A Research-Grade Cartographic Archive
Two thousand four hundred interactive campaign maps, hand-overlaid each quarter by open-source intelligence teams — from theater-wide operations down to the platoon-level advance across a single Norman bocage.
Featured Campaigns
Four entries from a library of 2,400. Each map is georeferenced, dated to the operational week, and accompanied by the source dispatches, order of battle, and the historians' notes that explain the next click.
Beach-by-beach landings through the bocage breakout, Falaise pocket, and the Seine crossing. Eight overlay layers including German 5th Panzer Army dispositions from the Bundesarchiv and Allied after-action overlays from the U.S. Army CGSC.
Soviet envelopment on 19 November 1942 through the Paulus surrender on 2 February 1943. Cross-referenced to the Central Archives of the Russian Federation's holdings, with German and Russian perspective layers available side-by-side.
Thirty-one named operations across the Solomons, Marshalls, Marianas, Palaus, and the Ryukyu arc. Naval movement tracks drawn from the U.S. Naval History and Heritage Command submarine patrol reports.
Montgomery's defensive line through the 1,000-mile pursuit across Libya, ending with the surrender of the Afrika Korps. Includes Italian and Free French fronts and the Malta convoy overlay that made the campaign possible.
The Quarterly Refresh
Every map in the atlas is checked, refreshed, and re-issued on a fixed quarterly cycle. Each new overlay carries a provenance card naming the contributing archive, the OSINT team that drew it, and the date of the source materials.
Step 01
Each quarter our seven OSINT partners — including the Imperial War Museum's digital mapping unit and the National Archives' Cartographic Branch — provide fresh georeferenced inputs from their holdings. Sources are logged with accession numbers and publication rights.
Step 02
Our team of seven cartographers reconciles the new material against the existing map — adjusting unit positions to within 200 meters of historical record, normalizing symbology across theaters, and writing the layer's editorial summary for the researcher who will use it next.
Step 03
Every overlay ships with its provenance card visible on the map page: source archive, contributing OSINT team, accession references, the date the layer was drawn, and the average document upload turnaround — currently nine days from acquisition to fully OCR-verified transcription.

For Researchers & Educators
A condensed answer set for the working researcher, the wargamer, and the classroom educator. Long-form documentation is shipped with every premium subscription.
Every map carries a permanent citation slug (e.g. WW2T/MAP-0217/Q4-2025) that resolves to the underlying provenance record — contributing archive, accession number, and the cartographer responsible for the layer. Subscribers receive a printable citation block in Chicago, MHRA, and APA formats on the export panel.
Premium subscribers can export any map view as a print-ready PDF (300 dpi, CMYK with crop marks), a GeoTIFF (with the georeferencing metadata embedded), and a CSV of unit positions per day. The free tier offers low-resolution PNG exports for classroom use.
All overlays are drawn against the WGS 84 datum (EPSG:4326), with Web Mercator (EPSG:3857) tiling for fast in-browser display. Underlying source maps are warped to the modern coastline at an average residual of 240 meters — the figure is recorded on each map's provenance card.
Educators on accredited programs can request a 30-seat classroom license that includes a downloadable offline viewer and bulk PDF export. Researchers working in low-connectivity field archives can request a per-map offline bundle (map + overlays + provenance) from the member console.
