tclgeomap_procs package

The tclgeomap_procs package supplements the tclgeomap package with additional procedures written in Tcl. Here is a brief description of each procedure. Full details are in the tclgeomap_procs man page.

geomap::latitude returns the latitude element of a {latitude longitude}
geomap::longitude returns the longitude element of a {latitude longitude}
geomap::latlon returns the decimal representation of a point, converting from degree minute second format if necessary.
geomap::circle makes a list of points on a circle
geomap::fillsegment makes a list of points on the great circle connecting two points
geomap::grid_list makes a set of grid lines
geomap::ocean_list makes a set of polygons that cover the Earth, good for initializing a map.

Here are some usage examples.

tclsh$ package require tclgeomap_procs 2
2.0
tclsh$ set latlon {-40.0 -100.0}
-40.0 -100.0
tclsh$ geomap::latitude latlon
latlon not a {latitude longitude}
while evaluating {geomap::latitude latlon}
tclsh$ geomap::latitude $latlon
-40.0
tclsh$ geomap::longitude $latlon
-100.0
