Ready-to-use multi-layer topojson files.
|
|
|
|
**-->** Go to [Natural Earth CHANGELOG](https://github.com/nvkelso/natural-earth-vector/blob/master/CHANGELOG)
|
|
|
|
This project encompasses the three step required to turn
|
|
[Natural Earth Data](http://www.naturalearthdata.com/) into topojson files.
|
|
|
|
These are:
|
|
|
|
- `npm run wget`: download to Natural Earth shapefiles and unzips them
|
|
- `npm run shp2geo`: clip and convert shapefiles into geojson files
|
|
- `npm run geo2topo` add properties and convert the geojson files into topojson
|
|
files
|
|
|
|
### Usage
|
|
|
|
```
|
|
npm install sane-topojson
|
|
```
|
|
|
|
and import/require the `index.js` or the one of the `dist/` files.
|
|
|
|
### Layers
|
|
|
|
A topojson with the `objects` field:
|
|
|
|
```js
|
|
{
|
|
coastlines: {
|
|
type: '',
|
|
geometries: []
|
|
},
|
|
countries: {
|
|
type: '',
|
|
geometries: [
|
|
{type: '', id: '', arcs: [], properties: {ct: [lon, lat]}},
|
|
// ...
|
|
]
|
|
},
|
|
lakes: {
|
|
type: '',
|
|
geometries: []
|
|
},
|
|
land: {
|
|
type: '',
|
|
geometries: []
|
|
},
|
|
ocean: {
|
|
type: '',
|
|
geometries: []
|
|
}
|
|
rivers: {
|
|
type: '',
|
|
geometries: []
|
|
}
|
|
subunits: {
|
|
type: '',
|
|
geometries: [
|
|
{type: '', id: '', arcs: [], properties: {ct: [lon, lat], gu: 'ISO-3'}},
|
|
// ...
|
|
]
|
|
}
|
|
}
|
|
```
|
|
|
|
where `id` is the ISO-3 code for the `countries` layer and two-letter postal
|
|
code for the `subunits` layer. In `properties`, `ct` is the longitude and
|
|
latitude coordinates (in degrees East and degrees North respectively) of the
|
|
centroid of the geometry's largest polygon in area and `gu` stands for the
|
|
"governing unit" for `subunits` features (i.e. the country where the subunit
|
|
is).
|
|
|
|
### Development dependencies
|
|
|
|
- Install gdal (info:
|
|
[ubuntu](http://www.sarasafavi.com/installing-gdalogr-on-ubuntu.html) |
|
|
[mac](https://trac.osgeo.org/gdal/wiki/BuildingOnMac))
|
|
- `npm i`
|
|
|
|
### Configuration
|
|
|
|
In `./config.json`:
|
|
|
|
- `resolutions`: array of resolutions to output
|
|
- `scopes`: array of scopes to output
|
|
|
|
sane-topojson will output `resolution.length` times `scopes.length` topojson
|
|
files.
|
|
|
|
- `vectors`: array of layers making up each topojson file
