Map and Table Calculation

MAPROW( ) function

Returns the row number of a pixel in raster map RasterMap at a certain (X,Y) Coordinate.

Syntax

MAPROW(RasterMap, Coordinate)

Input

Output

Notes:

• Depending on the georeference of the raster map, the row number of an XY coordinate is returned.
• The coordinate system of Coordinate is automatically transformed to the coordinate system of RasterMap if Coordinate and RasterMap do not have the same coordinate system.

Tips:

• This function may be handy to use in DDE applications.
• When the definition symbol = is used, a dependent output map or dependent output column is created; when the assignment symbol := is used, the dependency link is immediately broken after the output map/column has been calculated.

Usable in

TabCalc, Simple calculators, MapCalc 

Examples

Pocket line calculator examples:

TabCalc example:

OutCol1 = MAPROW(Landuse,Coordinate)

OutCol2 = MAPROW(Tmb1,Coordinate)

Note:

As raster map Landuse uses a different georeference than raster map Tmb1, the values in output columns OutCol1 and OutCol2 are not the same
