Having Projection Issues when Importing CSV Data to GIS?

This tutorial addresses a key issue faced by many when importing data (specifically point coordinates) into a GIS software like QGIS or ArcGIS Pro, which is complications around selecting the coordinate reference system or projection. In this tutorial, we make use of a couple of such datasets which are different in nature, and we discuss the issues that are commonly experienced by GIS users such as not being able to get the points displayed at the correct geographical locations due to errors pertaining to coordinate systems/ projections. In the first part of the tutorial, we make use of a set of coordinates which are in decimal degrees, which belongs to WGS 1984 Geographic Coordinate Reference system. However, during the importing process, we deliberately select a wrong coordinate system, so that we get to see that the points are getting places in a completely different geographical area. However, we go back and re-correct the mistake by selecting the appropriate coordinate system, and we can see that the points are placed now at the right geographical location. Additionally, we also test a couple more scenarios using different coordinate reference system such as UTM and ETRS89 / Portugal TM06 and see the effect of that on the results.
