Merge Feature

To merge features first make them intersect by modifying or dragging them on map. Then multi select them by holding Shift key and click Merge button from the toolbar.

To save merged features pass callback function to the mergeFeatures function.

Callback Function

• callback - Function to be called back. Response will be passed to this function. It should be handled inside this function.

  Response structure

  • success - true | false. If value is true then features were successfully merged. You can check value property to get the feature id. If false then it means merging failed. You can check message property for the reason of fail.
  • message - Additional message about the result of the call.
  • value - It will contain the feature id if call succeeds. If call fails this property will be null.

Example

// Initialization of the map
var options = {
    tileSettings: {
        source: 'xyz',
        url: 'https://gomap.az/smoothtiles/maptile.do?lng=az&x={x}&y={y}&z={z}&f=png&dp=0'
    },
    targetElement: 'map' // Id of the <div> element. Container of the map.
};

GisTools.initializeMap({options: options});

var options = {
    userId: '00000000-0000-0000-0000-000000000001',
    featureIdList: ['00000000-0000-0000-0000-000000000001', '00000000-0000-0000-0000-000000000002']
};
GisTools.loadFeatures({options: options});

// Adding select interaction
var interactionOptions = {
    type: 'select'
};
GisTools.addMapInteraction({options: interactionOptions});

var guideMergeButton = document.getElementsByClassName('guide-merge-button');

guideMergeButton[0].addEventListener('click', function () {

    GisTools.mergeFeatures(callBack);

    function callBack(response) {
        if (response.success === true) { // Success
            console.log(response);
            alert(response.message);
        } else if (response.success === false) { // Fail
            console.log(response);
        }
    }
});
