The Strange Sights of Jiayuguan

by Timothy Whitehead on May.18, 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

We were investigating China’s new Silk Road that has been in the news recently (find various maps via Maps Mania), and we came across some strange shapes in the city of Jiayuguan, China.


The most striking is this square with an ‘X’ and various zig-zag lines.


Next to it are two other shapes.

There are also many other zigzags that look like ditches and what look like power lines of various sizes crossing the area. If any of our readers knows what the shapes are, please let us know in the comments. We don’t think they are ancient ruins, as those are reasonably well documented and consist of a fort and a wall across the pass that is the Western end of the Great Wall of China (which actually consists of lots of separate walls).


Jiayuguan Fort

Nearby there is a large geoglyph apparently made with trees. According to this post it is the Chinese character ‘lóng’ in cursive script.


At 1 kilometre high, it must be a record, but we couldn’t find any references to confirm that.

On the nearby hills, there are three more geoglyphs that are part of the Rhythms of Life series by Andrew Rogers that we covered in 2011. Read more about them here.


“Rhythms of Life”. Part of the Rythms of Life series by Andrew Rogers.


“Caveman”. Part of the Rythms of Life series by Andrew Rogers.


“The Messenger”. Part of the Rythms of Life series by Andrew Rogers.

There are many other interesting patterns in the region such as a wavy line along the railway line that we believe is for drainage, and some buildings and other structures laid out in arrays.

Calibration Targets 3: China

by Timothy Whitehead on May.16, 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

This is the third in our series on calibration targets. Note that such targets are used for both satellite imagery as well as imagery captured from aircraft. Today we are looking at some calibration targets in China and other interesting sites found in the same region.

Thank you to GEB reader Kengrok for pointing us to this site showing a variety of patterns:

Next is a set of lines that we covered back in 2011

Nearby is another similar shape, next to a large square. Plain squares are actually quite common for satellite calibration targets, but this particular square probably serves some other purpose as it is not an exact square and is much larger than is typically used.

Here is a smaller square that at first sight appears to have bomb craters on it, but looking back at when it was either being made or repaired, it looks like the patches were always there.

Older image on the left.

Here are what appear to be fake houses used for target practice. The later deterioration might be due to bombs being dropped on them or it might just be weathering, but the older image certainly looks like they were bombed – but again, we may be mistaken.

Here are some large scale markings that look reminiscent of runways, but we believe were never used as such:

For scale, the small square above and bombed houses are marked with arrows.

We believe these next two are either calibration targets for radar, or tests to see if certain patterns can be used to hide objects from radar:

Although it has nothing to do with satellite calibration as far as we know, there is an enormous scale model of a region from the disputed border between China and India. We previously looked at it in 2006.

And finally, here is some giant writing:

We don’t know if it is intended to be read by satellites or from passing aircraft. The ground seems fairly flat so we don’t think it is intended to be read from the ground.

The Jiangsu tornado

by Timothy Whitehead on Sep.21, 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

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. One such instance is a region in Jiangsu Province, China which was struck by a deadly tornado on June 23, 2016. 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, 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.

Although the latest imagery is not very high quality, near total destruction of houses all along the path of the tornado is clear, especially when comparing it with older imagery.
