The GetPointsList command returns the list of all points stored in m.

The points are sorted in the lexicographical order.

If a point does not have a string label, the empty string is assigned to it as a placeholder.

$m≔\mathrm{DataSets}:-\mathrm{Builtin}:-\mathrm{WorldMap}\left(\left[\left[0\,0\right]\,\left[0\,-1\,''Ocean''\right]\right]\right)$

$m≔\left(\begin{array}{cc}\left[\mathrm{PLOT}\left(\mathrm{...}\right)\right]& \begin{array}{c}\mathrm{A\; map\; of\; the\; world\; with\; 2\; points}\\ \mathrm{projection:\; MillerCylindrical}\end{array}\end{array}\right)$

$\mathrm{GetPointsList}\left(m\right)$

$\left[\left[0\,\mathrm{-1}\,''Ocean''\right]\,\left[0\,0\,''''\right]\right]$

$\mathrm{AddPoints}\left(m\,\left[\left[0\,1\right]\,\left[-5\,-5\,''somewhere''\right]\right]\right)$

$\left(\begin{array}{cc}\left[\mathrm{PLOT}\left(\mathrm{...}\right)\right]& \begin{array}{c}\mathrm{A\; map\; of\; the\; world\; with\; 4\; points}\\ \mathrm{projection:\; MillerCylindrical}\end{array}\end{array}\right)$

$\mathrm{GetPointsList}\left(m\right)$

$\left[\left[\mathrm{-5}\,\mathrm{-5}\,''somewhere''\right]\,\left[0\,\mathrm{-1}\,''Ocean''\right]\,\left[0\,0\,''''\right]\,\left[0\,1\,''''\right]\right]$

$\mathrm{RemovePoint}\left(m\,\left[0\,-1\,''Ocean''\right]\right)$

$\left(\begin{array}{cc}\left[\mathrm{PLOT}\left(\mathrm{...}\right)\right]& \begin{array}{c}\mathrm{A\; map\; of\; the\; world\; with\; 3\; points}\\ \mathrm{projection:\; MillerCylindrical}\end{array}\end{array}\right)$

$\mathrm{GetPointsList}\left(m\right)$

$\left[\left[\mathrm{-5}\,\mathrm{-5}\,''somewhere''\right]\,\left[0\,0\,''''\right]\,\left[0\,1\,''''\right]\right]$

The DataSets[Builtin][WorldMap][GetPointsList] command was introduced in Maple 2017.
