The immersion area prediction service providing unit 130 provides an associated application for predicting immersion area to the terminal device 200. When the provided application is executed, the immersion area prediction service providing unit 130 searches the current location or the user- , Destination location) from the terminal device 200, and provides the terminal device 200 with map information corresponding to the received location information.

In addition, the immersion area prediction service providing unit 130 may use the map information displayed on the 3D map with one or more terminal devices 200 in cooperation with the geographical environment information providing apparatus 300 to determine geographical conditions affecting immersion And provide a flood forecasting service according to the identified geographical situation.

Specifically, the immersion area prediction service provider 130 receives the geographical environment information of the surrounding area within a predetermined radius from the geographical environment information providing device 300 on the basis of the detected location information as a destination, The geographical environment information can be used to analyze the weather and topographical features of the surrounding area for user's inundation prediction. For example, the flood-area prediction service provider 130 may use the topographic information collected in the surrounding area within a predetermined radius based on the detected location information to calculate the topographic state of the corresponding area, that is, the altitude and the tilt angle Can be analyzed. That is, the flood forecasting service provider 130 analyzes the altitude terrain higher than the destination and analyzes the tilt angle of the analyzed altitude terrain. Accordingly, the immersion area prediction service provider 130 can set one or more inflow paths through which water can flow into the destination using the analysis results of the altitude and the inclination angle. Here, the flood forecasting service provider 130 may analyze one or more paths from the destination to the departure place in a predetermined time unit based on the contour line and altitude information of one or more paths in the surrounding area within a predetermined radius .

The flooded area prediction service provider 130 can analyze the amount of precipitation, earthquake, typhoon, tsunami, and river / river water level using the real-time weather information collected in the surrounding area.

The flooded area forecasting service provider 130 then uses the confirmed results such as precipitation and overflow of sea / river / river, and the analyzed topographical condition results of the corresponding area, The amount of inflow of water and the inflow time (moving time) that can be detected automatically, and the risk of flooding can be predicted by calculating the risk of infiltration at the destination based on the detected result. For example, the flood-area forecasting service provider 130 sets intervals in at least one inflow path, calculates the travel time of the water for each interval using the altitude terrain, the tilt angle, the obstacle, and the distance information analyzed in the set interval , The travel time to the destination can be calculated by adding the travel time calculated for each section. Here, the immersion area prediction service providing unit 130 periodically checks the inflow amount and inflow time (moving time) of the water, for example, in units of 10 minutes, and accumulates the detected result information to measure the flooding risk . Such flooding risk measurement can be calculated as shown in Equation (1) below.

As shown in Equation (1), the flood-area forecasting service provider 130 uses the weather information included in the geographical environment information collected in the surrounding area to estimate a preset time (For example, 10 minutes), the radius to which water can flow within a predetermined time (for example, 10 minutes) based on the destination is determined, and the amount of precipitation within the determined radius, that is, Can be confirmed. Here, the flooded area forecasting service provider 130 can grasp the radius into which water can flow in a unit time period (10 minutes) set in advance and confirm the regional precipitation amount in an area within the determined radius.

Then, the immersion area prediction service provider 130 determines whether or not the water can be introduced within the predetermined amount of time before the predetermined amount of water and the set time unit cycle (for example, 10 minutes, 20 minutes, 30 minutes ... N minutes) The amount of inflow of water flowing into the destination through at least one inflow path can be calculated. Here, the amount of precipitation confirmed in an area within a radius within which the water can flow into the confirmed rainfall amount before the preset time and the set time unit cycle (for example, 10 minutes, 20 minutes, 30 minutes ... N minutes) It is the precipitation value combined with the confirmed precipitation. In this case, the flood risk measurement period is set in units of 10 minutes, but it may be set in units of 1 minute, 5 minutes, and 15 minutes. However, the first flood risk measurement should be made 10 minutes or more before the emergency situation .

Then, the immersion area prediction service providing unit 130 sets the predicted area as the immersion prediction area, generates the immersion area prediction information for the predetermined immersion area, and transmits the generated immersion area prediction information to the one or more terminal devices (200).

In addition, the immersion area prediction service providing unit 130 may preset an area having a high risk of flooding as an area of interest using the registered location information or the statically processed immersion area information from one or more terminal devices 200. In this case, the service apparatus 100 can set a flood forecast alarm for the set area of interest, regardless of the current position of the user, and can provide a flood forecast service by predicting flood risk.

In addition, the immersion area prediction service providing unit 130 may set not only the user requesting the destination for transmitting the immersion forecast information but also other users (acquaintances, guardians, SNS friends) as well as other users for the immersion forecast alarm At the same time, the immersion forecast information can be transmitted.

Meanwhile, when the terminal device 200 is moving, the immersion area prediction service providing unit 130 receives the information on the movement route, and transmits the area to be passed through the predetermined time unit on the basis of the current position of the user on the movement route to the destination For example, six intervals to pass within one hour in 10-minute increments. Here, the set interval can be set in units of time enough to evacuate the flooded area, and the interval is updated and set continuously until the terminal device 100 arrives at the destination (destination) of the moving route, The risk of flooding can be predicted.

Then, the immersion area prediction service providing unit 130 may check whether there is an area registered as an interested area in the area within the set interval, and predict the immersion risk for the area of interest if the area of interest is registered. In addition, the flood-area forecasting service provider 130 can check the geographical environment information within the set interval and predict the flood risk for the destination by automatically setting the lowest altitude as the destination within the set interval, for example. Then, the immersion area prediction service providing unit 130 can transmit the immersion prediction information of the submergence-dangerous area predicted on the movement route to the moving terminal apparatus 200. The storage unit 140 stores relevant information to provide a flooded area prediction service. Specifically, the storage unit 140 may store information related to the flooded area prediction application, map information, and may store immersion area prediction information and safety path information according to flooding risk prediction.
