ShapeFileFeatureLayer MyworldLayer = new ShapeFileFeatureLayer(worldLayerFilePath) String worldLayerFilePath = Directory.GetParent(Directory.GetParent().FullName).FullName + '\SampleData\Dar_Ward.shp' Thank you for the reply. I have obtained one point from within Dar_Ward shape file and entered it into my custom database and then plot it by creating a layer that overlays with Dar_Ward layer. The point still does not show. The following is the coordinates for that point. Map1.CurrentExtent = Layer1.GetBoundingBox() LayerOverlay staticOverlay = new LayerOverlay('StaticOverlay') Layer1.DrawingQuality = DrawingQuality.HighSpeed = AreaStyles.CreateSimpleAreaStyle(GeoColor.FromArgb(150,), GeoColor.FromArgb(100, )) ShapeFileFeatureLayer Layer1 = new ShapeFileFeatureLayer(Server.MapPath('~/App_Data/dar_ward.shp')) WorldMapKitWmsWebOverlay worldMapKitWmsOverlay = new WorldMapKitWmsWebOverlay() Map1.MapUnit = GeographyUnit.DecimalDegree = new GeoSolidBrush(GeoColor.FromHtml('#E5E3DF')) I looked at that new data you just send and the projection information found in the PRJ file seems to match. I applied projection conversion to that shapefile so that it aligns with the World Map Kit in Geodetic (Longitude/Latitude) and it goes to Tanzania, near Dar Es Salam. Is it where it is supposed to go? Gets the Longitude and Latitude in the format of your GPS device reads.

string Latitude = DecimalDegreesHelper.GetDegreesMinutesSecondsStringFromDecimalDegree(GEOpointShape.Y) string Longitude = DecimalDegreesHelper.GetDegreesMinutesSecondsStringFromDecimalDegree(GEOpointShape.X) To have the longitude and latitude in the format of your GPS device reads, simply use the X and Y properties of the PointShape, as you can see in the code snippet below:

Proj4.ExternalProjectionParameters = ManagedProj4Projection.GetEpsgParameters(4326) Proj4.InternalProjectionParameters = ManagedProj4Projection.GetEpsgParameters(32737) InMemoryMarkerOverlay inMarkerOverlay = new InMemoryMarkerOverlay('markerOverlay', columns) įeature feature = new Feature(double.Parse(item.ToString()), double.Parse(item.ToString())) įoreach (DataColumn col in datatable.Columns)įeature.ColumnValues = item.ToString() I still have problem with projection. My image is in WGS 84 / UTM zone 37S and when I plot the points from my GPS device they don't match. My code is as shown below String Latitude = DecimalDegreesHelper.GetDegreesMinutesSecondsStringFromDecimalDegree(GEOpointShape.Y)

String Longitude = DecimalDegreesHelper.GetDegreesMinutesSecondsStringFromDecimalDegree(GEOpointShape.X) Used the DecimalDegreesHelper static functions to format the Longitude and Latitude values. PointShape GEOpointShape = (PointShape)proj4.ConvertToExternalProjection(UTMpointShape) PointShape UTMpointShape = new PointShape(e.Position.X, e.Position.Y) Converts from UTM to Geodetic to get the values for Longitude (.X) and for the Latitude (.Y) Proj4.ExternalProjectionParameters = ManagedProj4Projection.GetEpsgParameters(4326) //Geodetic WGS 84 /ref/epsg/4326/ The projection you want to get the values in (Longitude/Latitude) Proj4.InternalProjectionParameters = ManagedProj4Projection.GetEpsgParameters(3160) //UTM zone 16 /ref/epsg/3160/ ManagedProj4Projection proj4 = new ManagedProj4Projection() Protected void Map1_Click(object sender, MapClickedEventArgs e) Let say, for example, that your map is in the zone 16 UTM, look at the code in the Click event of the Map to get the coordinates for the Longitude and Latitude:
