Sub-map of point map

Command line

The sub-map of point map operation can be directly executed by typing the following expression on the command line of the Main window:

  

OUTMAP

=

PointMapSubMap(InputPointMap, minX, minY, maxX, maxY)

OUTMAP

=

PointMapSubMap(InputPointMap, minLon, minLat, maxLon, maxLat)

where:

OUTMAP

is the name of your output point map.

PointMapSubMap

is the command to start the sub-map of point map operation.

InputPointMap

is the name of the input point map.

minX

minimum X-coordinate of output point map, i.e. X-coordinate of lower left corner (real number).

minY

minimum Y-coordinate of output point map, i.e. Y-coordinate of lower left corner (real number).

maxX

maximum X-coordinate of output point map, i.e. X-coordinate of upper right corner (real number).

maxY

maximum Y-coordinate of output point map, i.e. Y-coordinate of upper right corner (real number).

When the coordinate system of the input point map is a coordinate system of type latlon:

minLon

minimum Longitude of output point map, i.e. Longitude of lower left corner (real number, signed decimal degrees). Use a - sign when working in the Western hemisphere.

minLat

minimum Latitude of output point map, i.e. Longitude of lower left corner (real number, signed decimal degrees). Use a - sign when working on the Southern hemisphere.

maxLon

maximum Longitude of output point map, i.e. Longitude of upper right corner (real number, signed decimal degrees).

maxLat

maximum Latitude of output point map, i.e. Latitude of upper right corner (real number, signed decimal degrees).

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.
