Im using Mappoint Europe and some reverse geocoding to return a collection of UK StreetAddress values based on Lat and Long coordinates however it returns the full address but only the postcode sector I would like it to return the full postcode.

I'm sure this value must be retrivable because you can search in Mappoint for the full postcode.

Has anyone any ideas

Hi,

I assume you want the full address?

I assume you use ObjectsFromPoint to get a collection of Location. You do step trought all the objects in the return valud? also be aware that not all objects in this collection are Location objects. If you not consider all this points you will loose addresses.

If I do something like this it returns full address:

Code:

            Location Loc = MP.ActiveMap.GetLocation(Lat, Lon, Alt);
            Loc.GoTo();

            FindResults StreetResults = M.ObjectsFromPoint(M.LocationToX(Loc), M.LocationToY(Loc));

            foreach (object o in StreetResults) {
                Location StreetLoc = o as Location;

                if(StreetLoc != null && StreetLoc.StreetAddress != null) {
                    Console.WriteLine("value    " + StreetLoc.StreetAddress.Value);
                    Console.WriteLine("street   " + StreetLoc.StreetAddress.Street);
                    Console.WriteLine("postcode " + StreetLoc.StreetAddress.PostalCode);
                    Console.WriteLine("city     " + StreetLoc.StreetAddress.City);
                    Console.WriteLine("---");
                    Found = true;
                }
            }

See my other reply. Very simple, just step (scan line by line) trough usa with all lat/lon coordiantes, and increment eg 5 meter. Every next line you take also 5 meter lat diff. Then filter out duplicates.

You have in your case to check for Zip instead of for StreetAddress !

On the other hand maybe it already exists and someone wants to share it ? This because I see this kind of question regulary.

StreetAddress doesn't seem to return the full postcode as was requested in the original post, it only appears to return, as the original poster said, the postcode sector eg. TN38 9

Hi,

I dont know what you mean by 'postcode sector'. Can you please clarify?

**Winwaed** · #7 (**permalink**) 01-13-2005

Wilfried,

UK postcodes are split into a hierarchical system. Sector, area, etc. I'm always forgetting which is which

Eg. "CB3 0DS".
"CB" means it is the Cambridge area (that alone makes it more natural for humans than the US zipcode system). The CB area is pretty large, and is split into smaller areas. I think central Cambridge is split into at least three.
That is then split even further to "sector". Eg. "CB3 0??"
The last two letters designate the final postcode in the sector. The Post Office claim an average of about 12 addresses per postcode, although many offices and larger locations have a dedicated postcode. Eg. CB3 0DS is Churchill College, Cambridge (and no other addresses).

I can't really help the original poster - I've also noticed that MapPoint only really works with postcode sectors. Although it sometimes recognises full postcodes correctly, it appears to be for location finding only.

Richard
