This sets up a Tessera server for use as a vector tile server for TerriaJS. It contains configuration, data and helper scripts.

• The server-version.tar.gz packages need to be created on a similar operating system (to the Amazon Linux AMI used)

• setup_layer.py: Script to add shapefile layers. Generates all neccessary TerriaMap and vector-tiles-server files and uploads the server files to S3
• deploy.py: Script to deploy the server to AWS with any subset of the layers available in the S3 bucket, based on past deployments, all newest layers, or a selection of layers

This server uses the Tessera server and tilelive module architecture. It uses various customised forks and specific modules. These are:

• Tessera – forked to allow for forked dependencies, and also stripped down (leaflet map removed and static page serving commented out)
• tilelive-bridge – forked to return 0 length buffer instead of an error when a vector tile is empty
• tilelive-hybrid – a new tilelive module that serves tiles from different tilelive sources based on the zoom level
• tilelive-cache – forked to ask tilelive-hybrid sources whether they want a tile cached or not and to change the cache duration from 6 hours to 1 year

This package depends on Mapnik which downloads pre-built binaries on install. Pre-built binaries are not available from Mapnik for all Node versions, so some Node versions may not be supported (see node-mapnik for more information). The Node versions that this package has been tested with are: Node v5.1.0, v0.12.9 and v0.10.42.
