The maps depict information about the exchange of rooms between five years ago and the present.
After analyzing the maps, it can be clearly seen that five years ago, in the northwest direction, a classroom was established in the former map while, in the present year, in the same direction, it had been replaced by an audio room in the later map. The meeting room and book information below the classroom were unchanged. Furthermore, there was free land available in the southwest direction in the first year; however, in the same direction, a printing machine was placed in the second year.
Further, the maps show that in the earlier map, an office had been present in the southeast direction while a conference room was constructed by the authorities in the present year. Toward the middle of the map, study tables had been present and did not experience any change. Apart from this, shelves and books were placed in the same direction in both maps.
It is evident that many modifications had taken place in the exchange of rooms; some places were changed, and some remained the same in the given time period.
