Help with map display

Nathan Lundholm

Posted 9 years ago

Here is my code. (* Create empty lists ) xlist={}; ylist={}; zlist={}; ( Take inputs for ECEF ) (Label[startinput];x = Input["What is the x coordinate?"]; y = Input["What is the y coordinate?"]; z = Input["What is the z coordinate?"]; AppendTo [xlist, x] AppendTo [ylist, y] AppendTo [zlist, z] (Label[errorcontrol]; again=InputString["Enter more coords? Y for yes, N for no"]; If [again=="Y", Print["Okay!"];Goto[startinput]]; If [again!="N", Print["Sorry, this is an invalid input here!"];Goto[errorcontrol]]; If [again=="N", Print["Okay."]])); ( Debugging ) Print[xlist] Print[ylist] Print[zlist] Print[x] Print[y] Print[z] ( Combine Lists ) list=Transpose[{xlist,ylist,zlist}] ( More Debugging ) Print[list] ( Put in Coordinate Form ) GeoPositionXYZ[{x, y, z}, "ITRF00"]; ( Convert to LLA ) GeoPosition[%] ( Display Map ) GeoGraphics[GeoMarker[GeoPosition[%]],GeoRange -> "World", GeoProjection -> "Robinson"] ( Display 3D Plot *) ListPointPlot3D[list, DataRange -> {{-1000000, 1000000}, {-1000000, 1000000}}] The issue is: The map only displays the very last point entered. It should show all the points but I have absolutely no idea how to convert an entire list of cartesian coordinates to latitude longitude and then display them all on the map. Thanks for the help.

Perhaps you can look at this and see how to adapt it to display multiple points on the same map points = {}; For[i = 1, i < 6, i++, point = Input["What are the {x,y,z} coordinates?"]; AppendTo[points, GeoMarker[GeoPosition[point]]]; ]; GeoGraphics[points, GeoRange -> "World", GeoProjection -> "Robinson"] Note: You enter those x,y,z coordinates inside braces, like this, {13, 25, 37} for each point

Perhaps you can look at this and see how to adapt it to display multiple points on the same map

points = {};
For[i = 1, i < 6, i++,
  point = Input["What are the {x,y,z} coordinates?"];
  AppendTo[points, GeoMarker[GeoPosition[point]]];
];
GeoGraphics[points, GeoRange -> "World", GeoProjection -> "Robinson"]

Note: You enter those x,y,z coordinates inside braces, like this,

{13, 25, 37}

for each point
