Hello everyone! I hope you are safe and fine.
Many people ask me about a good place to start learning Python and GIS programming for free. I know there are a lot, so it is easy to get overwhelmed by the resources of the internet. Another thing is when you start a course and get to the halfway you find that the software already has an updated version with many new things to consider. So let me suggest Geo-Python for basic Python for everyone who haven’t tried programming before. It is free, updated and very well explained. Need something adventurous, try Automating GIS-processes course which explained the basic GIS terms and techniques using free tools and simple english. These contents are prepared for university students in mind but people who left universities, waiting to get admitted or simply left in disguise will find them equally helpful. (ps.

These maps are created by NASA and the European Space Agency using Sentinel 5P images to visualize the impact of lockdown due to Coronavirus across China. The map on the left is before the quarantine and on the right is during the quarantine. The Sentinel 5P satellites have detected significant decreases in nitrogen dioxide (NO2) over China. By January 23, 2020, Chinese authorities had shut down transportation going into and out of Wuhan, as well as local businesses, in order to reduce the spread of the disease. The maps here show the concentrations of nitrogen dioxide, a noxious gas emitted by motor vehicles, power plants, and industrial facilities. Scientists argue that this might also be the impact of the Lunar New Year celebration, but the reduction rate in these materials have exceeded any measures seen in the past.
