A burnt out plane and some imagery errors

On August 3rd, 2016, Emirates Flight 521 carrying 282 passengers and 18 crew crashed while landing at Dubai International Airport. One fire fighter died in rescue effort but all the passengers and crew survived. The plane was almost entirely destroyed by fire. See pictures and video here. DigitalGlobe captured an image of the airport just five days later. Being a busy airport the wreckage had been moved out of the way, but can still be seen:

We also noticed that in that location if you switch to ‘historical imagery’ Google Earth incorrectly continues to show the default layer. Only when you switch to older images or zoom out does it disappear. It appears Google has got some settings wrong on the imagery there.

While investigating other imagery updates including some flooding in Australia in September, we came across some patches of blurred imagery:

At first it looks like censorship, but given the location and the large number of blurred patches (at least eleven), we believe it is where there were clouds in the original image. Normally, for the default layer, Google replaces cloudy patches with older imagery. However it appears to have gone wrong in this case. We later found the same effect in Bangladesh, so it is not an isolated incident.

Also in Bangladesh we came across a strip of imagery that at first looks like it is out of alignment or has been misplaced. However, on closer inspection we believe it is simply that the river has changed significantly between May 2016 (the strip) and November 2016 (the background) when the two images were taken.

DigitalGlobe’s WorldView-4 sees first light

by Timothy Whitehead on Dec.08, 2016, 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

We wrote about DigitalGlobe’s WorldView-4 back in August and again when it was expected to be launched in September. However, the launch was subsequently delayed and actually took place on November 11, 2016.

DigitalGlobe has recently released WorldView-4’s first public image, taken on November 26, featuring the Yoyogi National Gymnasium in Shibuya, Tokyo, Japan.

And here is part of the image zoomed in, showing the full resolution:

You can see people in the tennis courts (identifiable by their shadows). Overall, the resolution and colours are clearly better than the average satellite imagery found in Google Earth, but of course not as good as most aerial imagery.

You can download the full high resolution image from the DigitalGlobe website as well as learn more about the satellite and watch its launch.

As we discussed previously, WorldView-4 has similar capabilities to WorldView-3, so don’t expect to see higher resolution imagery than anything previously seen, but do expect a greater quantity of good quality, high resolution imagery. The location of such imagery will depend, as always, on suitable weather conditions and interest from DigitalGlobe or its customers and whether or not it is passed on to Google for inclusion in Google Earth.

Moving sand in Landsat animations

by Timothy Whitehead on Dec.07, 2016, 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

Last week Google added global mosaics in historical imagery for each year going back to 1985. The mosaics are created from mostly Landsat imagery with a bit of Sentinel 2 imagery for the last couple of years (the Sentinel 2 satellite is new). The mosaics are created by gathering all the Landsat/Sentinel 2 imagery for a given year and looking for cloud-free and snow-free pixels then combining the images to create a single global mosaic for the year. Although it is fantastic for viewing long term change, the overall result is that we actually miss out on short term changes.

Back in July we wrote a post about watching sand dunes move with Google Earth imagery. Today we are looking at a similar concept, but with Landsat imagery instead. In August we created a KML file that automatically creates animations using Landsat imagery with thumbnails from Amazon Web Services. We used that tool to create the two GIF animations below:


Sand blowing in the Sahara (southern Libya). Explore original animation.


Sand blowing and irrigation circles in Oman. Note especially south west of the centre of the animation there are wisps of sand moving north west. Explore original animation.

What we found interesting is that established dunes hardly move at all over the three years covered by the animations, but loose sand can clearly be seen moving. It looks no different than sand being blown on the beach. Yet the scales involved in the animations are tens of kilometres and a three year period.

You will also notice in the second animation the dunes to the north east appear to pulse sharper, then softer again. This is because the angle of the sun affects the shadows during the course of the year.

Amazing animals on Google Street View

Panoramio photos not showing in Google Earth

by Timothy Whitehead on Dec.06, 2016, 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

[UPDATE 7-December-2016: The Panoramio Photos Layer is working again. A temporary one day issue.]

Thank you to GEB readers Frank, Manuel, Jim and Gabriel for letting us know that the Panoramio photos are not displaying in Google Earth. The layer and placeholder icons are there but when you click on them the images do not display.

In October Google did announce that it was shutting down Panoramio in favour of Google Street View. The announcement said that as of November 4th, 2016, new signups and uploads would be stopped. However, they indicated that users had until November, 2017 to download their photos and optionally transfer them to Street View. We assumed that this meant that they would keep the API that Google Earth uses running until November 2017. It would seem that that may not be the case.

If Google has shut down the Panoramio API it would be a great pity, as many parts of the world have almost no Street View photos whereas, Panoramio has near global coverage. We have recently been experimenting with capturing photos for Street View and the process is not well thought out and it seems to be impossible to put the captured photos in the correct place when Street View misplaces them. It makes logical sense for Google to only have one 360 degree photo service but they really need to improve the Street View offering as far as user contributions are concerned before completely shutting down Panoramio.

The loss of Panoramio photos in Google Earth is only one of several similar changes. In October two of the Google Earth weather layers were dropped. Recently we also noticed that the Earthquake layer is not updating correctly.
