tiler-file

Circle CI

A nodejs map tile file reader coordinating by X,Y,Z.

Introduction

This is a map tile file reader for map tiles in XYZ schema.

Because the path rule to store tile files is arbitrary, a path template phrase is needed to interprate XYZ to a actual file path.

lodash is used here as the template engine. You can see how to use it in the example below.
