Steven Ho, whose work we often cover has recently updated a Google Earth animation he first created back in 2007 showing the Maokong Gondola of Taipei. We covered his original 2007 version in this post.

Last week we looked at Sentinel imagery coverage and today we are doing the same for Landsat imagery.

Last week we looked at Sentinel imagery coverage and today we are doing the same for Landsat imagery. First, note that we are discussing Landsat 8 imagery only, as Landsat 7 imagery is not currently available on Amazon Web Services (AWS), which is the source of our information. In addition, we have excluded Landsat imagery …

Last week we had a look at drawing contour lines using the Google Maps Elevation API. Because of restrictions on what you are allowed to do with Google’s elevation data, we chose not to create KML files from it. We have since talked to another elevation API provider, Mapzen and they assure us that they use open data from USGS and NOAA and we may do whatever we like with it.

Yesterday we created a KML file that allows you to preview the latest sentinel imagery using a KML file of all the sentinel tiles. We noticed that some tiles do not have any images available so we thought it would be interesting to do a map of Sentinel coverage. There are 56,686 tiles so it took a little while to check all of them to see whether they have imagery and what the date of the latest image is. It turned out that only about half the tiles (27,256) actually have imagery.

Thank you to GEB reader ‘DJ’ for suggesting this idea in the comments of our post on simulating lakes. It turns out that the algorithm for drawing contours given a regular array of altitude data is actually very simple. We used the algorithm known as ‘Marching Squares’ as described on Wikipedia. For this first attempt we are not going to bother with some of the extras, such as smoothing the final result, or dealing with saddle points.

Google has just released Street View imagery of Komodo Island, Indonesia, as well as significantly increasing the coverage for the rest of Indonesia. There are also a number of new underwater Street View locations in the region, which you can read more about on Google’s Lat Long blog.

Last week we created a KML file to easily preview the latest Landsat imagery. The data comes from Amazon Web Services (AWS), which hosts a large amount of Landsat 8 imagery and also includes some handy thumbnail images. So, we have now created a KML file that automatically creates animations from the thumbnail images.

Earlier this week we created a KML file to allow you to preview the latest Sentinel imagery. We used the fact that Sentinel imagery is available via Amazon Web Services (AWS). Given that Landsat 8 imagery is also available on AWS we thought it would make sense to do the same for Landsat 8 imagery.

As we mentioned in Monday’s post, southern Louisiana is experiencing major flooding. One of the worst affected areas is to the east of Baton Rouge, where the Amite River has burst its banks, flooding several neighbourhoods.

One of the worst affected areas is to the east of Baton Rouge, where the Amite River has burst its banks, flooding several neighbourhoods. We were able to find a Sentinel image captured on August 14th, 2016 which shows the extent of the …

When there are major events such as the ongoing flooding in Louisiana we often check whether the events are visible in Sentinel or Landsat imagery. Given that any given location is only covered about every 10 days by Sentinel and every 16 days by Landsat 8, the first thing we want to check is when the most recent images were taken and whether or not they are any good.

We mentioned in our post on simulating lakes that Google Earth’s elevation data is often very inaccurate in mountainous areas. When looking around the 3D imagery of Rio de Janeiro, where the Olympics are currently taking place, we realised it would be an ideal place to actually check how inaccurate Google Earth’s elevation data can be.

In yesterday’s post we had a KML which includes a polygon showing the approximate extent of a historical lake in Google Earth. We thought it would be worth discussing how to do this and some of the things to look out for.

The amazing things about Google Earth
Introduction
This blog is not officially affiliated with Google. Google Earth Blog is dedicated to sharing the best news, interesting sights, technology, and happenings for Google Earth. You will find the most amazing and interesting Google Earth news stories and content you can download right off the site. Learn how to take data from your GPS, map it into Google Earth, and share it with friends or the world. Learn when new releases of Google Earth come out, hear about new technologies and features, or check out the links to dozens of other Google Earth web sites.

When Frank Taylor first saw Google Earth he knew it would be a popular phenomena. All sorts of amazing things were going to happen because of Google Earth. And, amazing things have happened, indeed, in the 6+ years since this blog was started. Over 2000 blog posts here are a testament to Google Earth.
