  1. Once inside the selection window, you can choose the appropriate CRS from the list. For instance, if you’re working with data from the United States, you might consider selecting “WGS 84”. Additionally, if you know the name or code of the CRS, use the search bar for quicker access. After selecting the desired CRS, click “OK” to confirm your choice. You should then see the CRS ID reflected in the input box.
