Module:Location map/data/Germany Weser is a location map definition used to overlay markers and labels on an equirectangular projection map of Weser. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.

Usage

These definitions are used by the following templates when invoked with parameter "Germany Weser":

Map definition

  • name = Weser
    Name used in the default map caption
  • x = (100*( ($2 - (12.05 + 8.0)/2)*((1 - 0.91)*($1 - 54.02)/(50.0 - 54.02) + 0.91) + (12.05 + 8.0)/2 - 8.0)/(12.05 - 8.0))
    An expression to calculate a location on the map via its longitude; evaluates as 0 along the left edge and 100 along the right edge
  • y = (100*($1 - 54.02)/(50.0 - 54.02))
    An expression to calculate a location on the map via its latitude; evaluates as 0 along the top edge and 100 along the bottom edge


Examples using location map templates

Bremen is located in Weser
Bremen
Bremen
class=notpageimage|
Show "Bremen" on map

Example labeling "Bremen": 

{{Location map
| Germany Weser
| label = Bremen
| label_size = 90  <--percent 0-900%
| caption = Show "Bremen" on map
| lat=53.075
| long=8.8071
| background = #FFFF99
| float = right
| width = 250
}}
Bad Hersfeld is located in Weser
Bad Hersfeld
Bad Hersfeld
class=notpageimage|
Show "Bad Hersfeld" on map

Example for orange "Bad Hersfeld" at bottom: 

{{Location map
| Germany Weser
| label=Bad Hersfeld  | position=left
| label_size = 90  <--percent 0-900%
| caption = Show "Bad Hersfeld" on map
| lat=50.8689 | long=9.7072
| background = <!--orange-->#FFCC66
| float = right
| width = 220
| AlternativeMap = <!--none(default)-->
}}

Two examples, showing "Fulda" & "Bremerhaven" with map position aligned (by using parameters "float=left" and "float=right"). Note that the marker for "Bremerhaven" is west of the mark, due to narrow longitudes far north (on non-equirectangular map).

Fulda is located in Weser
Fulda
Fulda
class=notpageimage|
Show "Fulda" on map
Bremerhaven is located in Weser
Bremerhaven
Bremerhaven
class=notpageimage|
Show "Bremerhaven"

Longitude lines converge to the center, so center towns would be positioned more accurately. The "polar" skew factor is used to scale longitude smaller near polar latitudes (relative to map height), and position longitudes from map center, rather than left-side base longitude.

Multiple markers on the same map

Example showing "Bremerhaven" (and "Wolfsburg") on one map.
