R3-Tile-Generator

AWS Lambda Tile Generator for R3

Goal

Fast, automated, distributed generation of map tiles for R3 using the parallel computing power of AWS Lambda.

Spawn a single Lambda Instance per required zoom level, upload tiles direct to S3, inform web client of progress through SNS.

Why not Node.js on Lambda?

Node.js was my initial attempt but every library for image manipulation I tried choked on the ~80MB test PNG files :(

As a result I’m using python and trying my hardest to keep crazy memory usage under control…

User flow

  1. Upload .emf to web interface
  2. Wait for completion of automated tile generation…
  3. Tiles automatically ready to use in R3 due to S3 remote tile hosting!
