Fetching the on-click data from the website into QGIS

Geographic Information Systems Asked by MKR on November 8, 2020

I would like to fetch the on-click data into QGIS and show them as the placemarks.

Basically the issue comes from i.e this website:

https://eclipse.gsfc.nasa.gov/SEgoogle/SEgoogle2001/SE2024Apr08Tgoogle.html

whereafter the on-click you are getting the local circumstances for the phenomenon.

If, for example, I take into account, when the event start (stressed on the red), I must look for exactly the same time around the shape (which is the umbra in this case), as per below:

The issue is time-consuming since the website doesn’t provide the download option for these circumstances. On top of that, there is no option do download these on-click points as a.geojson format for example.

It put me into a difficult and tedious situation, where I have to literally draw out the whole shape manually, as per below:

but this is not the end, as I cannot download the on-click points, as I mentioned above. Now if I want to get this shape externally, I have to redraw it in a different place. I used to do it in the ScribbleMaps, and save it as a .kml file afterward.

Next, I could display it i.e on Google Earth.

The same thing I can do with the QGIS if I select the Google Satellite imagery from the QuickMapServices and create the shapefile layer, where I will start drawing the shape.

How do I get these on-click circumstances into QGIS as a layer?

More details of my problem are here:

UPDATE:

I just made it a bit quicker copying the coordinates from the pop-up window. Unfortunately the process is still far too long, as I need about 180 single points to add up on my layer:

Calculations shown in the popup are getting calculated on the fly based on marker location. You can use their implementation to get all text shown for particular location.

I have created a demo https://jsfiddle.net/310fm6se/1/. you can enter latitude & longitude to get calculated eclipse times.

This can be also used to automate and calculate eclipse times for bunch of coordinates.
