My lockdown side project: An interactive vintage map builder

• historical-basemaps

  31 413 5.2 JavaScript

  Collection of georeferenced boundaries of world countries and cultural regions for use in mapping historical data on global or continental scale

Thanks for the compliments! The territory data is coming from https://github.com/aourednik/historical-basemaps, I use this data to render an SVG map with D3.js. This is pretty powerful since you can control every part of the rendering mechanism. With D3-geo you can easily do the projections and graticule.

• d3-geo

  6 1,000 4.8 JavaScript

  Geographic projections, spherical shapes and spherical trigonometry.

For the cities, I used the data from this paper. The rivers are pretty standard and the mountains are taken from this Github project. The sea labels are custom made by me through QGIS, I open-sourced the data.

• sea-labels

  1 3 5.0 JavaScript

  GeoJSON of multilingual sea labels positioned with curved lines

• polylabel

  1 1,384 2.8 C++

  A fast algorithm for finding the pole of inaccessibility of a polygon (in JavaScript and C++)

  

Further, the correct placement of country labels is complex. You would think just centering is enough but for some country shapes (like the Turkish Empire in 1914) this looks very out of place so I tried this algorithm but calculating it upfront proofed more accurate. I still had to program my own editor to correctly place some labels so that they are esthetically pleasing. (still not 100% done with it)

• InfluxDB

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
