aRTtheme {aRT} | R Documentation |
Class that enables database queries with temporal and (or) attribute restrictions. It can select the objects from the ids resulting from a spatial query.
Themes in TerraLib can have visual aspects, as colors and lines styles. These
configurations are not used when an aRTtheme
object is created, besause it
can be used only for data processing. But there are functions to do so, for example
setVisual
and setVisible
.
Objects can be created by calling createTheme
or openTheme
, from aRTlayer
.
openTheme
is a function of class aRTdb
too.
Class aRTcomponent
, directly.
