Map and Table Calculation

COORD( ) function

Returns (X,Y) coordinates from separate X coordinates and Y coordinates (and a coordinate system).

Syntax

COORD(X, Y)
COORD(X, Y, CoordinateSystem)

Input

Output

Notes:

• The COORD function can be used to combine separate X-coordinates and Y-coordinates into XY-coordinates.
• In coordinate calculations, you can either use:
  - a coordinate column with combined XY-coordinates;
  - the COORD function when you have 2 separate columns with X-coordinates and Y-coordinates.
• When using a LatLon coordinate system, the syntax is COORD(Lon, Lat, LatLon).
• You can produce columns that use a coordinate system as domain, but you cannot create maps that use a coordinate system as domain.
• CoordinateSystem must refer to a coordinate system in which the XY-coordinates fit (e.g. the coordinates of the point map); CoordinateSystem is not a target coordinate system; to transform coordinates to another coordinate system use the TRANSFORM function.

Tip:

When the definition symbol = is used, a dependent output column is created; when the assignment symbol := is used, the dependency link is immediately broken after the output column has been calculated.

Usable in

Simple calculators, TabCalc, MapCalc

Examples

Pocket line calculator examples:

TabCalc example:

XYCoord = COORD(X,Y,Cochabamba)

XYLatLon = TRANSFORM(XYCoord,LATLON)

XYLatLon = TRANSFORM(COORD(X,Y,Cochabamba),LATLON)

Point data from the Cochabam area currently using coordinate system Cochabamba (Cochabamba, Bolivia) will be transformed into longitudes and latitudes (LatLon coordinate system).

In words the above mentioned expressions read:

Take the X-component of a coordinate belonging to coordinate system Cochabamba and transform it to a longitude value. Take the Y-component of a coordinate belonging to coordinate system Cochabamba and transform it to a latitude value.
