How to display routes on OpenStreetMaps from richtextbox data, how create list which two value from another array? - arrays

Question

I have this function which get back longitude and latitude from my Rtb data (first picture):
// funkcja pobierająca szerokość i długość geograficzną w formacie dziesiętnym
private Tuple<double, double>[] wsp_geograficzne(string[] lines)
{
return Array.ConvertAll(lines, line =>
{
string[] elems = line.Split(',');
return new Tuple<double, double>(0.01*double.Parse(elems[1]), 0.01*double.Parse(elems[3]));
});
}
This line calls this above function:
var data = wsp_geograficzne(richTextBox1.Lines);
This is a sample, which display routes on my OpenStreetMaps.
GMapOverlay routes = new GMapOverlay(gMapControl1, "routes");// Constructing object for Overlay
gMapControl1.Overlays.Add(routes);
List<PointLatLng> list = new List<PointLatLng>(); // The list of Coordinates to be plotted
list.Add(new PointLatLng(53.119149707703, 23.1447064876556));
list.Add(new PointLatLng(53.11963262556597, 23.1468522548676));
list.Add(new PointLatLng(53.1205276192621, 23.1460046768188));
list.Add(new PointLatLng(53.120701464779, 23.1463050842285));
list.Add(new PointLatLng(53.1200962217943, 23.1489872932434));
list.Add(new PointLatLng(53.1196970143107, 23.1489014625549));
list.Add(new PointLatLng(53.119439459128, 23.1490087509155));
GMapRoute r = new GMapRoute(list, "myroute"); // object for routing
r.Stroke.Width = 5;
r.Stroke.Color = Color.Blue;
routes.Routes.Add(r);
gMapControl1.ZoomAndCenterRoute(r);
gMapControl1.Zoom = 15;
It looks like on the picture:
I want display routes from my data "wsp_geograficzne" (wsp_geograficzne include longitude and latitude) on this map. How should I do it? Is there any method that allow me to create List which data from "wsp_geograficzne"? I trying something like this:
List<PointLatLng> nowa = new List<PointLatLng>();
foreach (var p in data)
nowa.Add(p.Item1, p.Item2);
but it dont works. I get back error: Error 2 No overload for method 'Add' takes 2 arguments.
Please help :)

Answer 1

Ok I find answer (new function which get back 2 value (longitude and latitude) from rtb (longitude and latitude are back in decimal notation):
// funkcja pobierająca szerokość i długość geograficzną w formacie dziesiętnym
private Tuple<double, double>[] wsp_geograficzne(string[] lines)
{
return Array.ConvertAll(lines, line =>
{
string[] elems = line.Split(',');
double we1 = 0.01 * double.Parse(elems[3], EnglishCulture);
int stopnie1 = (int)we1;
double minuty1 = ((we1 - stopnie1) * 100) / 60;
double szerokosc_dziesietna = stopnie1 + minuty1;
double we2 = 0.01 * double.Parse(elems[5], EnglishCulture);
int stopnie2 = (int)we2;
double minuty2 = ((we2 - stopnie2) * 100) / 60;
double dlugosc_dziesietna = stopnie2 + minuty2;
return new Tuple<double, double>(szerokosc_dziesietna, dlugosc_dziesietna);
});
}
And this is a part which display routes on the map.
{
var data = wsp_geograficzne(richTextBox1.Lines);
List<PointLatLng> nowa = new List<PointLatLng>();
foreach (var p in data)
nowa.Add(new PointLatLng(p.Item1, p.Item2));
GMapOverlay routes = new GMapOverlay(gMapControl1, "routes");
gMapControl1.Overlays.Add(routes);
GMapRoute r = new GMapRoute(nowa, "myroute"); // object for routing
r.Stroke.Width = 9;
r.Stroke.Color = Color.Blue;
routes.Routes.Add(r);
gMapControl1.ZoomAndCenterRoute(r);
gMapControl1.Zoom = 16;
}
If someone has another notations this part:
List<PointLatLng> nowa = new List<PointLatLng>();
foreach (var p in data)
nowa.Add(new PointLatLng(p.Item1, p.Item2));
please show me here.
