The given maps provide information about the changes that have been taken in a conference hall in 2009 compared to 2010.
Overall, it is apparent that some certain transitions have been made to develop the layout of the conference, including the introduction of new services and modifications in the functions of rooms.
First of all, in 2009, the registration was placed in the middle-top section of the room, but a change occurred in 2010 that replaced it with a refreshment. Moreover, the main and side entrances located in the northwest and northeast, respectively, remained unaltered over the period. Notably, on the left-hand side of the conference, there were two rooms used as a concert hall and the other one was a meeting room with a stage inside. Both of them were equipped with several seats, but just a year later, these two areas were combined into an exhibition area.
Meanwhile, there was an exhibition area placed in the bottom of the room, before reconstructing for more space to erect a concert hall with a stage in 2010. In the same given timeframe, the registration moved to the right side of the conference, along with the removal of the display area on the left. Furthermore, the balcony in the east side stayed on that same position between 2009 and 2010, but underwent a slight alteration, with the addition of a lounge area inside of it.
