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”)

   Expr = readmap(“Expr.map”)

   Result = xcoordinate(Expr)

   Result.map	Expr.map
