Meaning of VintageStart and VintageEnd from the map Metadata. RRS feed

  • Question

  • Hello,

    I have created an infobox that displays the Vintage (Imagery acquisition dates) metadata of the current map view.

    I would like to know what is the exact meaning of VintageStart and VintageEnd and which one of the images I am actually seeing in my map??

    I don't really understand the concept of showing two dates when most people would just be interested on the date of the image they are actually looking at...

    Thank you in advance for the explanations!

    My javascript code (using jQuery for the Ajax bit) , in case it could be useful to anyone:

    	function GetMetadata( data)
    	{
    	
    		var startDate = data.resourceSets[0].resources[0].vintageStart;
    		var endDate =  data.resourceSets[0].resources[0].vintageEnd;
    		
    		// Retrieve the location of the map center 
            var center = map.getCenter();
             
    		var south = map.getBounds().getSouth(); 
    		var west = map.getBounds().getWest();
    		
    		var corner = new Microsoft.Maps.Location(south,west);
    		
    		var description = "";
    		
    		if( startDate != null ){
    			description += "First Image " +  startDate + "<br/>";
    		}
    		
    		if( endDate != null ){
    			description += "Last Image " +  endDate;
    		}
    		
    		if( startDate ==null && endDate == null ){
    			description = "Unknown imagery dates";
    		}
    		
    		
    		// Create an info box 
    		var infoboxOptions = {width:300, 
    							  height: 100, 
    							  title: "Imagery acquisition dates", 
    							  description: description, 
    							  showPointer: false, 
    							  
    							  offset: new Microsoft.Maps.Point(-100,0)};
    		var myInfobox = new Microsoft.Maps.Infobox(corner, infoboxOptions);
    		
    		// Add the info box to the map
            map.entities.push(myInfobox);
    	}
    
        function showImageryDates()
    	{
    		var url = 'http://dev.virtualearth.net/REST/V1/Imagery/Metadata/Aerial/${placemark.coord.latitude},${placemark.coord.longitude}?zl=15&key='+bingKey+"&jsonp=GetMetadata&jsonso=abc3144sd";
    
    		$.ajax({
                      url: url,
                      dataType: "jsonp",
                      
                      jsonp: "false"
                  });
     
    	}

  • Most of the time there is no single date for the image. The imagery is captured over a period of time. The vintage start/end dates gives you the time frame that the image was captured in.

  • Dear Rick,

    This is a very old answer, but I would like someone to further clarify if possible.

    The date of the the capture of a VHR Satellite Image or the date that an image is captured in an ortophoto campaign is known (is always part of the metadata of the image)

    Could anyone please review this answer? The date of the imagery is actually important in our application.

    Thank you!

  • As stated previously there is rarely a single date specified for an image as the imagery is taken over a period of time. This is actually even more prevalent now than in the past as a combination of images are often stitched together to create a clear image that is free from clouds. As such, some date ranges can be several years.
