How Champography calculates the point
Published dataset 1.8 · wgs84-frechet-v1
Every coordinate shown above is calculated offline, validated, and published in a content-hashed static artifact. The browser reads stored results; it does not approximate historical epicenters while you move the slider.
The epicenter
The equal-season-weight geodesic Frechet mean of the selected champion season points, computed on the WGS84 ellipsoid. Each point is the champion's verified home rink for the season they won, not a later arena the franchise moved into.
Season weighting
Every championship season contributes a total weight of exactly 1.0. The Stanley Cup has one winner per season, so no season splits its vote.
Retroactive selections
Not applicable: no season has produced co-champions. From 1918 through 1926 the Cup was contested between the NHL champion and champions of rival western leagues, so a non-NHL club could win it; the 1925 Victoria Cougars did, and that title is counted because the Stanley Cup, not the NHL playoff title, is what this dataset tracks. Each claim records whether the champion was an NHL member.
Historical arenas
The champion's regular-season home rink is used, never a neutral Final site. Season-specific arena chronology is applied throughout: the 1924 Canadiens point is the Mount Royal Arena rather than the Forum, which they did not occupy until 1926; Ottawa's four championships split between Dey's Arena and the Ottawa Auditorium; and the Rangers' first three titles resolve to Madison Square Garden III on Eighth Avenue rather than the present Garden. Several Finals were played away from the champion's rink, including the 1928 and 1940 Rangers when the circus occupied the Garden and the 2020 Lightning in the Edmonton bubble; those displacements are recorded in claim notes and do not move the season point.
The champion policy
The single Stanley Cup winner counts for every season the Cup was awarded. No selector reconciliation is required.
Seasons with no champion
Two seasons remain on the timeline carrying zero weight. The 1919 Final was abandoned tied during the Spanish flu epidemic, and the 2004-05 season was cancelled by a lockout; the Cup itself is engraved with both facts.

Place labels
A point inside a municipality is labelled with that municipality, decided by point-in-polygon against Census place boundaries rather than by proximity. GNIS stores a city as a single downtown point, so nearest-point resolution inside a large city found whichever neighbourhood, park or subdivision happened to sit closest, and a point in Lexington resolved to Hollywood, Kentucky. Where boundaries overlap the smallest containing place wins, as the most specific true answer. Outside every boundary the label names the nearest populated place in the official USGS GNIS extract, which includes small and unincorporated communities. GNIS also classes apartment blocks, public-housing projects and neighbourhood tracts as populated places, so where the nearest name is one the Census Bureau does not list, a Census-recognized place in the same state is preferred when it lies within twice the distance or three kilometres further; rural communities the Census Bureau also omits keep their own name rather than being replaced by a larger town miles away. Places GNIS marks as no longer existing are not published while any extant place lies within fifteen miles. GNIS covers the United States only, so a source-controlled Canadian table of 418 populated places supplies Canadian labels, compiled rather than read from an authoritative extract and accurate to about a kilometre. A county is stated only when the nearest place is within 15 km, since the county belongs to the place rather than to the point, and beyond 25 miles a label gives distance and bearing instead of saying 'near'. Boundary geometry is simplified to roughly 220 m, far below the size of any municipality.
Current verified coverage: Champion coverage spans 1917-18, the NHL's first season and the first Stanley Cup won by an NHL club, through the latest completed season. The 1925 Victoria Cougars are counted as the last non-NHL Cup winner. Three championship franchises are defunct rather than ancestral to current clubs: the original Ottawa Senators, who moved to St. Louis in 1934 and folded in 1935 and are unrelated to the 1992 expansion Senators, the Montreal Maroons, and the Victoria Cougars. Demolished rinks carry documented historical-site coordinates with their precision stated in the public CSV.
