-- This module creates framed maps of anywhere in the world, at the required scale, and enables annotations, 
-- dots, shapes, lines and other ways to customise the area of the map being shown. It also provides a link
-- to an interactive fullscreen version, which has locator dots instead of annotations and shapes.


-- This is the 2025 successor module to a wiki-markup template version of 2024, which itself was a successor 
-- to the 'Graph'/VEGA driven template that was begun in 2016, until the Vega version was switched off in 2023.

-- This module is called from template {{OSM Location map}}, which uses the same parameter formats as before.

-- In addition it may at some point be possible to use a more concise parameter format using the template {{OSM Location dots}}
-- In general the css output from the two formats will be identical, but the the concise version will allow bits of
-- greater control over some of the settings.

-- see the documentation on the two template pages for details of how to use the mapping features.

-- If language customisation is needed, there are text items below that can be translated. Also see the color table
-- below with details of how to add additional color names to allow localised alternatives.
-- (Translating other language shape-types could be possible, but has not currently been contemplated. 
-- Parameter name translation would be harder but likely to be possible, ideally still retaining compatibility 
-- with template calls already written using English).

-- -------------- the following text variables are used within the template, and can be translated as required ---------------
-- -------------- you may wish to retain the English version as a comment, to keep track of the original phrase --------------

width and height are the size, in pixels, of the map, which will be centerd around lonbase,latbase.
Method: Convert lon and lonbase to meter-offsets from coord(0,0), and subtract lonbase from lon,
zoom and latbase are used to scale the resulting meter-offset to pixels, and add it to width/2.
Convert lat and lat-base to meter-offsets from coord(0,0), subtract lat from latbase,
scale the resulting meter-offset to pixels, add it to height/2.
A correction factor '*(1-(0.075*(math.abs(t.latbase)/90) ) )' compensates for an error that seems to creep in towards 
the edges of the map at higher latitudes. It was identified experimentally, and ensures a dot at the edge is 
in the same place as if that location is positioned at the centre.
