Extracts the values of all the geopoints and returns them as a vector. If the values are strings, then the result is a list of strings. A value column other than the first one can be specified either by index (1-based in Macro or 0-based in Python) or by name, e.g. values(gpt, 4) or values(gpt, 'geopotential'). See the description of the NCOLS subformat on the Geopoints page for more details of storing multiple value columns. Another syntax is to use direct indexing, e.g.
a = gpt['geopotential']
Anchor value2 value2
vector value2 ( geopoints )
Extracts the second values of all the geopoints and returns them as a vector.
Anchor value_columns value_columns
list value_columns ( geopoints )
Returns a list containing the names of just the non-coordinate value columns in the given geopoints variable.
Anchor xy_vector xy_vector
geopoints xy_vector ( geopoints, geopoints )
