Copied from codeplex issue 63640:

Hello Guys,

I have a problem while reprojecting from UTM (MGI / Austria GK West) to WGS84 (Lat/Lon), I have an error of about 500 m in Latitude and 50 m in Longitude, thats my VB.net code:

' lines
Sub processLines(fs As IFeatureSet)

    ' set EPSG code
    fs.Projection.AuthorityCode = 31254

    '  Destination projection information
    Dim dest As DotSpatial.Projections.ProjectionInfo = KnownCoordinateSystems.Geographic.World.WGS1984
    dest.GeographicInfo = fs.Projection.GeographicInfo

    ' set EPSG code
    dest.AuthorityCode = 4326

    ' reproject
    fs.Reproject(dest)

I´m using Qgis to echeck the results. Thanks in Advance!

Oliver
