Application configuration

The application will load by default it will load the localConfig.json which is now stored in the configs\ folder

You can load a custom configuration by passing the localConfig argument in query string:

localhost:8081/?localConfig=myConfig#/viewer/openlayers/0

The localConfig file contains the main information about URLs to load and plugins to load in the various modes.

This is the main structure:

{
  // URL of geoStore
  "geoStoreUrl": "rest/geostore/",
  // printURL the url of the print service, if any
  "printUrl": "/geoserver-test/pdf/info.json",
  // a string or an object for the proxy URL.
  "proxyUrl": {
    // if it is an object, the url entry holds the url to the proxy
    "url": "/MapStore2/proxy/?url=",
    // useCORS array contains a list of services that support CORS and so do not need a proxy
    "useCORS": ["http://nominatim.openstreetmap.org", "https://nominatim.openstreetmap.org"]
  },
  // JSON file where uploaded extensions are configured

      // plugins to load for the embedded mode
      "embedded": [...]
      // plugins to load for the myMode mode
      "myMode": [...]
  }
}

If you are building your own app, you can choose to create your custom modes or force one of them by passing the mode parameter in the query string.

For configuring plugins, see the Configuring Plugins Section and the plugin reference page

Explanation of some config properties

  • loadAfterTheme is a flag that allows to load mapstore.js after the theme which can be versioned or not(default.css). default is false
  • initialState is an object that will initialize the state with some default values and this WILL OVERRIDE the initialState imposed by plugins & reducers.
  • projectionDefs is an array of objects that contain definitions for Coordinate Reference Systems

initialState configuration

It can contain:

  1. a defaultState valid for every mode
  2. a piece of state for each mode (mobile, desktop, embedded)

Catalog Tool configuration

Inside defaultState you can set default catalog services adding the following key

"catalog": {
  "default": {
    "newService": {
      "url": "",
      "type": "wms",
      "title": "",
      "isNew": true,
      "editable": true,
      "autoload": false
    },
    "selectedService": "Demo CSW Service",
    "services": {
      "Demo CSW Service": {
        "url": "https://demo.geo-solutions.it/geoserver/csw",
        "type": "csw",
        "title": "A title for Demo CSW Service",
        "autoload": true
      },
      "Demo WMS Service": {
        "url": "https://demo.geo-solutions.it/geoserver/wms",
        "layerOptions": {
          "tileSize": 512
          },
          "format": "image/png8"
        "type": "wms",
        "title": "A title for Demo WMS Service",
        "autoload": false
      },
      "Demo WMTS Service": {
        "url": "https://demo.geo-solutions.it/geoserver/gwc/service/wmts",
        "type": "wmts",
        "title": "A title for Demo WMTS Service",
        "autoload": false
      }
    }
  }
}

Set selectedService value to one of the ID of the services object ("Demo CSW Service" for example).
This will become the default service opened and used in the catalog panel.
For each service set the key of the service as the ID.

"ID_CATALOG_SERVICE": {
  "url": "the url pointing to the catalog web service",
  "type": "the type of webservice used. (this need to be consistent with the web service pointed by the url)",
  "title": "the label used for recognizing the catalog service",
  "autoload": "if true, when selected or when catalog panel is opened it will trigger an automatic search of the layers. if false, search must be manually performed."
  "readOnly": "if true, makes the service not editable from catalog plugin"
  "titleMsgId": "optional, string used to localize the title of the service, the string must be present in translations",
  "format": "image/png8" // the image format to use by default for layers coming from this catalog (or tiles).
  "layerOptions": { // optional
      "format": "image/png8", // image format needs to be configured also inside layerOptions
      "serverType": "geoserver or no-vendor, depending on this some geoserver vendor extensions will be used for WMS requests.",
      "tileSize": 512 // determine the default tile size for the catalog, valid for WMS and CSW catalogs
  },
  "filter": { // applicable only for CSW service
      "staticFilter": "filter is always applied, even when search text is NOT PRESENT",
      "dynamicFilter": "filter is used when search text is PRESENT and is applied in `AND` with staticFilter. The template is used with ${searchText} placeholder to append search string"
  },
  "fetchMetadata": true, // "if true, the metadata is fetched for the service, applicable only for COG service
  "records": [{ // array of the COG layers of the service, applicable only for COG service
    "sourceMetadata": "metadata of the COG layer",
    "bbox": "bbox formulated for the COG layer",
    "url": "the url pointing to the COG layer data"
  }]
}

