What is the difference between a geographic coordinate system and a projected coordinate system?

  • This looks like two questions so to fit the Q&A format of GIS-SE would you be able to focus this Question on the one you would like answered first, please?

  • This looks like you are trying to re-use a closed Question for a new one. I recommend that this one is rolled back and remains closed (as a duplicate) and that a second Question be asked with considerably more detail about what exactly is being asked.

    As someone who wants to know the answer to this question, the other question talks about different concepts which just confuses me. As such, although I understand what this question is asking I do not understand what the other question is asking. I believe this question should be 'unduplicated'

    I'm voting to close this question as off-topic because this question the users should have know already before ask a question.
