MapForums

Hi,

My company has a product called ULTRATRACK, it can track any object like vehicles, marines, planes etc. Each unit will send me the latitude and longitude received through a GPS antena. So i need the reverse geocoding inorder to find out the location.

I tried the OCX of two other company and those are not satified me. But those have routines to find out the address ( block, street, city, state and zip code) from a latitude and longitude.

MapPoint 2002 has a routine to point out specified latitude and longitude on a map.

I wish to get some routine which can return the address also. This is a major requirement to use mappoint with our application. Hope i can have some routines in the new version of mappoint.

Thanks
joe

There are some techniques for reverse geocoding with MapPoint, see three articles on this web site.. but note that reverse geocoding is not a supported feature in MapPoint, the techniques are hacks and not ideal.

Hi Eric,

Here is one old Q & A related to Reverse Geocoding.

http://www.mp2kmag.com/mappointqa.asp?p=users&id=399

I tried the same thing to implement in Delphi. I couldnt get all properties.

Here is my piece of code. I put the TApplication Component on the form.

procedure TForm1.SpeedButton1Click(Sender: TObject);
Var
Addr : String;
Loc : Location;
oResult : FindResults;
FMap : _map;
begin
FMap := Application1.ActiveMap as _Map;
Loc := FMap.GetLocation(40.778, -124.1827,1) as Location;
Loc.GoTo_;
oResult := FMap.ObjectsFromPoint(FMap.LocationToX(Loc),FMap.L ocationToY(Loc)) as FindResults;

end;

In VB they are declaring variable FMap as MapPoint.Application. How we can delcare that variable. I used the TApplication instead of that.

Thanks,
joe
