1]]> Although Google has neglected to update ‘historical imagery’ in Google Earth since early June, they have been adding fresh imagery, and when it is reasonably good quality, it goes into the default layer and we can see it. According to Wikipedia, the tornado killed at least 99 people and injured 846 others (152 critically).

We found a number of articles showing various photos of the destruction, such as here, here, here and here. But. actually locating the event proved more difficult. We first mapped out the area that had new imagery and started searching through it for signs of damaged buildings, but with an area of nearly 4,000 square kilometres we were not successful. We did find a raised railway under construction. google earth blog NorwegianPearlSeattle And a long trail of destroyed houses that turned out to be planned road construction. The articles either mention major nearby cities or small villages that aren’t marked on the map and couldn’t be found through search. Eventually we found mention of “Danping Village of Chenliang Township” and we were able to find Chenliang. From there, the path of destruction was easy to trace over a distance of around 30 km.

The post Malaysia and Tunisia get 3D appeared first on Google Earth Blog.

]]> Malaysia and Tunisia have recently received their first 3D imagery. Tunis and Sfax in Tunisia and Sungai Petani in Malaysia.But in some cases it is important to get it right. We had a problem with this in the past when we created a script to draw arcs. If we used absolute altitudes the ends of the arcs ended up all at a fixed altitude instead of ground level.

4]]> Although it is not directly related to Google Earth, Global Fishing Watch does use geographic ‘big data’. So we thought it would be worth covering. Global Fishing Watch is a partnership between Google, Oceana and SkyTruth, which aims to track the world’s fishing fleets and monitor where they fish. This will help to identify illegal fishing as well as assist in the management of fisheries. Read more about it on Google’s Lat Long blog.

To use it, start here. It requires you to sign up to use it, but the signup process is fast and free. We believe the signup is required because of the sensitivity of the data. And they require you to acknowledge that you realise the data may be inaccurate, among other things. Learn what you can do and how to use it from the tutorial here.

They do not provide an API nor any way to export data to Google Earth. The data can be accessed by their research partners via Google Earth Engine. They state, however, that the underlying ship tracking data is a commercial data-set, so they cannot distribute it freely. We really wish that shipping data and aircraft data could be made available freely, but Global Fishing Watch states that it downloads 20 million data points per day, so whoever is managing the data collection must have significant costs.

We came across this interesting track that follows lines of longitude (every four degrees). And then another ship takes over and continues the pattern further west. Was it doing some research as well as fishing?

6]]> We have long had a fascination with cruise ships in Google Earth. Cruise ships represent a significant amount of area and deserve to be mapped, but because they move from place to place this poses an interesting mapping problem.

Some time back we had started making a collection of placemarks for various ships in 3D, but never got around to completing it. In some cases, the name of the vessel can be seen in the imagery, but at other times, identifying it requires a bit of detective work. Yesterday, GEB reader Frank (not Frank Taylor), who also contributes outlines for our 3D imagery KML, sent us a collection of placemarks for cruise ships and ferries in 3D, which was much more comprehensive than ours. So, we have combined it with our collection and are providing it here in case our readers are interested.

Grab the collection here. We have implemented it as a network link and may update it over time, but do not guarantee that we will have time to do a lot of regular maintenance.

We found that a few of the placemarks we had created in the past no-longer have cruise ships at those locations. Also interesting is that some of the cruise ships in the imagery have since been sold and renamed or in some cases, such as the Sky Wonder, have since been scrapped.

A number of cruise ships appear more than once in the 3D imagery. For example:

The post Cloudy places are hard to photograph from space appeared first on Google Earth Blog.

10]]> In yesterday’s post we talked about Landsat imagery and how in some locations there are only a few cloud-free images per year. That was not entirely accurate, as there are some places where it is practically impossible to find a cloud-free Landsat image.

