Diese Animation zeigt 105 datierte Kartenstaaten zwischen 1605 und 1900. Ich habe sie für erstellt Salz und Bodenein historisches Strategie-/Rollenspiel über eine Familie, die in einem sich verändernden Nordamerika lebt.
Es gibt keinen einzigen vollständigen GIS-Datensatz, der diesen gesamten Zeitraum abdeckt. Ab 1783 verwende ich datierte verallgemeinerte Staats- und Territorialpolygone aus dem Newberry Atlas of Historical County Boundaries. Frühere Jahre mussten anhand von Siedlungsdaten, Verträgen, Kontrollübertragungen und geografischen Ankerpunkten wie Jamestown, Quebec, Acadia, St. Augustine, New Netherland, New Sweden, den St. Lawrence- und Mississippi-Systemen sowie El Camino Real rekonstruiert werden.
Eine der schwierigsten Entscheidungen war die Entscheidung, was ein farbiger Bereich bedeuten sollte. Frühe Karten zeigen oft enorme Charteransprüche, die vor Ort nie wirksam kontrolliert wurden. Für diese Visualisierung habe ich versucht, die Abwicklung und wirksame Kontrolle zu zeigen, anstatt einfach jeden Anspruch auf Papier auszufüllen. Ich behielt auch einige von den Ureinwohnern kontrollierte und umstrittene Grenzregionen, in denen es keine unterstützende Siedlung, Post oder Korridor für einen Kolonialanspruch gab.
Die fehlenden Jahre werden nicht reibungslos interpoliert. Ich habe Snapshots rund um die von den Quellen unterstützten Änderungen erstellt und die Animation speichert den aktuellsten datierten Snapshot bis zum nächsten.
Wo keine vollständigen frühen Polygone existierten, hatten datierte historische Anker Vorrang. Eine frühere handverfasste Kontrollkarte wurde nur als eingeschränkte Geometriereferenz verwendet, wenn sie mit unabhängig definierten Chronologie- und Geographieregeln übereinstimmte. Dies ist eine Rekonstruktion und keine Behauptung, dass jede Grenze präzise oder allgemein vereinbart sei.
Die gleiche Karte enthält auch physische Geographie, große Flüsse, 160 datierte Stadtstandorte, Gelände und Ökoregionen, Klimakategorien, modellierte Bevölkerungsdichte und lokale historische Ereignisse. Das Kombinieren von Quellen mit unterschiedlichen Projektionen, Formaten, Maßstäben und Vorstellungen davon, was eine Grenze darstellt, war viel aufwändiger als das Zeichnen der endgültigen Polygone.

Historical chronology and location cross-checks included US Census territorial-acquisition maps, Library of Congress timelines and National Park Service histories. The early-period reconstruction also uses event-specific sources for individual settlements, treaties and transfers.
Climate categories were cross-checked against NOAA/NCEI, Natural Resources Canada and INEGI references.
**Tools and processing**
Python, Shapely, PyProj, Pillow and a custom deterministic rasterizer. The source geometry was combined in WGS84, reprojected to a custom North America Albers Equal Area projection and rasterized onto a 216×540 staggered-isometric grid.
The animation contains 105 prepared snapshots from 1605 through 1900. Between those dates, it carries the latest state forward rather than morphing or inventing annual boundary movement. Pre-1783 geometry is explicitly a source-constrained reconstruction; dated Newberry polygons have priority from 1783 onward.
Modeled population density and categorical climate layers are game layers, not direct official historical measurements.
this makes me laugh at all those people that are like „omg the current world is changing so rapidly“
Why would you say this shows effective control rather than paper claim only to highlight almost the entirety of Louisiana territory as French? Apart from a few select cities like New Orleans and St. Louis, most of it was just a claim to prevent other Europeans from interfering with very little actual control.
Should probably just say “United States” instead of “North America” since most of Mexico and Canada are excluded from view
Why is it titled „North America“ but ony shows the entirety of one single country?
I took AP US history in about 15 years ago and I don’t remember them ever teaching us about Comancheria.
Why show the French controlling the whole Louisiana purchase in the 1730s-1750s but not later in the 1700s but before they sold it to the US? It seems like you’re mixing and matching between actual control and claimed control(lines on maps, but not in real life)
Native lands should be changed to known bubbles of tribes.

This is I think the important thing to keep in mind when considering American expansionism during this phase.
Yes, obviously most of this land was actually under the effective control of the Native Americans, but the fact that the whole continent was pretty much carved up between major powers in Europe before the United States was even half it’s ultimate size, means that from the perspective of the United States when they were pushing to the Californias, a massive factor was that were securing their interests from those of France Britain and Spain, rather than just conquesting all of the natives for the sake of it.
I’m pretty sure the United States would have moved to conquer the natives in the fullness of time even without the other superpowers pressuring them to colonize it faster than anyone else had any opportunity to though.
I feel like if you list „Comancheria“ and „Apache Territories“ then you should list all of the other native groups instead of lumping them together as „Native Lands“.
Apparently there were no „natives“ in Spanish controlled territories. I hate maps like this…
I wish I could pause this or something
What I did not know before seeing this is that there was a Swedish colony in the US colonialism period. I looked it up that it mainly lasted just 17 years before the Dutch overtook it. Though the Swedish colony is probably largely responsible for spreading the building of log cabins to the US. Which later became a frontier staple. That is a cool little legacy.
Interesting choice singling out the Comanche and Apache, given the Haudenosaunee and Lakota probably retained total political sovereignty longer, and in the case of the Lakota, over a greater territory.
Would be cool to see this continued with subfaction political control; for exmaple, North/South in the civil war, factory towns and worker uprisings throughout the industrial revolution, the political factions within the US fed, etc
