Stanley Cup Champions Since 1915

Stanley Cup Champions Since 1915:

Average Location of Stanley Cup Champions Since 1915:

The average locations were created using a window function in PostgreSQL. We can utilise the geography type to take into account the curvature of the earth and make the calculation on a spheroid.

So for the average location of the last five years:

select id,
ST_Centroid(st_collect(geom)
over (ORDER BY id ROWS BETWEEN 4 PRECEDING AND CURRENT ROW)::geography,
True)::geometry as five_year_cent
from nhl.winner_1915

QGIS OpenStreetMap Scales

Save as a text file ending in .xml like qgis_scales.xml

These are the scales OpenStreetMap tiles are rendered in for 96 dpi, so the map will look sharp on most monitors. These are the scales for the zoom levels.

The xml file can then be loaded into the project from:

Project> Project Properties…> General> Project scales
