# xcoordinate¶

xcoordinate

X-coordinate of each Boolean TRUE cell

Result = xcoordinate(expression)

expression
spatial, non spatial boolean
Result
spatial scalar

## Options¶

--unittrue or --unitcell

--unittrue
coordinates are expressed in true distance coordinates (default)
--unitcell
coordinates are expressed in unit cell lengths, where the minimumnx coordinate of a cell centre is 0.5 and the maximum x coordinate of a cell centre is xn- 0.5, where x is the number of columns of cells.

assignment of coordinates

--coorcentre
for each cell, the coordinate of the cell centre is assigned (default)
--coorul
for each cell, the coordinate of the upper left corner is assigned
--coorlr
for each cell, the coordinate of the lower right corner is assigned

## Operation¶

For each cell that has a value 1 (TRUE) on expression assigns the x coordinate of the cell to the cell on Result. Cells with a value 0 (FALSE) on expression are assigned a missing value.

## Notes¶

A cell with a missing value on expression is assigned a missing value on Result.

## Group¶

This operation belongs to the group of Coordinates, unique ID’s

## Examples¶

1. • pcrcalc
#! –coorlr
binding
Result = Result.map;
Expr = Expr.map;
initial
report Result = xcoordinate(Expr);

• python
setglobaloption(“coorlr”)
