Atlas Handbook
Layer catalogue
One record per documented layer: what it claims, what it rests on, and how much of it was drawn rather than found.
-
Antarctic expedition tracks
A planned crossing, a voyage under sail and a drift with the ice are three different things, and the line tells you which.
-
Antarctic observations and fixes
Nineteen dated positions from Cook to the loss of Endurance, sized by how well each one is actually known.
-
Dacia name attestations (research tier)
The full CND 1.0 release candidate, including silences and normalized imports - compiled, filterable, and cleared by nobody. Not citable as established evidence.
-
Dacia name attestations (reviewed)
Where a source does or does not name a place in the Dacia corpus - carrying only records a human has cleared, which is why it is currently empty.
-
Depicted extents
One footprint per map in the corpus - what each map shows, which is a claim about the map and not about the ground.
-
Fourth Crusade, diversion and assaults
Three events at two places. An event is not a territory, and the position is the place, not the state.
-
Fourth Crusade, the routes travelled
Two generalisations between ports, because no source in this corpus gives a track.
-
Ghost geographies
Fifteen features that were claimed, mapped and later rejected, five of them by a seventeenth-century cartographer in his own voice. The layer is empty, and this page explains why that is the correct state.
-
Hanseatic institutional events
Privileges, ordinances, embargoes, conflict, treaties, Hansetage and Kontor closures - the League's history as acts at named places.
-
Hanseatic places and participation phases
Sixty source-linked city, market and Kontor phases with historical and modern names, and an explicit class for what each place's participation actually was.
-
Hanseatic trade corridors
Seven maritime, riverine, overland and mixed corridors whose line width states how well attested each one is.
-
Josephinian survey: sheet index
Where the First Military Survey of Transylvania covers the corpus. No scan is served from here, and the footprints are reconstructed rather than taken from the archive index.
-
Matthew Paris itinerary, stage by stage
Fourteen stages of a drawn road, shown at modern positions the manuscript never gives.
-
Modern national boundaries
Present-day borders, offered as a reading grid over historical material and never as evidence about it.
-
Natural Earth coastline
Small-scale physical coastline, the neutral base the historical layers are drawn over.
-
Natural Earth land outline
Coastal landmass outlines, a subtle physical frame for the corpus.
-
Natural Earth rivers
Major river and lake centrelines - the waterways that carried maps and trade.
-
Principalities and provinces, 1526-1859
Wallachia, Moldavia and Transylvania as dated phases rather than one timeless outline - and the rings are editorial envelopes, not delimitations.
-
Roman Dacia: principal sites
Legionary fortresses, road stations and mining centres of the province - every point the corpus's own reference position, and none an excavated centroid.
-
Roman Dacia: roads and frontier corridors
The province as a network - roads joined through attested stations, and limes corridors this project drew. The dashes say which is which.
-
Roman Empire, AD 117
The empire at its greatest recorded reach, drawn as a modern reconstruction of a frontier the Romans did not draw as a line.
-
Terra Australis, the conjectured south
An envelope, not a coastline. It marks where maps drew a southern continent, and refuses to say what shape they gave it.
-
The Holy Land as a network, the ports
Four ports out of twelve Holy Land records. The other eight say what happened at Jerusalem or what it meant, and neither has a coordinate.
-
Treaty frontiers, 1829-1947
What each settlement moved, drawn as dated phases - and every line editorial, because not one instrument in the ledger supplies geometry this project could use.
-
Venetian galley routes (mude), c.1200-1500
The documented convoy lines and private trades, routed through their staging ports - relations between harbours, not tracks across water.
-
Venetian maritime ports, c.1200-1500
The nodes of the stato da màr, each phase a separate feature - and a trading quarter is never drawn as a colony.
-
Venetian possessions, c.1200-1500
Territorial extent of the stato da màr as phased fills clipped to the coastline - the layer most easily mistaken for sovereignty, and the one that claims least.
