Module:Location map/data/Germany Neckar is a location map definition used to overlay markers and labels on an equirectangular projection map of Neckar. 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 Neckar":

• Template:Tlx
• Template:Tlx
• Template:Tlx
• Template:Tlx

Map definition

• name = Neckar

  Name used in the default map caption

• image = Neckar_watershed_closer.gif

  The default map image, without "Image:" or "File:"

• x = (100*( ($2 - (9.67 + 8.0)/2)*((1 - 0.86)*($1 - 49.71)/(48.0 - 49.71) + 0.86) + (9.67 + 8.0)/2 - 8.0)/(9.67 - 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 - 49.71)/(48.0 - 49.71))

  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

Mannheim

The example on the left shows the correct placement of Mannheim when Germany Neckar is used with {{Location map}}.

Note that the marker for "Mannheim" is west of the mark, due to narrow longitudes far north (on non-equirectangular map). Longitude lines converge to the center, so center towns would be positioned more accurately. The "polar" skew factor should be used (as in Template:Location map) to scale longitude smaller near polar latitudes (relative to map height), and position longitudes from map center, rather than left-side base longitude (see example below).

{{Location map | Germany Neckar
 | width = 250 | float = right
 | caption = Example using ''Location map''
 | label = Mannheim | label_size = 90
 | background = #CCCC11 | position = bottom
 | lat_deg = 49.4890
 | lon_deg = 8.4691
 }}

Rottweil

The example shows the correct placement of Rottweil when Germany Neckar is used with {{Location map}}.

{{Location map | Germany Neckar
 | width = 250 | float = right
 | caption = Example using ''Location map''
 | label = Rottweil | label_size = 90
 | background = #FFCC66 | position = top
 | lat_deg = 48 | lat_min = 10 |lat_sec = 05
 | lon_deg = 08 | lon_min = 37 |lon_sec = 29
 }}

Multiple markers on one map

The example on the left shows the correct placement of locations when Germany Neckar is used with {{Location map}}.

{{Location map many | Germany Neckar
 | width = 250 | float = right
 | caption = Example using ''Location map many''
 | label = Mannheim | label_size = 100
   | bg = #CCCC11 | pos = bottom
   | lat_deg = 49.4890
   | lon_deg = 8.469
 | label2 = Rottweil | label2_size = 100
   | bg2 = #66BBDD | pos2 = top
   | lat2_deg = 48 | lat2_min = 10
   | lon2_deg = 08 | lon2_min = 37.5
 | label3 = Heilbronn | label3_size = 90
   | bg3 = #FFFF99 | pos3 = top
   | lat3_deg = 49 | lat3_min = 9
   | lon3_deg = 09 | lon3_min = 13
 }}
