The map type contains all the information necessary to display a map on the screen. The map type is opaque, so use the functions in this module to maniuplate the map.

Set the tile server.

The format is a URL with {x} {y} {z} placeholders for the x, y and zoom coordinates.

Set the width, as displayed on the screen, of a given Map.

Set the height, as displayed on the screen, of a given Map.

Set the width/height in px of a tile. Note, this is dependent on the tile server, and the default of 256px is almost always correct.

Move the map a given number of pixels in the x and y dimensions.

For example, up 10px and right 10px:

map
|> move { x = 10, y = -10 }

Move the center of the map to a specific location.

For example, move the map to Shanghai:

map
|> moveTo (Maps.Geo.LatLng 31.267401 121.522179)

Sets the zoom to a specific level

For example, zoom all the way out

map
|> zoom 0

Or all the way in:

map
|> zoom 19

Zoom into the center of the map.

For example zoom out two levels:

map
|> zoom -2

Zoom into an x,y co-ordinate on the map.

For example, zoom into the top left corner of the map:

map
|> zoom 1 { x = 0, y = 0}

Move and zoom the map to cover given the bounds.

For example, view the bounds of Madagascar:

let
  madagascar =
    Maps.Geo.bounds
      { northEast = Maps.Geo.latLng -11.9519639 50.48377989999999
      , southWest = Maps.Geo.latLng -25.6065157 43.1851395
      }
in
  map
  |> viewBounds madagascar
