LibGDX: How do I manage Player position?

Question

I'm making a 2D isometric tiled game using LibGDX. In my Player class, I created a vector2 that I named 'pos' to manage the player position, then I draw my Player with:

    batch.begin();
    batch.draw(localPlayer.texture,LocalPlayer.pos.x,LocalPlayer.pos.y);
    batch.end();

Let's say pos = (0,0), then the Player will be rendered at the bottom left corner of my screen.

When I translate the camera, the (0,0) still correspond with the bottom left of my screen, so the pos Vector2 is about my screen, not my map...

What should I do to get a Coordinate System based on the map and not on my screen? I would not prefer using the Sprite Class...

Thank you :)

Have a look at model view protection matrix (matrix transformations): http://www.opengl-tutorial.org/beginners-tutorials/tutorial-3-matrices/

This is related to OpenGL, but the operations are similar in any library.
