Help:Extension:Kartographer/it

L'estensione Kartographer crea mappe interattive su wiki di Wikimedia. Questa pagina mostra tecniche per creare mappe dinamiche utilizzando i tag di Kartographer, che include mappe in pagine wiki, e , che crea collegamenti a mappe dinamiche.

Per iniziare
 Questo codice inserirà una semplice mappa interattiva (come quella mostrata a destra), con la possibilità di massimizzarla o con un doppio click sulla mappa o con un click sull'icona nell'angolo a destra.


 * On Wikivoyage and test2wiki, this embedded map is interactive. A single-click is used to pan the map; double-clicking (or clicking the icon in the right corner) opens a full-screen map, which is also interactive.
 * On Wikipedia and other Wikimedia wikis, this embedded maps is static. Single-clicking opens a full-screen map, which is interactive.

Il parametro  prevale sull'allineamento standard e permette di scegliere tra sinistra, destra o centro. L'attributo  permette di avere livelli di ingrandimento tra 0 e 19. Zero è quello più esteso, 19 è quello più ravvicinato.

Uso di
 { "type": "Feature", "geometry": { "type": "Point", "coordinates": [-122.3988, 37.8013] }, "properties": { "title": "Exploratorium", "description": "", "marker-symbol": "museum", "marker-size": "large", "marker-color": "0050d0" } }

Il contenuto del tag deve essere vuoto o essere un valido GeoJSON con styling, come prodotto da un editor GeoJSON. Kartographer supporta la specifica simplestyle con icone Maki (con licenza Creative Commons Zero). Help:Extension:Kartographer/Icons contiene un elenco completo delle icone supportate.

Frames
Frameless maps are good for insertion as part of a template, whereas framed maps are good for insertion directly into the page, either by hand or by using the visual editor.


 * To insert a map without a frame, add the "frameless" attribute:
 * To add a caption, use the  attribute.

If GeoJSON has more than one counter, the value of the first one will be shown as the link text. Optionally, editors may add a suffix to have multiple counters on the page at the same time. This way  will have different counter from.

It would make sense to use a distinct color for each counting group. All data added via will also be shown in all maps inserted with, unless the   attribute is used.

The attributes,  , and   control the location of the popup map. Use  for the text of the link (could be any valid wikitext markup). Use  to add the contents of this tag to the named group (see below).

Marcatori
I marcatori possono essere aggiunti a una mappa per indicare un luogo. Queste caratteristiche sono aggiunte tramite il formato JSON.

Risultato:

Markers can also contain information such as images and links to articles.

Result (interact with marker to see result):

Wikidata IDs for OSM data can be used to highlight borders using the geoshape service.

Risultato:

Wikidata IDs can be used to mask the entire map except a specified region.

Risultato:

Markers can be numbered.

Risultato:

Markers can use letters.

Risultato:

Add several map markers in different sizes using a feature collection.

Risultato:

Add groups of different colored map markers and different counters.

Risultato:


 * Map markers can use any color that has a RBG value (a quick internet search of "rgb color picker" will show several options).
 * Markers can be one of three different sizes: small, medium or large.
 * GeoJSON that is created elsewhere can be copied (in accordance with licensing and copyright restrictions) and then pasted into maplink (for example)
 * If you are creating maps on Wikivoyage, it might be a good idea to use Groups (see below).
 * If you want to learn more about adding external data to your map, see the External data section.

Gruppi
For use on the Wikivoyage project, there is a need to show a map whose data is defined somewhere else on the page. For example, there may be multiple points of interest (POI) defined with tags, and one common map on the side of the page that shows them all.

The grouping concept allows editors to share data between multiple and  tags.

By default, the data inside the or  tag is shown only for that one tag, and will not be shown anywhere else.

If or  specify the   attribute, the data inside those tags will be placed into a named group, together with all the other data by the same group name. As a result, any tags with the same group name will show the same map data, and each tag may incrementally add data to the group.

A tag may also show other groups, regardless if it belongs to a group or not, by specifying the  attribute. Comma-separated multiple group names may be specified. The group name may only contain lower case English letters. This matrix shows what data will be shown for each tag.

