[mapguide-users] Re: Is it possible to convert Lat and Long value to X Y (AJAX viewer)

[Greg]

I was able to do it using something Like this:

MgUserInformation userInfo = new MgUserInformation(sessionId);
        MgSiteConnection siteConnection = new MgSiteConnection();
        siteConnection.Open(userInfo);

        MgResourceService resService =
(MgResourceService)siteConnection.CreateService(MgServiceType.ResourceService);

        MgMap map = new MgMap();
        map.Open(resService, "Cid_Map");
        
        //create coord sys
        MgCoordinateSystemFactory coordFactory = new
MgCoordinateSystemFactory();
        String srsMapDef = map.GetMapSRS().ToString();
        MgCoordinateSystem mapCS = coordFactory.Create(srsMapDef);
        MgGeometryFactory geometryFactory = new MgGeometryFactory();
        MgCoordinate coordLatLon;
        MgCoordinate coordXY;
        ArrayList X = new ArrayList();
        ArrayList Y = new ArrayList();
        Response.Write("<table>");
        for (i = 0; i < lat.Count; i++)
        {
            coordLatLon =
geometryFactory.CreateCoordinateXY(Convert.ToDouble(lon[i]),
Convert.ToDouble(lat[i]));
            coordXY = mapCS.ConvertFromLonLat(coordLatLon);
            X.Add(coordXY.GetX().ToString());
            Y.Add(coordXY.GetY().ToString());
            if (i < 108)
            {
                Response.Write("<tr class='colData'><td>" + X[i] +
"</td><td>" + Y[i] + "</td></tr>");
            }
        }
        Response.Write("</table>");
