GOIT-GGIT-pipeline-routes

This is a GitHub repository at Global Energy Monitor to store pipeline routes.

Individual routes are stored as [ProjectID].geojson, in the data > individual-files folder.

Every project has a GeoJSON file associated with it.

If a given project does not have a route, either because it's a capacity expansion with no actual new pipeline associated with it, or because we haven't created the route yet or cannot find a map to trace online, we STILL create a .geojson file for it, it's just stored as an empty GeoJSON file (i.e., None-type geometry).

An example of an "empty" GeoJSON file could look something like this:

{
"type": "FeatureCollection",
"crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:OGC:1.3:CRS84" } },
"features": [
{ "type": "Feature", "properties": { "ProjectID": "P6445" }, "geometry": null }
]
}

or like this:

{
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature", 
            "geometry": null
        }
    ]
}

Contribute by creating a new branch and a pull request

If you update a route or multiple routes...

1. Create a new branch with a short, informative title (for example, firstname-p9998-p9999)
2. Add your changes to the branch and push it to the repository
3. Create a pull request and assign it to Baird for review

How can I create a GeoJSON file from scratch for a route?

• If you are comfortable working in QGIS or JOSM, those are the most complex ways to do it. Create a route or edit an existing one and re-export it as a GeoJSON file. You don't need to include any specific information about the pipeline itself (name, status, etc.) in the GeoJSON file; the only way I ask you to label it is via the title: [ProjectID].geojson. (You can of course include more info, but it's not necessary.)

• If you're creating a new route from scratch, and the tools above aren't familiar, try using geojson.io or placemark.io.

• If you're editing an existing route, you can import the GeoJSON file that already exists for it

Coordinate reference system

The GeoJSON file format specification says that GeoJSON files use a WSG 84 (EPSG:4326) coordinate reference system, so this is expected for all pipelines and no crs is required in the GeoJSON file.
