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
}}
