@pagasa-parser/formatter-signals

This plugin for pagasa-parser allows for the creation of colored SVG maps with appropriate legends including a province's current Tropical Cyclone Warning System level. It is aimed to be a faithful recreation of the PAGASA-provided signal maps, albeit with a higher (vectorized) quality and configurability.

Some processing is done in different stages of execution:

• Pre-runtime:
  • Initializing static features of the map, such as changing its background color.
  • Building the package for use.
• Runtime:
  • Actual execution and processing of the Bulletin object.
  • Changing the colors of each province on the map to their respective TCWS levels.
  • Cropping the map only to include parts which have raised signals, with extra space for legends.
  • Changing the stroke width for municipalities and provinces for clarity on smaller scales.
  • (to do) Adding the legends and province names.
  • (to do) Rendering the image, if creating a raster file.

Developing

Make sure to run node scripts/map-generator.js to generate the base map. If you're using the npm package, there's no need to perform this step as the base map is prepackaged.
