LunaRender

experimental OpenStreetMap renderer. Despite its name it is used for rendering of earth surface mostly.

Work in progress. See introduction post.

NEW - I started working on more usable version - lunarender3 (based on vector tiles).

features

  • input format: OSM XML, Overpass API JSON output
  • output format: SVG
  • rendering rules scriptable with lua
  • no need for installing Postgres

installation

Download source package and unzip it. Binaries for windows are already included.

For installation under linux see this issue.

Some rendering rules uses Symbola font, it's better to install it otherwise you got mojibake.

usage

  1. go to OpenStreetMap, select some nice place and export it
  2. drop exported XML file to LunaRender working directory
  3. run cmdhere.bat (or add lunarender.bat to PATH)
  4. call lunarender map.osm from command line

using data from Overpass API

  1. go to Overpass turbo and enter your query. Note: you have to include [out:json] and [bbox:{{bbox}}] in your query.
  2. export data as raw data
  3. drop exported JSON file to LunaRender working directory
  4. run cmdhere.bat (or add lunarender.bat to PATH)
  5. call lunarender export.json from command line

command line parameters

  1. input file name - required
  2. rendering rules file name - default rules/default.lua
  3. zoom - default 15

rendering rules

Rendering rules are written in lua.

Currently there is no documentation about rendering rules. You have to look into source code of demo rules.
