Thank you for the nice explanation. Can you please elaborate on CRS and how to choose one that best suites our project, or can you please provide some sources where I can understand the basis of CRS. Many times when I want to add a shape or a raster, it falls in an unintended place, and I have no idea why that happens and what to do.
When working on GUIs, Most GIS programs perform an automated coordinate transformation process when you add your data to it. So it should fall in the right place. But for your question about choosing the right CRS, when coding, you need to understand your GIS data (you can simply import it on QGIS and check its properties to understand it’s original coordinate system). Every collected geospatial data is originally collected on a particular CRS, so you need to explore your data to see what it’s original CRS is before you start to decide if you want to make any reprojections/transformations. The original data CRS (either geographic or projected coordinate system) will be shown in the data properties. You can also do this programmatically but I suggest you start with a GUI to explore the data. As for resources, check out epsg.io for more information about the available CRS.
