Plotmap: a line-based world map generator

Create vector line (world) maps suitable for pen plotters. Data sources include GEBCO elevation data and OpenStreetMap coastlines.

Prerequisites

• Postgres including postGIS
• Python >= 3.12
• ~30 GB of disk space

Run

Build a map with a rather small config file:
python3 lineworld/run.py
This may take a while to download the GEBCO elevation data.

Convert the output SVG to gcode files, layer by layer:
python3 svgtogcode.py Lineworld750x500.svg
