude, longitude order for coordinates returned from functions like Map.getCenter(). There's a coordinate guild partition in Leaflet and MapBox.js: [lng, lat] within L.geoJson() and [lat, lng] outside; respect this division and you'll have no trouble. If y'all maintain your GeoJSON data in text, all [lng, lat] ordered coordinates volition be isolated in that location. You can then develop your mapping JavaScript thinking only in terms of [lat, lng].

The functions L.geoJson() and L.mapbox.markerLayer() accept objects that may be serialized to valid GeoJSON Geometry, Feature, or FeatureCollection text. To get GeoJSON text into your map, use markerLayer.loadURL().

MapBox iOS SDK

One of the best parts about using simple, open up formats like GeoJSON is that we're not fifty-fifty limited to the open spider web. For as long as we've had markers bachelor as GeoJSON from our API, we've also supported bringing those markers into native iOS apps. Apple'southward Cocoa frameworks have supported native JSON parsing with NSJSONSerialization for several years now, and our open source iOS SDK builds atop this in RMMapBoxSource for bringing your MapBox maps and their markers into native apps. We have an example app, Weekend Picks for iOS, that shows this in action, with markers designed in our web editor being automatically turned into kickoff form native objects in iOS code. This could allow simple editing of a web map to translate into updates to a real, native iOS app in the field.

What's more than, yous can use straight GeoJSON every bit well, including lines and polygons, as in this example from our code library. Here we iterate the features array directly, parsing out geometry objects and their coordinates. Take notation that Apple's convention when building CLLocationCoordinate2D structures, every bit in Leaflet, is latitude, and so longitude.

TileMill

TileMill has long supported GeoJSON as an input format. Add together a File type layer and specify a local filesystem path or HTTP URL of a GeoJSON document — such every bit a raw URLs from a GeoJSON file on GitHub or a MapBox API GeoJSON URL (as mentioned above) — and you accept a information source that tin be stylishly rendered.

Open up formats are healthier formats

In a market crowded with geospatial data formats, GeoJSON has the stardom of being the only one designed with the open spider web in mind. Information technology's also shown itself to exist useful on native device platforms. Nosotros are committed to giving y'all tools to map and share GeoJSON and to helping ensure that the format continues to flourish.