We were recently exploring the north-western area of Colombia (looking for circular islands). And noticed that the imagery there is of particularly poor quality. Most of Choco Province, Colombia, has no high resolution satellite imagery and instead uses the global mosaic. created from Landsat imagery. To make the global mosaic, Google took Landsat imagery captured over multiple years and searched for cloud-free pixels to use in the final mosaic. However, when we looked at the region with our Landsat animations KML. we found 49 images captured over the last three years. But they all had significant cloud cover.

google-earth-blog-abstractart

google earth blog AbstractArt

Some areas look like abstract art. Another place with a similar problem – year round cloud cover – is the rainforest belt of Central Africa. In some places, Google has had to use Landsat 7 imagery, which we can see because of its characteristic stripes due to a faulty component on the Landsat 7 satellite.

google-earth-blog-riverknot

google-earth-blog-riverknot

3D imagery is above the default terrain, so intuitively one would expect relative altitudes to move upwards when you turn on.

google earth blog riverknot

We are not sure whether the above effect is due to just cloud cover. Seasonal changes in the water levels or the fact that the water colour changes over the seasons.

For an understanding of which parts of the globe have the most cloud cover, see this animation from NASA. Note that it is not images of clouds. But rather maps of the average amount of cloud cover over a month. We could not find a version for longer periods to find out which locations have near-permanent cloud cover.

12]]> We recently came across this interesting article by National Geographic about a recent study of land/water changes over the last 30 years. The study is by researchers at the Deltares Research Institute, who used Google Earth Engine to gather and process the data. The data itself comes from Landsat imagery.

Sadly, we were not able to figure out a way to view the data in Google Earth. Was notable for being able to easily display maps in Google Earth. This is a pity, because we find Google Earth a much better platform for exploring this kind of data.

Nature Climate Change,. However, the data itself is published as a publicly available 2D map.

Most inland water bodies are quite seasonal, so we wonder how the researchers corrected for that. The Landsat imagery typically covers each spot on earth once every 16 days. This often means only a few good images per year. For the global mosaic used in Google Earth, many different images over multiple years are combined together to get the cloud-free image. But can vary considerably from year to year (more on this in a future post) This doesn’t apply to coastal land reclamation, which tends to be permanent.

The difference between relative altitudes and absolute altitudes is not always obvious. But in some cases it is important to get it right. We had a problem with this in the past when we created a script to draw arcs. If we used absolute altitudes the ends of the arcs ended up all at a fixed altitude instead of ground level. The eventual solution that we came up with was to use absolute altitudes and read the end point altitudes from Google’s Elevation API.

16]]> Yesterday we made some Google Earth tours of various US parks. We recorded the tours using Google Earth’s built in ‘Record a tour’ button on the tool bar and then navigating with a SpaceNavigator 3D mouse. Everything seemed fine until we played back the tours and found that some of them have bumps in them and occasionally some have quite severe up and down jitter. We found that these effects were actually part of the tours as they would occur in the same place when played again.

Thus Google Earth recorded the wrong altitudes when recording the tour. And when playing it back new altitude data is available. So it looks wrong. After much investigation. We do believe that is the main cause of the problem, but that there are other issues as well. google earth blog York Minster

We thought it would be interesting to try and fix the tours by using some maths to smooth out the altitudes. However. Smoothing them out may be difficult or impossible. Google Earth can store altitudes in two basic ways: relative to the ground (or sea floor). or an absolute measurement (from sea level). A third option is to leave out the altitudes and have objects automatically clamp to the ground level.

Because we cannot smooth them out without knowing what the ground altitude is at each point. Oddly enough, this contradicts what it says on this page. Which states that Google Earth uses absolute altitudes for tours precisely because of the problems we are experiencing.

As we noted in this post. when viewing areas with 3D, Google Earth shows the altitudes from the 3D imagery in the status bar. Or whether it uses the 3D imagery where available. What we found was surprising.

Typically. 3D imagery is above the default terrain, so intuitively one would expect relative altitudes to move upwards when you turn on. 3D imagery. What happens is the opposite. They move downwards. This is because.

The two scenes below illustrate what happens. In both cases we have some lines set to a fixed height relative to the ground:

17 August month-end post we mentioned that Monument Valley, Arizona / Utah was now in 3D in Google Earth. Several other US parks also received 3D imagery at the same time. What we didn’t realise at the time was the reason why. Google added 3D for several US parks at the end of August. It was because the US National Park Service celebrated its hundredth birthday on August 25, 2016. earthtopomaps.com

So, to show off the 3D imagery available for US Parks. Including both the new releases and areas that already had 3D (which we looked at last October). We have created some Google Earth tours, which you can view in Google Earth with this KML file. We have also recorded a select few of them in the YouTube video below:

Note that we haven’t created tours for every US park that has 3D. We have included outlines for the parks we know about that have 3D. If you notice we have missed any, please let us know in the comments.
