tile-workers

This project contains workers for both live rendering and seeding of map tiles.

Prerequisites

The following third-party software are required and must be installed for the tile workers to function:

• Java 8
• Vips
• PngQuant

Install

$ npm install -g @eniromaps/tile-workers

Examples

Start a live rendering worker for nautical tiles:

$ live-worker \
     --layer nautical \
     --data /data/nautical \
     --graphics /data/graphics/nautical \
     --layout /data/layout/wcm_nautical_layout.xml

Start a live rendering worker for retina map tiles:

$ live-worker \
     --layer map2x \
     --data /data/map \
     --graphics /data/graphics/map2x \
     --layout /data/layout/wcm_layout.xml \
     --dpr 2 \
     --linescale 0.75 \
     --tilesize 512

Start a worker for seeding of nautical tiles:

$ seed-worker \
     --layer nautical
     --data /data/nautical \
     --graphics /data/graphics/nautical \
     --layout /data/layout/wcm_nautical_layout.xml \
     --aws_bucket <aws_bucket> \
     --aws_key <aws_key> \
     --aws_secret <aws_secret>
