Placemark popups in the new Google Earth

Today we are having a look at some things you should know if you are a KML creator with the new browser based Google Earth in mind – with a focus on placemark popups. First, we must note that the new Google Earth is still very much a work in progress, especially with regards to KML support and we can expect major changes to the way it handles KML in the future.

The first thing to note is that the new Google Earth cannot access local files. This is a consequence of being browser based. Browser security does not allow web based applications direct access to files on your local computer. So, if you create a standard KML file which includes links to local images in popups or overlays and open it in the new Google Earth, you will not be able to see the images. If you save the file in the compressed KMZ format, then Google Earth puts the images in the file. That did work for image overlays but not placemark popups. We then tried uploading the KMZ file to Google Drive, as the new Google Earth has built in support for opening files from Google Drive. However, we found that trying to open KMZ files from Google Drive gives an error and only KML files could be opened that way.

Finally, we uploaded the image to GEB and linked it in the KML. When we did this, we found that the images did work correctly in placemarks and image overlays, but photo overlays appear to not be working at this time.

The next thing to note, is that when you place an image in a placemark popup, Google Earth does not know how large the image is until it is loaded. The consequence of this is that in Google Earth classic, the popup may be resized after the image loads. In the new Google Earth, this does not happen. If you close it and open it again, the image has been cached and it opens at the correct size:


Left: Opened for the first time. Right: Opened the second time.

The solution to this it to give the image an explicit size in your popup. An alternative would be to wrap your placemark content in a ‘div’ that has explicit style information.


Always include width and height for your images for better popups. This is true even for Google Earth classic.

Another option is to take advantage of the new popup options. We know of three new modes, ‘card’, ‘panel’ and ‘fullscreen’.

To use them, you have to edit the kml file and put one of these lines in the style information for a popup:

<BalloonStyle><gx:displayMode>fullscreen</gx:displayMode></BalloonStyle>
<BalloonStyle><gx:displayMode>panel</gx:displayMode></BalloonStyle>
<BalloonStyle><gx:displayMode>card</gx:displayMode></BalloonStyle>

See an example of how it is done by inspecting the contents of this sample KML file

The ‘card’ mode does not seem to render HTML:

Also, when you click on it, it opens it full screen. We have not yet figured out how to specify the image. We believe it is intended only for Google’s use and links to Google Maps data via a custom tag: <gx:mid>

The ‘panel’ mode opens in a side panel and we have seen GE Teach make great use of that mode. However, we found that using it on a plain placemark with a single image, it sometimes did not display the image.

The ‘fullscreen’ option displays the contents of the popup full screen and appears to work reasonably well with a simple image.

A couple of observations about the new Google Earth’s imagery

by Timothy Whitehead on May.09, 2017, under 3D Models, Argentina, Australia, Brazil, California, Denmark, England, Germany, Google Earth News, Google Earth Tips, Google Sky, Google maps, Hawaii, Indonesia, Ireland, Italy, Japan, Kenya, Mexico, Natural Landmarks, Netherlands, Sightseeing, Street Views, USA

When the new Google Earth was released, one of the first things we noticed was the faint Google copyright notices in white, which have long been a feature in Google Maps, but never before seen in Google Earth. At first we thought Google had made the decision to incorporate the copyright notices into the new Earth, but as we discovered last week the new Google Earth uses the same imagery as Google Maps and the copyright notices are baked into the imagery. If we compare the two products, we find that at any given zoom level, the copyright notices are in the exact same locations:

Google Earth has long had a problem with image distortion at the poles. The new Google Earth has a similar problem, but generally seems to do much better. Near the North Pole, the sea floor imagery is much clearer in the new Google Earth:

We can tell that the same original sea floor image was used because there is a white stripe at the antimeridian that can be seen in both versions of Google Earth and Google Maps.

The South Pole has a white circle in the new Google Earth (and Google Maps). This is not a significant problem at this time as Google doesn’t have any good imagery of the South Pole anyway.

The new Google Earth imagery database

by Timothy Whitehead on May.03, 2017, under 3D Models, Argentina, Australia, Brazil, California, Denmark, England, Germany, Google Earth News, Google Earth Tips, Google Sky, Google maps, Hawaii, Indonesia, Ireland, Italy, Japan, Kenya, Mexico, Natural Landmarks, Netherlands, Sightseeing, Street Views, USA

Yesterday we had a look at the differences between the Street View layers in the new Google Earth, Google Earth Classic and Google Maps – with emphasis on user contributed content. Since the new Google Earth was released we wondered whether its imagery layer is based on Google Earth’s default layer, or Google Maps.

We noticed that some new imagery has been added to Google Earth Classic. As is usually the case, the new imagery can only be found in the default layer and has yet to be added to ‘historical imagery’. Also, the new imagery has not yet been added to Google Maps. This is the perfect opportunity, so we compared all three products. The location is Arequipa, Peru, where a new image dated April 4th, 2017 has been added. We are looking at the edge of the image.

So it would appear that the new Google Earth either shares the Google Maps imagery database or has its own unique database. We noticed slight differences in colouring between new Google Earth and Google Maps above, but discovered that was caused by the street names and other labels and when we turned those off in Google Maps the images were identical.

If you come across any interesting sights in the new imagery, do let us know in the comments. The most interesting images will probably not be visible until the update is published to ‘historical imagery’.

User contributed photos and the new Google Earth

by Timothy Whitehead on May.02, 2017, under 3D Models, Argentina, Australia, Brazil, California, Denmark, England, Germany, Google Earth News, Google Earth Tips, Google Sky, Google maps, Hawaii, Indonesia, Ireland, Italy, Japan, Kenya, Mexico, Natural Landmarks, Netherlands, Sightseeing, Street Views, USA

One welcome improvement to the new Google Earth over Google Earth Classic is that the user contributed photos now work. For a long time, Google Earth Classic has shown the blue dots representing user contributed photos, but dropping Pegman on them doesn’t work.

However, when you compare the blue Street View layers between the new Google Earth and Google Maps, we find there are a lot less blue dots marking user contributed photos. Below we compare the blue Street View layer around the Washington Monument (Washington DC, USA) in the new Google Earth and Google Maps.

As you can see above, Google Maps has a lot more blue dots. However, if you know exactly where to drop Pegman, all the photos are still accessible in the new Google Earth, they just don’t show in the blue layer. In Google Maps and both versions of Google Earth, the blue layer changes as you zoom in and out and you see more dots as you zoom in, but one would expect that at maximum zoom you should be able to see all user contributed content. Below is a location on Table Mountain where I captured some Street View along one of the trails using a cell phone:


Left: Google Maps. Right: New Google Earth.

As you can see above, none of the blue dots show in the new Google Earth. But if you drop Pegman there, then the images do open. We thought that possibly the layer is out of date, but when we had a look at Guatemala, which got fresh Street View recently, we find that the layer is up to date in the new Google Earth.


Left: Google Maps. Right: New Google Earth.

When zoomed out there is a noticeable absence of blue dots in the new Google Earth as compared to Google Maps.

Google really needs to sort this out and give user contributed content more prominence – especially given that the new Earth does not include the popular Panoramio and 360 Cities layers from Google Earth Classic. Panoramio is set to be shut down completely in November.

One tip for exploring the blue Street View outlines layer in the new Google Earth is to drop Pegman where there is no Street View (in the middle of an ocean for example). A message appears saying “Select a location highlighted in blue to enter Street View” and until you close the message or choose to enter Street View, you can explore without the blue layer disappearing.
