GLOBO

Globo is a microservice that makes it easy to convert from lat/long to google's s2 formats.

Endpoints

tos2/point

Takes a json body that looks like this:

{
	"lat":55.00,
	"lng":55.00
}

And returns

{
    "cellid": 4890663957615284359
}

If the optional field "precision" is specified then the parent cellid with level == precision is returned.

tos2/geojson/:type

Converts a geojson :type to a collection of s2 cellIds (with the request precision/ maxnumber) + bounding box, and returns a geojson feature collection that can be displayed

Values accepted for :type: :

• point
• polygon
• multipolygon

Query parameters:

• precision integer specifies how precise the generated cellids should be, default max precision.

Note: if the any of the polygons are not CCW winded, we refuse to convert them. i.e. it's the client responsablity to send proper json.

install and build

export PORT=3001 #or wathever
go build && ./globo 

Dependecies are vendored thus requre GOVENDOREXPERIMENT=1 or go 1.6.
