The website hasn't quite caught up yet: just awaiting approvals before we jump straight to publishing a 3.2 release, complete with a Reconciliation API, hopefully in the coming week.

Thank _you_ for entrusting this exceptionally challenging and rewarding project to me, @kgeographer.bsky.social !

Sounds amazing!

I'm curious to see how closely the cross-Channel route and timing match this 4-or-5-day wind-and-current-based prediction from docuracy.github.io/Historical_S...

That's not what I see. Apply those unemployment rates to mid-career wages and it's evident that humanities are not a "safe financial bet". The situation is even worse when you factor in underemployment and investment in graduate degrees.

... 📖 All of the code for extending coverage can be found together with an outline of the methodology at github.com/docuracy/His.... [3/3]

... 📱It works better on mobile devices now too, using Mercator projection instead of globe, and with an initially-minimised Options panel. The routes and all parameters used can be exported for use in other GIS applications. [2/3]

... Time of year makes a big difference too.

Monthly-weighted graphs are switched and new routes computed in less than half a second, all within the browser.

... I need yet to tune the weighting of various parameters, but it’s striking how the same principles that shaped trans-Atlantic triangular trade routes in the age of sail apply on a more local scale too: prevailing winds, swell, waves, and currents all make return routes diverge from outbound ones.

... 🌊Each cell now has bathymetry and DEM-based clear-weather land-visibility data; also month-wise indicators of hourly-average wind, waves, surface current, and nocturnal+meteorological attenuation of visibility.

Thanks to @viabundus.bsky.social and @alexislitvine.bsky.social for inspiration!

... using this graph of interconnected H3 (Hexagonal Hierarchical Geospatial Index) cells, I've computed and plotted a speculative historical sea route from Kilcolgan Castle to Faxfleet in under 2 seconds, all running in the browser. No server infrastructure or internet connection needed! ⛵

My understanding is that in respect of markets and fairs such charters granted rights rather than obligations. Historical legal sources (e.g. Chitty, 1820) focus on forfeiture for misuse rather than non-use: there was not legal compulsion to operate what became unprofitable or impractical.
