Find the Elevation of any Location

According to WikiPedia: the elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface.

In the geo-spatial industry, getting and working with the elevations of points is a very common task for many obvious reasons. Elevation value of points can be obtained through various techniques such as land surveying and GPS observations.

Using the techniques above, there will be a challenge when you need to obtain the points that are difficult to access. In such situations, you will have to consider a remote service to get such elevation values. One of such remote services that provide access to elevation data we will discuss in this blog post is: Open-Elevation.com

Jupyter Notebook Python user input() function

Jupyter notebook has added a feature I have always wished it had long ago. Before now, writing a script that accepts input from user with the input() function in python3 or raw_ input() function in python2 was almost impossible and you have to switch between the terminal window and the jupyter notebook all the time.

The newer version of jupyter notebook has made available a text-box right inside the browser whenever you call the input() function as seen below;-

Enjoy the new GUI feature of the jupyter notebook.