Dati esterni
 { "type": "ExternalData", "service": "geoshape", "ids": "Q797" }

In addition to drawing polygons using GeoJSON, you may also get outlines of the well known geographical objects by their Wikidata ID if they are marked as such in the OpenStreetMap database. For example, the Wikidata item for Alaska is Q797, and we can draw it on a map by using the "external data" reference. More than one ID may be specified separated by a comma. To create a mask over the areas of interest, use the "geoshape" service. To invert this and create a mask over everything else, use the "geomask" service.

GeoShapes via Wikidata Query
 { "type": "ExternalData", "service": "geoshape", "query": "SELECT ?id ?head (SAMPLE(?img) as ?img_) (min(?partyId) as ?party) (if(?party = '0', '#800000', if(?party = '1', '#000080', '#008000')) as ?fill) (concat(, ?headLabel, ) as ?title) (concat(?stateLabel, '\\n', '') as ?description) WHERE { ?id wdt:P31 wd:Q35657 . ?id wdt:P6 ?head . ?head wdt:P102 ?party . BIND(if(?party = wd:Q29468, '0', if(?party = wd:Q29552, '1', '2')) as ?partyId) SERVICE wikibase:label { bd:serviceParam wikibase:language 'en' . ?head rdfs:label ?headLabel . ?id rdfs:label ?stateLabel . } OPTIONAL { ?head wdt:P18 ?img . } ?link schema:about ?head . ?link schema:isPartOf  .} GROUP BY ?id ?head ?headLabel ?link ?stateLabel" }

While this helps with the simple use cases when the Wikidata ID is well known, sometimes you may want to get a list of IDs as a result of a Wikidata query. A SPARQL query gets a list of all US states in the ID column of the result, and geoshapes service adds the geometrical outlines for each state. All other columns in the SPARQL query result become values in the "properties" object. The "fill" column changes the color of the state. The "title" column shows state governor's name, and "description" has wiki markup to show the state name and the governor's picture. To edit this query, copy the query parameter after the "#" symbol at ''' https://query.wikidata.org/#... ''':

Dati cartografici tramite Commons

 * Ulteriori informazioni: 

Map data stored on Commons can be drawn on the map. For example, c:Data:Neighbourhoods/New York City.map:

 { "type": "ExternalData", "service": "page", "title": "Neighbourhoods/New York City.map" }

Combining multiple data types
 [ {    "type": "ExternalData", "service": "geoshape", "ids": "Q13518258", "properties": { "stroke": "#ffb100", "stroke-width": 6, } },  {    "type": "Feature", "geometry": { "type": "Point", "coordinates": [4.75566, 44.104498] }, "properties": { "title": "Porte de Castellan" } },  {    "type": "Feature", "geometry": { "type": "Point", "coordinates": [4.75829, 44.10258] }, "properties": { "title": "Porte Léon Roche" } } ]

You can combine ExternalData, Feature, and FeatureCollection together in the same &lt;mapframe> or &lt;maplink> element:

 [ {    "type": "ExternalData", "service": "page", "title": "Neighbourhoods/New York City.map" }, {    "type": "ExternalData", "service": "geoshape", "ids": "Q160409", "properties": { "fill": "#07c63e", "title": "Central Park" } },  {    "type": "Feature", "properties": {"title": "Roosevelt Island", "marker-color": "f01080"}, "geometry": { "type": "Point", "coordinates": [ -73.94511222839355,       40.76734665426719      ]    }  } ]

Map data from Commons can be combined with other types of data:

Stile per elementi Wikidata
 { "type": "ExternalData", "service": "geoline", "ids": "Q2108", "properties": { "title": "Highway I-696", "description": "", "stroke": "#ffb100", "stroke-width": 8 } }

For external data, you can also add styles and titles, using the properties keyword:

The main style keys are: "stroke" (color), "stroke-width", "stroke-opacity", "fill" (color), "fill-opacity".

