A Note on Accuracy

This map anchors landmarks to real latitude and longitude wherever reliable coordinates can be resolved.

Landmark points are resolved from the project’s existing historical records, primarily through linked Wikipedia entries and manual fallback overrides for known stable sites. Zoom, pan, and spatial relationships are therefore real-world rather than purely illustrative.

What is not yet fully digitized are the larger historical geometries: road centerlines, settlement extents, tanks, wetlands, canal systems, and land parcels by decade. Those still need proper georeferencing and tracing from survey maps.

Creating the Map

Part research ledger, part stubborn illustration problem, part browser diplomacy.

The current map begins with decade-wise place records, old map references, and a frankly unreasonable amount of nudging. Each landmark is matched to a modern coordinate, checked against the historical references.

The base geography is rendered separately from the editorial styling, which is a polite way of saying the map has one foot in archival method and the other in theatrical set design. That split is intentional. It means the project can keep getting more accurate without becoming visually dull.

The long game is to make the whole thing extensible: more traced roads, better river geometry, settlement edges, wetlands, shifting transport corridors, and cleaner provenance for every point. This was always meant to be a marauders map, usable fun and meant for mischief. Even with every possible historical detail added it will always be a tool that is fun!
