Retired Version

This reference documents version 1.0 (a retired version) of the MapData Services Context API. This version of the API is now retired and is no longer available for use.

What is Context?

This service provides relevant contextual information for a specific location. The context API can take either a coordinate, an address or a property ID and returns meaningful data about that location.

Security

This service supports Basic Authentication.

Request

Requests to the Context service can by made either by Address components, Coordinate or property ID.

By Address Parts

https://api.nowwhere.com.au/1.0/context/address?parameters

An Address Context request supports the following parameters:

  • street - The street portion of the address, e.g. 110 Pacific Highway.
  • locality - The locality portion of the address, e.g. Greenwich.
  • postcode - The postcode portion of the address, e.g. 2065.
  • region - The region portion of the address, e.g. NSW.
  • country - The country portion of the address, e.g. Australia.

By Coordinate

https://api.nowwhere.com.au/1.0/context/latitude,longitude

A Coordinate Context request supports the following parameters (in decimal degrees):

  • latitude - The latitude portion of the coordinate, e.g. -33.825071.
  • longitude - The longitude portion of the coordinate, e.g. 151.1904.

By Property Id

https://api.nowwhere.com.au/1.0/context/property_id

A Property Id Geocode request supports the following parameters:

  • Property Id - The property id of the property parcel e.g. GANSU705290690

Response

The format of a Context response can be controlled by setting the accepts header. Currently the only supported type is XML.

XML Output

Data

Risk Frontiers - Address Risk Ratings

A national address database with natural peril risk rating information for flood, hailstorm, earthquake and cyclone; plus other relevant characteristics such as aspect, elevation above sea level and distance to shoreline. For more information on the risk rating values see Address Risk Ratings

risktype - Describes the risk data, this can be Building match, Street or Locality aggregration. The Street/Locality aggregation responses provide the minium, maximum and average value for each risk rating for that level.
