This repository moves the dynamic pixel showing/hiding/recoloring magic from the GFW flagship site to the server-side, making true color loss and GLAD tiles more easily available.
To demo this service, try adding the following to the map on http://geojson.io (Meta -> Add Map Layer): http://production-api.globalforestwatch.org/v1/true-color-tiles/loss/{z}/{x}/{y}?thresh=75&startYear=2005&endYear=2008
The above will add loss tiles to the geojson.io map, filtering to show only data from 2005 - 2008 where thresh >=75.
This is the same mechanism that the flagship performs when users change the timeline and the TCD threshold of interest.
For an example of adding zoomable loss/glad tiles to ArcMap, see Add-Data-to-ArcMap.md

First, make sure that you have the API gateway running locally.
We're using Docker which, luckily for you, means that getting the application running locally should be fairly painless. First, make sure that you have Docker Compose installed on your machine.
