Notes on creating and serving raster tiles (Fall 2018)

Options to consider

1. Cutting edge - host file on S3 and serve tiles with lambda

Untested but very interesting, see:

Manually building a tile server

This page describes how to install, setup and configure all the necessary software to operate your own tile server. The step-by-step instructions are written for Ubuntu Linux 12.04 LTS (Precise Pangolin), however they should transfer fairly straightforwardly to other versions of Ubuntu or Linux distributions.

##Software installation The OSM tile server stack is a collection of programs and libraries that work together to create a tile server. As so often with OpenStreetMap, there are many ways to achieve this goal and nearly all of the components have alternatives that have various specific advantages and disadvantages. This tutorial describes the most standard version that is also used on the main OpenStreetMap.org tile server.

This guide covers installation of osm2pgsql, loading a PostgreSQL/PostGIS database, and rendering tiles for an online webmap.The database can also be used to [develop stylesheets], or render data with other software.

Before starting you want t

	- get the latest data from nomads.ncep.noaa.gov unless we have it already
	- generate file /maps/wms/data/windy.json
	- generate windy.latest file with time stamp

	""" Minimal MapProxy Middleware demonstrating the decorate_img API

	To run:
	1. Install MapProxy in a virtual enviroment together with Gunicorn
	2. Create a basic MapProxy config and copy this file into the same directory as mapproxy.yaml
	2. Activate virtual environment
	3. Change to the directory containing this file
	4. Run:
	gunicorn -k eventlet --workers=1 --log-file=- mapproxy_decorate:application
