Hello GopaKumar N G,

latitude and longitude in form view from Google Map

Place one button in form view and click method call from js 

like this,

<button string ="Geo-Location" id="geolocation_id">

this._super.apply(this, arguments);

            var self = this;

            $el.click(function(ev) {

                if (node.attrs.id === "geolocation_id") {

# Here You can Open Google map

# and get latitude and longitude values and pass it to python and update your form view field.

Thank You!
