Simple Tile Map

Good Day...

I would like to ask on how to implement or load a script in the beginning of the game to create a map with the corresponding topography(to which is predefined in the array). I know how to write the code but the problem is on how to successfully implement it on Unity. I am having a hardtime just to adjust the camera. And also after the map has been created it will have view like Clash of Clans type of view(camera). Can anyone help me on this one...

Thanks....
