I have points as geometry format in table that I use for some analysis. All points are saved in four dimensions eg. x, y, z and m - lon, lat, alt and time. The issue is that for the analysis are used functions like ST_GeomFromEWKT and ST_MakeLine, which included only two dimensions form the four present.
My specific questions is can I have the four dimensions using these functions?
I tried simple example
SELECT ST_AsText(ST_MakeLine(ST_MakePoint(1, 1, 0, 1339590840), ST_MakePoint(2, 2, 0, 1339590840)));
Which returns "LINESTRING(1 1,2 2)", without z and time dimensions.
Thanks in advance!
