In conjunction with GPS information, the disaster prevention information of your current location is combined with the live-action video taken by the camera.
[About the recording area]
This app is an application that displays the tsunami inundation depth information of "Chigasaki City, Kanagawa Prefecture", the probability of passing through the area, the road blockage rate, the risk of building collapse, the risk of fire, and the risk of liquefaction in AR.
[About operation] When
started, the camera image is displayed in the upper half of the screen, the map is displayed in the lower half, and the hazard information is combined and displayed in the landscape. I am using a gyro and a compass, and when I move the terminal, the displayed contents change according to the direction, and disaster prevention information in the direction I am currently looking at is displayed.
The degree of risk is color-coded in 5 levels, and the color is superimposed on the ground of the live-action landscape on the camera live-action screen above.
The legend is displayed at the top of the live-action screen, and the map at the bottom half of the screen can be moved by touch operation. You can zoom in and out on the map with a two-finger pinch-in / pinch-out operation. When it starts up, GPS detects the position of the terminal and the map displays the current location. When you move the map by touch operation, GPS is automatically turned off and you can move the map from your current location. By pressing the current location button, you can reposition your current location from GPS.
[Details of disaster prevention information]
1. AR tsunami inundation depth information display
Press the [ Inundation depth ] button to display the tsunami depth expected in the live-action video. In Kanagawa Prefecture, tsunami inundation forecasts are created for 12 earthquakes with different epicenters. Among them, the maximum inundation depth (inundation) at each point is compared with the tsunami inundation forecast maps of the Keicho-type earthquake, Genroku-type Kanto earthquake, and the Kaminawa / Kokufutsu and South Kanto earthquakes, which are expected to cause great damage to Chigasaki city. Depth) is shown.
2. Probability of passing through the AR area This refers
to the ease of movement / passage of vehicles and the ease of evacuation / passage of people in each town after an earthquake. Specifically, we will measure the ease of entry of emergency vehicles into the area and the ease of evacuation of people from the area.
3. AR road blockage rate
This is a measurement of the risk of road blockage due to the collapse of roadside buildings.
Four. AR Fire risk information display Displays a
measurement of the risk of a fire breaking out from a building and spreading. The measurement results show the buildings called "clusters" that will eventually burn down if left unattended in the same color.
Five. AR Building collapse risk information display
Similarly, the collapse risk of buildings that require caution in the event of an earthquake is displayed. The risk of a building collapsing due to shaking caused by an earthquake or liquefaction of the ground is measured using data such as the structure of the building and the age of the building.
6. Liquefaction risk The risk of
liquefaction is expressed in three stages. The liquefaction risk of this application was evaluated by combining the
"land conditions" determined by the topography and the presence or absence of artificially modified land and the
"PL value" indicating the liquefaction risk obtained by calculation using the results of the geological survey . ..
[Precautions for use]
This app is not intended to be used in the event of a disaster, but is designed to be used in advance as a preparation for daily disaster prevention.
In the event of an actual earthquake or disaster, it may exceed or fall below expectations depending on the scale. Regardless of the area displayed in the app, if there is a risk of fire or collapse due to an earthquake, please act at your own risk.
