I would like to initialize this variable, but I don't know how:

double[][,] globe1 = new double[3] [100,100] ; //does not work.

What I have tried:

theoretically, I would like to have something like this:
globe1[lat, long] = [3.0,6.4,7,] //as an example of one element of this array

Thank you very much for your answer.
IN fact what I was searching for is something like this:

public void fill_Vector_object()
{
double[,][] glbl = new double[3,3][];

for (int i = 0; i < 3; i++)
{
for (int j = 0; j < 3; j++)
{
glbl[i, j] = new double[3] { 0.0, 0.0, 0.0 };
}

}
}
Where I can make a correspondence of [Latitude, Longitude] {to X,Y,Z}. This works fine

see if this helps:

double[][,] glbl = new double[3][,];

double[,] temp = new double[3, 3];

double id = 0.05d; // use 0.05d so we can verify doubles are being assigned

for (int i = 0; i < 3; i++)
{
    for (int j = 0; j < 3; j++)
    {
        for (int k = 0; k < 3; k++)
        {
            temp[j,k] = id++;
        }
    }

    glbl[i] = temp;

    // put a break-point here and inspect glbl

    temp = new double[3, 3]; // must re-initialize 'temp
}

Assuming you might want to associate a name (string) with your geo-data: consider using a Class or Struct (or Tuple).
