Geocode

You can geocode any address using the SmartMaps-API, as well as assign an address to a coordinate.

Ressource  Path

The functionality is provided via a classic REST interface, which can be accessed via the following link:

POST https://www.yellowmap.de/api_rst/v2/geojson/geocode?systemPartner=XXXX&securityID=XXXX

Authentication

To use the interface, you need a partner name and an access key. You get both from YellowMap. For authentication, the partner name and the security key are each passed as GET parameters.

Parameter Description
systemPartner Partner name – given from YellowMap.
securityId Security key – given from YellowMap.

Parameter

The parameters are included in the body, of the POST request as JSON.

Geocode (address / search string to geographic coordinate)

You can use the type "geocodingType": "GEOCODE" to geocode a geographic coordinate in the form of a location object (address) or a search string.

{
    "type": "Feature",
    "properties": {},
    "geometry": {
        "type": "Point",
        "coordinates": [
            0,
            0
        ]
    },
    "crs": {
        "type": "name",
        "properties": {
            "name": "urn:ogc:def:crs:OGC:1.3:CRS84"
        }
    },
    "searchparams": {
        "geocodingType": "GEOCODE",
        "coordFormatOut": "GEODECIMAL_POINT"
    },
    "authentication": {
        "channel": "Test123"
    },
    "location": {
        "country": "DE",

        "street": "CAS-Weg",
        "houseNo": "",
        "singleSlot": ""
    }
}

Reverse Geocode (geographic coordinate to address)

You can use the type "geocodingType": "REVERSE_GEOCODE" to geocode an address in the form of a geographic coordinate.

{
    "type": "Feature",
    "properties": {},
    "geometry": {
        "type": "Point",
        "coordinates": [
            8.439451304332795,
            49.021658248904146
        ]
    },
    "location": {},
    "crs": {
        "type": "name",
        "properties": {
            "name": "urn:ogc:def:crs:OGC:1.3:CRS84"
        }
    },
    "searchparams": {
        "geocodingType": "REVERSE_GEOCODE",
        "coordFormatOut": "GEODECIMAL_POINT"
    },
    "authentication": {
        "channel": ""
    }
}
