The first king of the Kirant Kingdom Yalamber is said to be featured in the battle of Mahabharata itself. So, a distinguished identity is required.

Also, the map of ancient Nepal before 1816 AD is Sutlej in the west to Tiesta river in the east.

There seems to be a poor correlation with coastlines in many cases - for example going to 1815-1920 and looking at the United Kingdom of Great Britain and Ireland, a lot of the coastal areas (and many of the surrounding islands including the Orkneys, Shetlands, Isle of Wight and Anglesey) are excluded.

I appreciate that you want to keep the polygon size small, but this would be better done by drawing the coastal borders around the island(s) rather than inside. It won't be an accurate capture of territorial waters of the time but what it will do is capture correctly all coordinates within the territory on land, which the current data fails to do.

I'm looking at this as a way of being able to map existing data points on land and see which territories they fell into in the historical past - but these polygons currently don't do this effectively because they are clipping out significant parts of coastal regions.

Is there any intent to fix this, or will I have to fork the data and work on this myself?

Are the differences between the handling unincorporated US territories versus past colonial territories intentional? For instance, places like Puerto Rico were labeled as part of the Spanish empire at times, but are not labeled as part of the US in more recent maps

Love these sets!

Noticed that Hong Kong is missing from the 1960 map

What is the difference between the values 1 (approximate) and 2 (moderately precise) in the BORDERPRECISION field?

Also, some parts of the same boundary between two countries may be precise and undisputed, and other parts may be undemarcated (as in the case of the South Patagonian Ice Field between Argentina and Chile) or disputed (as in the case of Kashmir between India and Pakistan). Wouldn't it be better to delete this field from multipolygon maps and make separate multilinestring maps showing different parts of boundaries marked with different codes (such as undisputed, claimed or approximate) that could be visualized using different line types (solid, dashed, dotted) instead of declaring the whole country as having "approximate" boundaries and drawing it as a blurry blob (https://raw.githubusercontent.com/aourednik/historical-basemaps/master/img/historicBorders_fuzzyNonFuzzy.png)? If you are interested, I can start making them.

What is the exact purpose of the PARTOF field? Is it necessary for new contributions? Usually it just duplicates the SUBJECTO field.

Since it is usually difficult do ascribe each country to a single "larger cultural area", this field could be used to list international organizations and alliances that the country is a member of (like this: https://www.cia.gov/the-world-factbook/field/international-organization-participation/), but gathering necessary information for each year may take a lot of time.

bonjour,

bravo pour ce travail et merci pour le partage !

https://raw.githubusercontent.com/aourednik/historical-basemaps/master/world_1279.geojson is empty

So, i watched Boone Loves Video's tutorial, and i folowed eveything and have retried, i have restarted both after affects and my pc. The source is showing up, but when i search for anything, i only get places name, and not any historical maps. This is really annoying!

Hi,

What is the licensing for this data? If appropriate it seems like a valuable dataset to import / hold hands with Who's On First:

https://whosonfirst.org/

Historical data always took a back seat to other day-to-day concerns but it was (is) definitely still something we want to support:

https://whosonfirst.org/blog/2017/06/29/tackling-space-and-time-in-whosonfirst/

I notice that in 1920 (and at least even in 1960) Italy is represented with a light-grey color that make impossibile to distinguish it form contiguous Yugostlavia. The color let think that there are some data missing.

Your geojson data was used in https://github.com/nrgapple/historic-country-borders-app which was posted to reddit at https://www.reddit.com/r/dataisbeautiful/comments/l52krh/an_app_i_made_for_visualizing_country_borders/gksqcsm/

I'm not familiar enough with historical boundaries to talk on any of this with any type of authority, but you can find some threads in the post discussing boundaries such as https://www.reddit.com/r/dataisbeautiful/comments/l52krh/an_app_i_made_for_visualizing_country_borders/gkspqy6/ and https://www.reddit.com/r/dataisbeautiful/comments/l52krh/an_app_i_made_for_visualizing_country_borders/gksqcsm/

Sorry for the vagueness, but I figured it may be of interest to you.

I'm having trouble with the following geojson files:
world_1500.geojson
world_1600.geojson
world_1650.geojson
world_1700.geojson
world_1715.geojson
world_1783.geojson
world_1800.geojson

There seems to be a problem with the way the polygon borders are defined. I've attached screenshots of what "d3v5_example.html" looks like for world_1530.geojson (which looks good) and what "d3v5_example.html" looks like for world_1600.geojson (which has something going on).

1530 data:

1600 data:

Where does the coastline data for those maps come from? Maybe it would be better to redraw them using a more deatailed source, such as Natural Earth (https://www.naturalearthdata.com/), Vector Map (https://gis-lab.info/qa/vmap0-eng.html) or World Vector Shorelines (https://www.ngdc.noaa.gov/mgg/shorelines/, https://data.humdata.org/dataset/global-lsib-polygons-detailed?) (simplified, if needed, in order to reduce file size)?

Also, I tried to make my own world map based on OpenStreetMap data with coordinates rounded to 0.1 decimal degrees. It is small enough for web apps (around 3 MB) and precise enough for a printed A0 wall world map (scale around 1:30000000), but at higher zoom levels lines appear a little blocky, so I'm not sure if it's good enough.

Like in a previous issue, I saw your data reused on https://historicborders.app/ via a Reddit post. Please check out the borders of Laos in 1492, which extend across China. I'm pretty sure that should be labeled under the Ming dynasty.

What is the file encoding you use for the geojson files?

It looks like UTF-8 but some words have these ? characters. Tried a couple, in my experience the problem usually is some special windows encoding, but could not find which one it was.

Example:

Northern Ireland, politically, didn't exist until 1921, unless I'm mistaken.

Just saw you updated the data to add pre history! Do you plan on continuing to update your data?

I'd love to partner with you in adding features and making this as up to date as possible. I get around 50 hits a day on historic borders and when love to make your data a bigger part of it!

Hi, Bangladesh came into existence/independence in 1971. The map in world_1960 is showing Bangladesh which is not correct. It was part of Pakistan at that time.

Pretty much just the title.

Hi there. Great project! I have a CSV file with all the name you use for the elements translated into Spanish. If you think it might be helpful to add a translated version (or eventually add another property like "NAME_ES" or "NAME_SP" for example, just let me know and I send it over.

I've made an observable to look at your files, and with the animation it appears that there is a slight rotation on bc1

https://beta.observablehq.com/@fil/historical-basemaps-take-1

(note that you might fork my animation and ask me to take it off — it's really not ready to "publish", but it was the simplest way to share)

I suggest giving them the names "British India" and "East India Company" instead of calling both India. As it is rn, its misleading and confusing.

Would be nice to see some more history in polynesia, melanesia, and micronesia. Would be nice to see the tui'tonga empire and rapa nui.

In the interests of historical accuracy it may be useful to know which countries actually controlled which territories at a given moment of time. Also, GIS files without polygon overlaps are better for making choropleth maps. For those purposes it would be better to add separate maps with de facto country boundaries for each year. If you are interested, I can start making them.

India's area is shown part of neighbouring countries.

Hey there, here's a few issues with the borders of Austria-Hungary over the years:
- 1715, 1815, 1914 - Northern Serbia is part of Austria. Same borders as 1800, 1880
- 1815 - 1914 - Western Ukraine, including Lviv is part of Austria. See image
- 1815 - 1914 - Southern Poland is part of Austria. See image
- 1815 - Krakow is an independent republic (until 1830), 1880 - 1914 Krakow is part of Austria
