Well, I didn't have much time to spend on this but here's a quick-and-dirty example of how to calculate the distance and travel time from the "Default position" using the Google Maps API v3 Distance matrix.

Place this in the question source.
<script type="text/javascript" charset="utf-8">	
 
	$(document).ready(function(){
 
		// Identify the map
		var mapSGQA = '{SGQ}';
		var currentMap = gmaps[''+mapSGQA+'_c'];
 
		// Wait for the map to load
		google.maps.event.addListenerOnce(currentMap, 'idle', function(){ 
 
			// Some variable definitions
			var currentMarker = gmaps['marker__'+mapSGQA+'_c'];
			var answerInput = $('#answer'+mapSGQA+'_c');
			var defaultPosition = $(answerInput).val();
			var startLat = $('#answer'+mapSGQA+'_c').val().split(' ')[0];
			var startLng = $('#answer'+mapSGQA+'_c').val().split(' ')[1];
			var startLatLng = new google.maps.LatLng(startLat, startLng);
			var originIcon = 'https://chart.googleapis.com/chart?chst=d_map_pin_letter&chld=O|FFFF00|000000';
 
 
			// Listener on the map events
			google.maps.event.addListener(currentMap, 'click', function() {
				calculateDistances(startLatLng, currentMarker.getPosition());
			});
			google.maps.event.addListener(currentMarker, 'dragend', function() {
				calculateDistances(startLatLng, currentMarker.getPosition());
			});
			google.maps.event.addListener(currentMap, 'rightclick', function() {
				calculateDistances(startLatLng, currentMarker.getPosition());
			});
 
			// Insert the results element
			$(answerInput).after('<div class="distanceResults" />');
 
		});
	});
 
	function calculateDistances(origin, destination) {
		var service = new google.maps.DistanceMatrixService();
		service.getDistanceMatrix({
			origins: [origin],
			destinations: [destination],
			travelMode: google.maps.TravelMode.DRIVING,
			unitSystem: google.maps.UnitSystem.METRIC,
			avoidHighways: false,
			avoidTolls: false
		}, callback);
	}
 
	function callback(response, status) {
		if (status != google.maps.DistanceMatrixStatus.OK) {
			alert('Error was: ' + status);
		} else {
			var origins = response.originAddresses;
			var destinations = response.destinationAddresses;
 
			var outputDiv = $('.questiontext');
			outputDiv.innerHTML = '';
 
			for (var i = 0; i < origins.length; i++) {
				var results = response.rows[i].elements;
				for (var j = 0; j < results.length; j++) {
					$('.distanceResults').html('Start address: '+origins[i]+'<br />\
												End address: '+destinations[j]+'<br />\
												Distance: '+results[j].distance.text+'<br />\
												Time: '+results[j].duration.text+'');
				}
			}
		}
	}
</script>

Hey T,
This is great. I think there are a lot of directions one could go here.

I was working on this, but instead of using the short-text Map-style question, I ended up showing a map inside a short-text text-style question. It is not optimal because the style requirements were pretty hard to work with, however I was able to save the calculated distance as the question's answer.

I assume that this is what this does:
// Insert the results element
$(answerInput).after('<div class="distanceResults" />');

I suppose the "benefit" of using the external map rather than the short-text map-style question is that it might be more easy to implement driving directions, location search and things of that nature. Or is it?

Your solution is really great. Thank you as always for relentlessly adding to the knowledge base.

David

Yes, of course, this could be applied to any map. I just used the LimeSurvey map because it was faster.

Ability to add Google Maps as a question 2 years 4 months ago #111398

Hi,

As some people have mentioned here, I would like a way to implement a search function in Google Maps in a survey. I have very limited experience with web development, so I'm struggling a bit with this (I'm used to writing stand-alone programs, not scripts for webpages). Anyways, I found a LimeSurvey that has successfully implemented a search function and I was wondering if anyone might have any clues as to how to implement this.

bart.etcsurvey.com/index.php/

The first question with Google Maps is somewhere around 7 questions in. The survey remembers your choice as the origin of you trip and shows it on a map later on. I'm currently going through the sources for the webpage trying to see if I get any ideas, but any help would be awesome. Thanks!

Did anyone find a way to include a "Place search box" inside a question that uses Google Maps? It would be really helpful if the functionality shown here can be used to obtain the latitude-longitude values from a Google Maps Limesurvey question without the necessity to move around the map manually.

Thank you for your prompt reply.

What we mean is to have a search bar that will allow survey participant to enter their location and the map will show the specific location in google map.

Right now we use a short text question and enable the google map but the survey participant will need to drag the map to go to his/her location which consume a lot of time unlike if you have a search bar you will just type your address and your location will be display.

Thnaks a lot

LimeSurvey uses Google Maps API v3 so, as stated earlier in this thread, the Google Bar (search bar) doesn't exist. You will need to do the search with an AJAX call to the Google Places API - developers.google.com/places/?csw=1

Hi Folks, another request on this nice feature: anyway that users can enter (either type or copy/paste) their coordinates in the small text field as opposed to dragging the placemarker on the right spot?

Right it seems to be a display only (doesn't capture coordinates that are typed in) - would be very helpful, thanks!