CSW service
filter - For both static and dynamic filter, input only xml element contained within (i.e. Do not enclose the filter value in )

Example:

{
    "filter": { // Default filter values
        "staticFilter": "<ogc:Or><ogc:PropertyIsEqualTo><ogc:PropertyName>dc:type</ogc:PropertyName><ogc:Literal>dataset</ogc:Literal></ogc:PropertyIsEqualTo><ogc:PropertyIsEqualTo><ogc:PropertyName>dc:type</ogc:PropertyName><ogc:Literal>http://purl.org/dc/dcmitype/Dataset</ogc:Literal></ogc:PropertyIsEqualTo></ogc:Or>",
        "dynamicFilter": "<ogc:PropertyIsLike wildCard='%' singleChar='_' escapeChar='\\'><ogc:PropertyName>csw:AnyText</ogc:PropertyName><ogc:Literal>%${searchText}%</ogc:Literal></ogc:PropertyIsLike>"
    }
}

COG service
fetchMetadata - By default, the metadata is fetched on saving the COG service for each layer (url) configured

records - Records of the COG layer

Example:

{
    "fetchMetadata": true,
    "records": [{
        "url": "https://example.tif",
        "sourceMetadata": {
            "crs": "EPSG:32632",
            "extent": [463560, 5758030, 469410, 5767210],
            "height": 900,
            "width": 500,
            "tileWidth": 256,
            "tileHeight": 256,
            "origin": [463560, 5767210, 0],
            "resolution": [10, -10, 0]
        },
        "bbox": {
            "crs": "EPSG:32632"
            "bounds": {minx: 463560, miny: 5758030, maxx: 469410, maxy: 5767210}
        }
    }]
}


Be careful to use unique IDs
Future implementations will try to detect the type from the url.
newService is used internally as the starting object for an empty service.


projectionDefs configuration

Custom CRS can be configured here, at root level of localConfig.json file. For example:

"projectionDefs": [{
  "code": "EPSG:3003",
  "def": "+proj=tmerc +lat_0=0 +lon_0=9 +k=0.9996 +x_0=1500000 +y_0=0 +ellps=intl+towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68 +units=m +no_defs",
  "extent": [1241482.0019, 973563.1609, 1830078.9331, 5215189.0853],
  "worldExtent": [6.6500, 8.8000, 12.0000, 47.0500]
}]

Explanation of these properties:

  • code - a code string that will identify the added projection
  • def - projection definition in PROJ.4 format
  • extent - projected bounds of the projection
  • worldExtent - bounds of the projection in WGS84

These parameters for a projection of interest can be found on epsg.io

CRS Selector configuration

CRS Selector is a plugin, that is configured in the plugins section. It should look like this:

"plugins": {
  ...
  "desktop": [
    ...}, {
      "name": "CRSSelector",
      "cfg": {
        "additionalCRS": {
          "EPSG:3003": {
            label: "Monte Mario"
          }
        },
        "filterAllowedCRS": [
          "EPSG:4326",
          "EPSG:3857"
        ],
        "allowedRoles": [
          "ADMIN"
        ]
      }
    }, {
  ]
}

Configuration parameters are to be placed in the "cfg" object. These parameters are:

  • additionalCRS - object, that contains additional Coordinate Reference Systems. This configuration parameter lets you specify which projections, defined in projectionDefs, should be displayed in the CRS Selector, alongside default projections. Every additional CRS is a property of additionalCRS object. The name of that property is a code of a corresponding projection definition in projectionDefs. The value of that property is an object with the following properties:
  • label - a string, that will be displayed in the CRS Selector as a name of the projection
  • filterAllowedCRS - which default projections are to be available in the selector. Default projections are:
  • EPSG:3857
  • EPSG:4326
  • allowedRoles - CRS Selector will be accessible only to these roles. By default, CRS Selector will be available for any logged in user.

Search plugin configuration

The search plugin provides several configurations to customize the services behind the search bar in the map:

  • Allow to configure more many services to use in parallel, in the services array.
  • Natively supports nominatim and WFS protcols
  • Allows to register your own custom services to develop and use in your custom project
  • Allows to configure services in cascade, typically when you have a hierarchical data structures ( e.g. search for municipality, then for street name, than for house number, or search state,then region, then specific feature, and so on...)

Following you can find some examples of the various configurations. For more details about the properties, please check to plugin API documentation: https://mapstore.geosolutionsgroup.com/mapstore/docs/api/plugins#plugins.Search

{
   "type": "nominatim",
