Encoding and missing data errors are present for some of the lesser filled out areas of Velkscala, Confoederatio's main geospatial population databse (with Stadestér representing urban population) due to underlying errors in HYDE3.2/HYDE3.3, both of which were merged and stitched together to form backbone land use and population density graphs.
These are intended to be eventually restructured and merged with Stadestér in coordination with Operation HALIENNE, though this data processing is still in effect and has yet to be released. We present immediate action plans and known lists of errors for population data in Velkscala below. For separate errors relating to Eoscala, Confoederatio's main geospatial economic database, see Eoscala Errors.
Known errors are sorted alphabetically by time period. Not all known errors have been logged, and this is merely a sample of the most significant known population errors by region.
| Modern Jurisdiction/Region. | Time Period (Inclusive). | Description. | Error Correction/Amelioration Steps. | Severity. |
|---|---|---|---|---|
| Beirut, Lebanon | 10000BC-1000AD | Two pixels show a strangely high population relative to neighbours for what is now Beirut from 10000BC to 1000BC. | It is believed that this can be fixed using R stray pixel outlier removal (see Paris, France entry), although it may require some adjustment. | HIGH |
| Bhutan | 10000BC-1500AD | Bhutan appears conspicuously empty despite well-founded population figures, as well as relatively high density in pre-modern times relative to other Himalayan kingdoms. | Requires manual correction. | MEDIUM |
| Canada | 10000BC-1750AD | Amerindigenous population estimates reflect modern settlement patterns. | LOW | |
| Denmark | 10000BC-1000BC | Nearly all the population appears to be concentrated in Copenhagen, a clear modern encoding error. | HIGH | |
| Eastern Central African Republic | 10000BC-2025AD | Displays persistently low population relative to immediate neighbours in Chad, Northern DRC and Darfur. | Requires manual correction. | MEDIUM |
| Guatemala, Belize, and Quintana Roo | 10000BC-1900AD | Low population despite being known as the demographic centre of Mayan civilisation. This is most pronounced from 2000BC-1700AD. | HIGH | |
| Paris, France | 10000BC-1500AD | A certain pixel near Paris (Pontoise?) has massive population figures, reaching into the millions in antiquity. |
There is already an ameliorative step towards redressing this using R, with nearest neighbour pixel average sampling and outlier removal.
It remains to be implemented in the main Node.js version. |
HIGH |
| St. Petersburg, Russia | 10000BC-1700AD | Anachronistically high population prior to the city's founding. | Could be fixed using Stadestér data eventually. | MEDIUM |
| Russia | 10000BC-1500AD |
Heavy anachronistic concentration in modern Moscow Oblast, St. Petersburg, and Tatarstan.
Siberia/Asiatic Russia also appears relatively devoid of native populations. |
HIGH | |
| United States (Amerindigenous) | 10000BC-1870AD | Modern state borders appear visible due to strict border gridding used by HYDE, potentially from modern Populstat administrative boundaries. | LOW | |
| Witwatersrand-Johannesburg, South Africa | 10000BC-1880AD |
Known to have had a relatively high Neolithic population, but is almost certainly nonsensically concentrated relative to the rest of South Africa prior to the Witwatersrand Gold Rush of 1886.
Severity generally decreases between 1850-1880AD, but should still be inspected. |
LOW |
