Here is my code:
(* Take inputs for ECEF *) x = Input[“What is the x coordinate?”]; y = Input[“What is the y coordinate?”]; z = Input[“What is the z coordinate?”];
(* Put in Coordinate Form *) GeoPositionXYZ[{x, y, z}, “ITRF00”];
(* Convert to LLA *) GeoPosition[%]
(* Display Map *) GeoGraphics[GeoMarker[GeoPosition[%]],GeoRange → “World”, GeoProjection → “Robinson”]
It lets me input coordinates for one point in ECEF, then converts it to latitude/longitude/height and shows it on a map.
I want to keep showing the 2d map… but I also want to show a 3d globe that locates the coordinates on the 3d cartesian plane also.
I need to be able to put in more than one coordinate. It needs to keep asking for more x’s, more y’s, more z’s… until I stop inputting them. Eventually it’s going to be modified to pull them out of a text file, but for now these two changes need to be made. Any ideas/hints/help/guidance is appreciated. Thanks.
Hint for the second part of your question: Look up While in the help system. Could that do something for you?
That might actually be helpful… if there was anyway for anyone other than a rocket scientist to understand how to create empty lists in the first place… I’ve read the entry for lists a trillion times and the only lists that seem possible to make are prepopulated by hardcoded data.

If I want 3 lists will xlist={} and ylist={} and zlist={} work?
Figuring out how programming works is a real hurtle.
Figuring out how Mathematica progamming works can be a hurtle on top of two other hurtles.
For your lists, what about something like this inside your While
{GeoGraphics[GeoMarker[GeoPosition[{x, y, z}]], GeoRange -> "Country"],
GeoGraphics[GeoMarker[GeoPosition[{x, y, z}]], GeoRange -> "World", GeoProjection -> "Robinson"]
}
but this is doing things with new parts of Mathematica that I’ve never even seen before.
Right now I need to learn how to manipulate the lists in the first place.
How do I add new x value to xlist?
Is it Append[xlist, x] ?
Also, how do I read back all the contents of a list?
Please don’t stop helping me.
I give up. Mathematica, please give me a refund. I’m dropping out of school because I have no future in this line of work. I don’t have an IQ of 500000 so I’ll never be able to learn Mathematica.