Overlapping elements
Map elements that overlap are drawn in the order in which they are written in the code. For instance, if a map includes two lines that overlap, the line that is defined first will appear beneath the line that is defined second. The following examples show how this can affect the appearance of the map:

 { "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": {"fill": "#ff0000","fill-opacity": 0.7,"stroke-width": 0}, "geometry": { "type": "Polygon", "coordinates": [ [ [ 77.926025390625, -25.150257104114733 ], [ 80.14251708984374, -25.150257104114733 ], [ 80.14251708984374, -24.43714786161562 ], [ 77.926025390625, -24.43714786161562 ], [ 77.926025390625, -25.150257104114733 ] ] ] } }, { "type": "Feature", "properties": {"stroke": "#fffa00","stroke-width": 5}, "geometry": { "type": "LineString", "coordinates": [ [ 77.926025390625, -25.150257104114733 ], [ 80.14251708984374, -24.43714786161562 ] ] } }, { "type": "Feature", "properties": {"stroke": "#000000","stroke-width": 5}, "geometry": { "type": "LineString", "coordinates": [ [ 77.926025390625, -24.43714786161562 ], [ 80.14251708984374, -25.150257104114733 ] ] } } ] }

The code for the map above includes three elements, all of which use GeoJSON's "feature" functionality. The first feature is a "Polygon" - the red rectangle. This is followed by two "LineString" features. The yellow line is defined first, so it appears beneath the black line. Note that the hierarchy used to draw elements applies regardless of whether the data is raw GeoJSON or comes from a Wikidata ID or Commons data page.

The map below changes the order from that of the first example: the black line is defined first and is thus moved to the bottom of the stack:

 { "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": {"stroke": "#000000","stroke-width": 5}, "geometry": { "type": "LineString", "coordinates": [ [ 77.926025390625, -24.43714786161562 ], [ 80.14251708984374, -25.150257104114733 ] ] } }, { "type": "Feature", "properties": {"fill": "#ff0000","fill-opacity": 0.7,"stroke-width": 0}, "geometry": { "type": "Polygon", "coordinates": [ [ [  77.926025390625,  -25.150257104114733  ],  [  80.14251708984374,  -25.150257104114733  ],  [  80.14251708984374,  -24.43714786161562  ],  [  77.926025390625,  -24.43714786161562  ],  [  77.926025390625,  -25.150257104114733  ]  ]  ]  } }, { "type": "Feature", "properties": {"stroke": "#fffa00","stroke-width": 5}, "geometry": { "type": "LineString", "coordinates": [ [ 77.926025390625, -25.150257104114733 ], [ 80.14251708984374, -24.43714786161562 ] ] } } ] }

Rendering options
The following table shows how a map can be formatted for display on a wiki page. The table contains two columns: the first shows an interactive map via the tag, and the second showing the rendering of an example image with the same options.

Lingue della mappa
Le etichette della mappa cercheranno di usare la lingua del wiki in cui è mostrata la mappa. Se tale lingua non è disponibile, la mappa mostrerà un lingua di ripiego come descritto.


 * 1) Ricerca del valore nella lingua richiesta
 * 2) Ricerca del valore in una lingua (o lingue) che siano indicate come lingue di ripiego
 * 3) Ricerca di un valore traslitterato
 * 4) Ricerca per l'etichetta nella lingua locale
 * 5) Se non è trovato alcun valore, non viene mostrata l'etichetta

You can specify the language to use for labels by adding the  followed by the desired language code. e.g. lang="ja" to display labels in Japanese (if available).

Result:. This shows map labels in the languages of the area mapped (essentially opting out of internationalization). This post gives more guidance about when, and why, you might wish to user lang="local"—and generally explains how OpenStreetMap multilingual data works.

Without the  attribute, maps will display in the language of the wiki in which they appear.

Ripiego per la lingua della mappa
Inizialmente queste indicazioni di ripiego seguono quelli di MediaWiki. Le indicazioni di ripiego linguistico per le mappe sono conservati in fallbacks.json e possono essere diversi da quelli di Mediawiki. Singoli progetti Wikimedia possono [https://phabricator.wikimedia.org/maniphest/task/edit/form/1/?title=Request%20to%20change%20Maps%20fallback%20for%20XXXX%20Wiki&tags=Maps&description=Please%20provide%20a%20link%20to%20community%20consensus%20for%20this%20change.%0A%0AA%20description%20of%20the%20requested%20fallback%20is%20also%20needed. richiedere una modifica al processo di ripiego] in Phabricator. Altre informazioni tecniche si trovano in T192701.

Maps use map data, including map label data for all languages, from the open-source mapping project OpenStreetMap. If the map you want to display doesn’t offer labels in the desired language, you can add labels in that language by adding them to OpenStreetMap. To get you started, there is an OpenStreetMap Beginners’ Guide, and guidance about naming conventions.

A community can decide to change its language fallbacks
