Map service options

On the Details pane for Map charts, you can select the map service to use for providing map images.

Configuring map service options

Stop the IBM® SPSS® Modeler Server.
If you're going to apply local geojson formatted map files, put them in the directory <Modeler_installation_directory>/dataview/conf/public/mapfiles. If the directory doesn’t exist, create it.

Open the file <Modeler_installation_directory>/dataview/conf/application.conf in a text editor and add the following options to the map.resources section. In this example, two new maps named World - Local Map and

World - Online
Map

are added.

map.resources {
  "mapservices" :
    [

      {
        "type"      : "geojson",
        "name"      : "World (Bulit-in)",
        "location"  : "built_in_world",
        "id"        : "built_in_world"
      },
      {
        "type"      : "geojson",
        "name"      : "Blank (Built-in)",
        "location"  : "built_in_blank",
        "id"        : "built_in_blank"
      },
      {
        "type"      : "geojson",
        "name"      : "World - Local Map",
        "location"  : "/mapfiles/world.json",
        "useProxy"  : "false",
        "id"        : "world_local"
      },
      {
        "type"      : "geojson",
        "name"      : "World - Online Map",
        "location"  : "http://map.example.com/map/world.json",
        "useProxy"  : "true",
        "id"        : "world_online"
      }    ]
}

The following parameters are available for the map options:

Table 1. Map service parameters
Option	Value	Type	Required?	Description
`type`	`geojson`	String	Yes	Currently, only the value `geojson` is supported for this option.
`name`	Map name	String	Yes	Enter a name for the map. This name is shown in the Map service drop-down on the Details pane for map charts.
`location`	Map location	String	Yes	Enter the URL or local file location of the map. For URL, it must begin with `http://` or `https://`. For local file, it must begin with the path /mapfiles/.
`useProxy`	`true` or `false`	String	Yes	Use `true` if the map location is a URL. Use `false` if the map location is a local file.
`id`	Map ID	String	Yes	Use an unique ID for each map.

Note:

Don't remove the default World (Built-in) and Blank (Built-in) options.
Remember to use a comma between the content blocks as shown in the example, and be sure your new map.resources section is valid JSON formatted content.
The IBM SPSS Modeler Server (or the standalone SPSS Modeler Client without Server) must be able to access the map location.

Start the IBM SPSS Modeler Server.

Now while working with map charts, on the Details pane, you'll see the new map service you added.
