Indicacións de uso do modelo

Uso[editar a fonte]

Obxectivo: Mostra unha imaxe dun mapa (tirada de OpenMaps), con imaxes ou iconas enriba dela, especificadas polo usuario, utilizando coordenadas de latitude e lonxitude, ou tirando datos de Wikidata.

Parámetros do modelo[Editar os datos do modelo]
Parámetro		Descrición	Tipo	Estado
data	`1`	Comma separated list of JSON objects that describing what data to draw on the map	Cadea de caracteres	recomendado
width	`width`	Total width of the graph	Número	opcional
height	`height`	Total height of the graph Por defecto Half of the width	Número	opcional
padding	`padding`	sen descrición	Número	opcional
lat	`lat`	Latitude do centro do mapa	Número	opcional
lon	`lon`	Lonxitude do centro do mapa	Número	opcional
zoom	`zoom`	Nivel de zoom do mapa (0..18)	Número	opcional
wdqs	`wdqs`	An optional Wikidata query to use instead of the data - the query would generate a list of items just like data, but it must contain a "coord" field with the location	Cadea de caracteres	opcional
colorScaleField	`colorScaleField`	If given, this data field will be used to make dots of different color, one color per unique value of this field	Cadea de caracteres	opcional
minimap	`minimap`	If set, 0 or false will always hide the map, and 1 or true will always show it. Make sure the map is big enough include the minimap. By default, the map will be shown for zoom levels 5+ if the map is sufficiently large	Lóxico (booleano)	opcional

Mostrar volcáns, tirando os datos de Wikidata
O resultado da consulta debe ter as mesmas columnas (campos) como nos outros exemplos (texto, imaxe, ...)

{{Graph:Street map with marks | width=800 | height=400 | lat=42 | lon=-8 | zoom=1 | colorScaleField=type | wdqs=
SELECT (SAMPLE(?coord) as ?coord) (SAMPLE(?type) as ?type)
WHERE {
  ?item wdt:P625 ?coord .
  ?item wdt:P31 wd:Q8072 .
}
GROUP BY ?item
}}
