Trillium Geocoding resolution not correct. 'Street' level geocode resolution at incorrect point – not on same street

  • 1.  Trillium Geocoding resolution not correct. 'Street' level geocode resolution at incorrect point – not on same street

    Posted 03-27-2023 08:31

    We are currently using Trillium as a geocoding provider for a few of our clients.
    One of our clients have raised geocoding queries that the address supplied is complete but accuracy returned is "street" and coordinate is also at wrong place.

    For example, if we geocode the addresses-   20 Fenchurch St, London   &   20 Fenchurch St, London, EC3M 3BY
    the lat long which we receive, if we check them on google maps, are actually few miles apart.

    • When we supply only address without postcode, i.e. 20 Fenchurch St, London, then the latitude longitude received is 51.517257, -0.091353
    • When we supply post code along with address i.e. 20 Fenchurch St, London, EC3M 3BY, then the latitude longitude received is 51.511600, 0.000000

    if we check them on google maps, both co-ordinates are actually few miles apart.

    Attached are the request (without 'username' & 'password' tag) & response for the input address without postcode & with postcode

    Kindly suggest.
