point_yx

Geometric functions point_yx function

syntax

• point_yx(Y coordinate, X coordinate, optional coordinate unit)

definition

point_yx(Y coordinate, X coordinate, optional coordinate unit) results in a two-dimensional Point Data item.

conditions

1. The value type of the Y coordinate and X coordinate data items must match with each other and with the coordinate unit:
   • uint16 data items for wpoint units;
   • int16 data items for spoint units;
   • uint32 data items for upoint units;
   • int32 data items for ipoint units;
   • float32 data items for fpoint units;
   • float64 data items for dpoint units.
2. The domain units of the Y coordinate, X coordinate and resulting data items must match.

example

attribute<fpoint> pointYX (ADomain) := point_yx(Ycoord, Xcoord, fpoint);

Ycoord	Xcoord	pointYX 1)
401331	115135	xy(115135; 401331)
399476	111803	xy(111803; 399476)
399289	114903	xy(114903; 399289)
401729	111353	xy(111353; 401729)
398696	111741	xy(111741; 398696)

ADomain, nr of rows = 5

1) since GeoDMS 20.14.0 the table view renders a point as xy(x; y), which states the coordinate order rather than leaving it to the reader; before that it showed the untagged {y, x}. See XY order.
