There are missing parts in the scenario, so they are added.
6-1. The user manipulates the map to change the scale.
6-2. At this time, an event occurs due to a change in map scale and the map scale is adjusted.
6-3. In order to change the scale, both the terrain and buildings I created and Windy's weather expression layer must be changed almost simultaneously.
7-1. If the user turns off the Windy function, the terrain and buildings are displayed at the current changed screen scale.
