#1

Hi,

According to the coordinates, Mszczonowska street is at 52.132839559508824, 20.891170983827966.
(Mszczonowska, 05-090 Janki, Poland
Latitude: 52.13284 | Longitude: 20.891171), but I can’t get this location by entering pointshape in the code below.

In addition, I am trying to draw a line based on the following data, also does not get the expected result on screen.

“\ColdFront1.txt”
LINESTRING (52.132839559508824 20.8911709838279696.52.13277891365223 20.891067296445456.52.13271766617681 20.89096031310927)

@code {
MapView map;
Collection serverUris = new Collection { new Uri(“http://ows.mundialis.de/services/service”) };
Dictionary<string, string> parameters = new Dictionary<string, string>
{
{ “layers”, “OSM-WMS”},
{ “STYLE”, “default”},
{ “CRS”,“4326”}
};

private List<StylingModel> stylings;
private string accessId = Guid.NewGuid().ToString();
GeoCollection<Layer> Layers = new GeoCollection<Layer>();

protected override void OnInitialized()
{
    string baseDirectorybaseDirectory = Path.Combine(Directory.GetCurrentDirectory(), "Data");

    LineStyle lineStyle = LineStyle.CreateSimpleLineStyle(GeoColors.Black, 2, false);

    InMemoryFeatureLayer inMemoryFeatureLayerColdFront = new InMemoryFeatureLayer();
    inMemoryFeatureLayerColdFront.ZoomLevelSet.ZoomLevel01.CustomStyles.Add(lineStyle);
    inMemoryFeatureLayerColdFront.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;

    StreamReader s = new StreamReader(baseDirectorybaseDirectory + @"\ColdFront1.txt");

    LineShape lineShape2 = new LineShape(s.ReadLine());
    inMemoryFeatureLayerColdFront.InternalFeatures.Add(new Feature(lineShape2));

    Layers.Add("ColdFront", inMemoryFeatureLayerColdFront);
}

}

Thanks for answers
