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":
{{Location map|Germany Neckar |...}}{{Location map many|Germany Neckar |...}}{{Location map+|Germany Neckar |...}}{{Location map~|Germany Neckar |...}}
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
}}
