Template:BC Basemap
Parameters:
- lat: lattitude of the center of the map (default:50.00)
- long: longitude of the center of the map (default:123.00}
- height: height of the map in km (default:10km)
- width: width of the map in km (default:10km)
- scale: map scale in pixels / km (default:100 pixels/km)
- link: text to appear in the link
calculation notes
- 1 nautical mile = 1.85200
- 1 degree lattitude = 60 nautical miles = 111.12km
- 1 degree longitude = 111.12km * cos (lattitude)
- 0.6427 = cosine (50). This is required to adjust the longitude scale since the real world distance for one degree of longitude is proportional to the cosine of the lattitude. Ideally this would be a call to a cosine function but I don't think the wiki can do that so I've pre-programmed it to 50 degrees lattitude for now.
