Layer Control

addLayer(layerObj, placement)

Adds a layer to the map. This adds a layer to client as if it were coming from the configuration. This layer becomes accessible via the LayersTool and well as on the globe. This does not add the layer to the mission’s configuration.

For a more “temporary” layer, use Leaflet directly through L.{leafletLayer}.addTo(mmgisAPI.map). See here for reference on how to construct Leafletjs layers.

Function parameters

  • layerObj - the full mmgis layer object configuration (GET http://localhost:8889/api/configure/get?mission={mission} to get sample layer objects from the existing configuration). At minimum layerObj.name and layerObj.type are required.
    • layerObj.name - A unique name/uuid for the layer
    • layerObj.type - One of the support MMGIS layer types: data, header, model, query, tile, or vector
  • placement - optionaL - Where in the list/tree to add this layer relative to other layers.
    • placement.path - A path to a header in ‘layers’ to place the new layer. A simple path (‘sublayers’ are added). Defaults to no group. Use a dot-notated string for nestings.
    • placement.index - Index in ‘layers’ (or path) to place the new layer. Out of range placement indices are best fit.

Returns a Promise when the layer is added and loaded.

The following is an example of how to call the addLayer function:

window.mmgisAPI.addLayer({ name: "Sample Header", type: "header" }).then(() => {
  console.log("added and loaded");
});

window.mmgisAPI
  .addLayer(
    {

trimLineString(layerUUID, time, timeProp, trimN, startOrEnd)

This function is used to trim a specified number of vertices on a specified layer containing GeoJson LineString features. This makes the following assumptions:

  • If trimming from the beginning of the layer, the time in the time parameter must be after the start time of the first feature in the layer

The following is an example of how to call the reloadLayer function:

window.mmgisAPI.reloadLayer("Earthquakes");

asLayerUUID(uuid)

If uuid is a valid uuid, it is returned. If not but it’s a valid layer Name, it will return the first corresponding uuid. If still not, returns null.

The following is an example of how to call the asLayerUUID function:

window.mmgisAPI.asLayerUUID("4d04b08d-4d13-4ff5-ad3c-f78e9b6425e4");

The following is an example of how to call the toggleTimeUI function:

window.mmgisAPI.toggleTimeUI(false);

setTime(startTime, endTime, isRelative, timeOffset, currentTime, customTimes)

This function sets the global time properties for all of MMGIS. All time enabled layers that are configured to use the Global time type will be updated by this function.

Note that layers will not be refreshed on the map until reloadTimeLayers() (or reloadLayer() for individual layers) is called.

Function parameters

  • startTime - Can be either YYYY-MM-DDThh:mm:ssZ if absolute, or hh:mm:ss or seconds if relative
  • endTime - Can be either YYYY-MM-DDThh:mm:ssZ if absolute, or hh:mm:ss or seconds if relative
  • isRelative - If true, startTime and endTime are relative to the current UTC time
  • timeOffset - An offset to use for the current UTC time; can be either a string in hh:mm:ss format or an integer value in seconds
  • currentTime - If set, offset is ignored and the current working time is set to this currentTime
  • customTimes - Sets an array of times of format YYYY-MM-DDThh:mm:ssZ to be used while replacing {customtime.0}, {customtime.1}, … in the tile or vector layer url in order to inject custom times.
    • If value is a string, puts it into the 0th index of the internal customtimes array.
    • If value is a [string], replaces the current internal customtimes array with it.
    • If value is the empty array [], clears the internal customtimes array.
    • If value is null, does not modify the existing internal customtimes array.

The following are examples of how to call the setTime function:

window.mmgisAPI.setTime("2021-05-13T01:00:00Z", "2021-05-13T07:00:00Z", false);

window.mmgisAPI.setTime(7200, 0, true, 3600);

setLayerTime(layer, startTime, endTime)

This function sets the start and end time for a single layer. It can be used to override the global time for the layer. Note that setTime also updates the times for layers that use the Global time type.

For layers that use a single time, endTime is used (i.e., {time}=={endTime})

Note that the layer will not be refreshed on the map until reloadTimeLayers() (or reloadLayer() for individual layers) is called.

Function parameters

  • layer - The layer name string or a layer object

project(lnglat)

This function convert a Longitude, Latitude object into X, Y (i.e. Easting, Northing) coordinates. It uses the map’s base projection and the proj4 library to perform the transformation.

Custom map projections can be set in the Configuration page’s Projection tab. Otherwise, the default proj4 string is +proj=merc +lon_0=0 +k=1 +x_0=0 +y_0=0 +a={radiusOfPlanetMajor} +b={F_.radiusOfPlanetMinor} +towgs84=0,0,0,0,0,0,0 +units=m +no_defs

This function is the inverse of the project function. It takes in a X, Y object and returns a Longitude, Latitude.

The following is an example of how to call the unproject function:

window.mmgisAPI.unproject({ x: 8120633.560692952, y: -237291.62355915268 });
// returns {lat: -4.000000000000019, lng: 137}

overwriteLegends(legends)

This function can be used to overwrite the contents displayed in the LegendTool. This can be useful when used with the toolChange event listener in the mmgisAPI.

Function parameters

  • legends - An array of objects, where each object must contain the following keys: legend, layerUUID, display*name, opacity. The value for the legend key should be in the same format as what is stored in the layers data under the _legend key (i.e. L*.layers.data[layerName].\_legend). layerUUID and display_name should be strings and opacity should be a number between 0 and 1.

The following is an example of how to call the overwriteLegends function:

const legends = [
  {
    color: "#00e400",
    strokecolor: "#000000",
    shape: "continuous",
    value: "0 - 54",
  },
  {
    color: "#ffff00",
    strokecolor: "#000000",
    shape: "continuous",
    value: "54 - 154",
  },
  {
    color: "#ff7e00",
    strokecolor: "#000000",
    shape: "continuous",
    value: "154 - 254",
  },
  {
    color: "#8f3f97",
    strokecolor: "#000000",
    shape: "continuous",
    value: "254 - 354",
  },
  {
    color: "#8f3f97",
    strokecolor: "#000000",
    shape: "continuous",
    value: "354 - 424",
  },
  {
    color: "#7e0023",
    strokecolor: "#000000",
    shape: "continuous",
    value: "> 424",
  },
];

window.mmgisAPI.overwriteLegends(legends);
