# JSON to GeoJson.
This converts a certain forms of JSON
to
[GeoJSON](http://www.geojson.org/), with [nodejs](http://nodejs.org/).
* the original data structure is preserved as the properties in GeoJson.
## Using it as a console utility
* Install [Node.js](https://nodejs.org/en/download/)
* Node.js makes use of `npm`, which should be part of the install
* download dependencies with `npm install -g`.
* Run this to test
```js
> ./cli.js test/results.json > test/results.geojson
```
-----
-----
### If your JSON is metadata.json
* generated from [Maptiler](http://www.maptiler.com) or [gdal2tiles](https://github.com/roblabs/gdal2tilesp)
This JSON is converted to this example [Geojson](./test/metadata.geojson)
```js
{
"name": "324511630_Descanso",
"description": "Descanso Ranger Station, 7.5 minute quadrangle of 32 45', -116 30'",
"version": "1.0.0",
"attribution": "",
"type": "overlay",
"format": "png",
"minzoom": "11",
"maxzoom": "15",
"bounds": "-116.625,32.7499998291,-116.500000129,32.8749999991",
"scale": "1",
"profile": "mercator"
}
```
-----
### If your JSON is a results array of this from
```js
{ "results": [
{
"data": 17,
"data1": "2006-04-23T19:32:42.469Z",
"data2": 2.253802555866411,
"latitude": 1.2,
"longitude": 2.3,
"data3": 16.2,
"data4": "some-data",
"data5": "2004-04-23T19:32:42.469Z",
"data6": 20
}
]
}
```
Which generates the following GeoJSON
```js
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"properties": {
"data": 17,
"data1": "2006-04-23T19:32:42.469Z",
"data2": 2.253802555866411,
"latitude": 1.2,
"longitude": 2.3,
"data3": 16.2,
"data4": "some-data",
"data5": "2004-04-23T19:32:42.469Z",
"data6": 20
},
"geometry": {
"type": "Point",
"coordinates": [
2.3,
1.2
]
}
}
]
}
```
