NNM Map Viewer


Simple map functionality with capabilities of showing markers and lines.


The map is created from parameters defined in the URL.

Mandatory parameters

The map is initially centered at coordinates defined by the origo parameter. Example: origo=69.00,19.00.
The map has an initial zoom level.

Optional parameters

A title can be defined. Example: title=My%20own%20special%20title.
point is an array of coordinates for which a polygon should be drawn between each consecutive point (order is therefore important). A polygon can be shown between (at least two) coordinates defined with the point parameter. Each point is defined by latitude and longitude values. Example: point=-1,2&point=-2,-1&point=1,-2&point=2,1.
A marker can be shown for origo (showMarkerForOrigo=true).
marker is an array of coordinates where a marker should be placed. Markers can be shown for (one of several) defined points. Example: marker=6.90,7.23 or marker=6.90,7.23&marker=69.2203,17.1234.
