Riskmap distribution - mapserv.riskmap

Obtains risk contour vector data of risk maps.

JSON-RPC v2.0 is used as the execution method.

Sample Request

{
  "jsonrpc": "2.0",
  "method": "mapserv.riskmap",
  "params": {
    "type": "Feature",
    "geometry": {
      "type": "Polygon",
      "coordinates": [[
          [139.25, 35.25], [139.25, 35.5], [139.625, 35.5],
          [139.625, 35.25], [139.25, 35.25]

      "themes": ["riskmap_fujisawa"]
    }
  },
  "id": "mapserv_riskmap"
}

Parameter

Request parameters are described in GeoJSON Feature format.

Geometry is a spatial region to be searched for. The type can be Polygon, Line, Point, or Collection of these.

For Properties, specify the following parameters:

Parameter Name	Data Type	Details	Default Value
start_datetime	string	Date and Time ("YYYY-MM-DD hh:mm:ss+TZ")	Required
end_datetime	string	Date and Time ("YYYY-MM-DD hh:mm:ss+TZ")	start_datetime + 1 seconds
themes	[string, [string,...]	Target risk map	Required
target_theme_mesh_degree	int	Mesh degree of Target risk map	optional (1~5)

Return Values

GeoJSON (FeatureCollection) is returned. Each record of event data is stored as a Feature.

Each feature's geometry is the GeoJSON representation of the geom. In the properties, the risk map name will be stored in theme, the risk value in risk and the datetime in datetime.

Description

Obtains risk contour polygon data of risk maps.

Returns the risk polygon contour data in the period specified by start_datetime and end_datetime and in the map(s) specified by themes that intersect the region(s) specified in the geometry part of the request GeoJSON.

When the target period, number of target risk maps and geometry parts are large, an extremely large GeoJSON may be returned.

This API returns only risk values in addition to the spatio-temporarl attributes. Use Prediction map distribution API when other attributes values are needed.

If the request includes target_theme_mesh_degree, the risk map for the most recent time since the time specified in start_datetime will be returned.
