The Trend surface operation can be directly executed by typing one of the following expressions on the command line of the Main window:
|
OUTMAP |
= |
MapTrendSurface(InputPointMap, Georeference, SurfaceType) |
|
OUTMAP |
= |
MapTrendSurface(PointMap.Column, Georeference, SurfaceType) |
where:
|
OUTMAP |
is the name of the output raster map. |
|
MapTrendSurface |
is the command to start the Trend surface operation. |
|
InputPointMap |
is the name of the input point map with a value domain. |
|
PointMap.Column |
is the name of an input point map with a class or ID domain which has a linked attribute table, and the name of a value column in this attribute table. |
|
Georeference |
is the name of an existing georeference that should be used for the output raster map. |
|
SurfaceType |
is the parameter which specifies the function with which a surface should be calculated; use one of the following: Plane | Linear2 | Parabolic2 | 2 | 3 | 4 | 5 | 6 |
When the definition symbol = is used, a dependent output map is created; when the assignment symbol := is used, the dependency link is immediately broken after the output map has been calculated.
