Hereinafter, an integrated system based on a rainwater management platform using a 3D satellite photograph or a bird's eye view map will be described in detail with reference to the components of the rainwater management server 300.

The 3D topographic map generation module 321 generates a 3D topographic map of the predetermined designated area in accordance with the generation request for the 3D topographical map of the predetermined designated area selected by the administrator terminal 100 after accessing the administrator terminal 100 And stores it in the database 330 or receives a plurality of bird's pictures taken by a method such as a drone from the manager terminal 100 and stores it in the database 330 .

Then, the 3D topographic map generation module 321 sets the x, y, and z axes, which are three-dimensional coordinates, using the metadata included in the 3D satellite map for the stored 3D satellite map, A grid (Grid) formed at predetermined length intervals can be formed for each of the axes set for the axis.

The 3D topographic map generation module 321 generates coordinate values corresponding to points on the ground surface in each of the formed grid and the 3D satellite map map.

The 3D topographic map generation module 321 completes the 3D topographic map by connecting the generated coordinate values.

More specifically, the 3D topographic map generation module 321 generates coordinate values of points corresponding to the ground surface in the 3D satellite map map to generate one index line, and then, using the generated index line as a reference, By creating the isosceles in such a manner that coordinates of the same point are connected to each other. In the case of the bird's eye photograph, it is possible to convert it into a 3D topographic map by synthesizing a plurality of plane photographs through the own algorithm and creating a three-dimensional model.

That is, when the 3D topographic map generation module 321 receives only the information on the 3D satellite map provided by the satellite image map server 400 from the manager terminal 100, It is possible to complete the 3D topographic map automatically by receiving the map. Later, local governments and other municipalities can receive information on the location and volume of sewage, gutters, and can be displayed on a separate layer from the 3D topographic map.

The flow / flow rate forming module 322 generates water flow and flow rate information for the 3D topographical map generated by the 3D topographical map generation module 321.

More specifically, the flow / velocity shaping module 322 determines the lowest isosceles lane when it is sequentially increased or decreased by a preset height (z axis) in a predetermined distance (x axis, y axis) It is possible to set a valley center line including a river, a valley, a river, etc., and not only set the highest isotope to a ridge line but also contour lines connected to the same height between a valley center line and a ridge line.

The flow rate / flow rate forming module 322 can generate the 3D map map of the predetermined area using the valley center line, the ridge line, and the contour line according to the predetermined form.

That is, the flow rate / flow rate forming module 322 is configured such that the region in which the ridge line is formed from the valley center line is formed stepwise along the entire height to the first flow / And can be classified into a single house, a set building, a forest, a paddy field, a field, a road, a playground, a pond, a lawn, a flower bed, a square Quot; second compartment type classification "that can be incorporated into the impervious pavement surface, the permeable pavement surface, the aqueduct and the like and can act as the second flow / velocity formation area. Here, the first flow rate / flow velocity forming region corresponds to a setting for distinguishing the region where the flow rate and the flow velocity become larger than a predetermined magnification in comparison with the second flow rate / flow velocity forming region at the time of rainfall.

The flow rate / flow rate forming module 322 compares the rainfall absorbing ability preset in the database 130 with the partition type classification and the first to n-th (n < th > (N is a natural number of 2 or more). Here, the flow rate / flow rate forming module 322 also performs the first to m-th steps (m is an integer equal to or greater than 2 and equal to n for non-point source contamination discharge amount set in advance in the database 130 according to the division type classification Or other natural number), can be extracted for each coordinate and each type of compartment.

Then, the flow rate / flow rate forming module 322 calculates an inclination weight corresponding to one of the first to Lth steps (L is a natural number equal to or greater than 2 and equal to or different from m) with respect to the inclination of the 3D topographical map according to the division type classification (K is a natural number equal to or greater than 2 and equal to or different from n, m, k) with respect to the surface roughness coefficient or the sieving force, It can be extracted by coordinates and compartment type.

Thereafter, the flow / flow rate forming module 322 can set the flow rate and the flow rate for each coordinate and the segment type according to the rainfall weight including the rainfall amount, the rainfall intensity, the rainfall duration, and the like for the predetermined area set in advance. More specifically, the flow / flow rate forming module 322 can calculate the flow rate unit using the flow coefficient weight, the flow velocity inverse weight, and the rainfall weight according to each coordinate or zone type, and the calculation is expressed by Equation 1 . ≪ / RTI >

Depending on the rainfall amount and the rainfall intensity It is possible to extract the nonpoint source pollution emission amount by the detailed area coordinates by the detailed areas of the "first compartment type classification" and the "second compartment type classification" classified in the 3D topographical map of the preset designated area.

In other words, the amount of rainwater is determined by the rainfall intensity and the duration of rainfall, and the phenomenon of rainfall and rainfall concentrated in guerrilla formations, The simulation module 323 must operate. Particularly, the time line simulation module 323 provides a service for predicting the quantity of pollutants and how much the pollutants are gathered according to the time when the rain, which is the characteristic point of the time element, .

The design module 324 may be configured to allow the user to install each of the pitcher blocks 500 and the respective tree infiltration apparatuses 600 in coordinates having at least one flooding / flooding coordinates or source information from the administrator terminal 100 via the network 200 The simulation result is applied to the administrator terminal 100 through the network 200. The simulation result may be transmitted to the administrator terminal 100 via the network 200. [

In this case, the rainwater storage setting or the pollutant reduction setting by each of the permeable blocks 500 and the respective tree infiltration apparatuses 600 must be stored in advance in the database 330 when installed in the flooded / flooded coordinate information.

On the other hand, the design module 324 should consider the time factor as an important factor in the case of discharging pollutants according to the non-point pollution emission amount, because it has the processing ability per hour in the storage space under the permeable packaging or the storage space for the rooftop greening.
