Label Expression access to SHAPE

TylerT — Sun, 14 May 2023 14:05:47 GMT

Hello,

It dawned on me that Label Expressions do not have access to the SHAPE column. It would be nice to write (pseudo code): SHAPE.area(), SHAPE.len(), etc directly...ie. not add/calc new area and length columns. Any thoughts or workarounds on this topic? Thx.

Switch to Arcade, it has those options.

var a = Area($feature) var p = Length($feature) var v_num = Count(Geometry($feature).rings[0]) var v0 = Geometry($feature).rings[0][0] var lines = [ v_num + " vertices", "first vertex: " + Round(v0.x, 1) + " / " + Round(v0.y, 1), "area: " + Round(a, 1) + " m²", "perimeter: " + Round(p, 1) + " m", ] return Concatenate(lines, TextFormatting.NewLine)

Where are you trying to write the label expression? I see these fields and am able to utilize them in label expression in 2.9.3 and 3.1.1.
