[](https://travis-ci.org/rubenv/topojson) [](https://godoc.org/github.com/rubenv/topojson)

https://github.com/mbostock/topojson-specification
Uses the GeoJSON implementation of paulmach:

Large parts are a port of the canonical JavaScript implementation, big chunks
of the test suite are ported as well:

## Installation
```
go get github.com/rubenv/topojson
```
Import into your application with:
```go
import "github.com/rubenv/topojson"

```
Optionally pass options as the second argument.
