Abstract:
|
Virtual earth browsers such as Google Earth offer an alternative medium for presenting spatial-temporal data that breaks from traditional static plots and has the potential to transform geographical information visualization. The interface makes it easy for the user to interact with a visualization and to bring in additional auxiliary information, such as geographic features, political boundaries, and others' data. With its built-in controls to layer, annotate, and animate information, virtual-earth browsers present an exciting opportunity for reaching broad audiences. We describe how to use RKML, an R package, to create Google Earth displays of climate data. We present three models for creating these displays: one is analogous to the traditional approach used in R to add points to a data region; another extends the formula language syntax in R to encompass geo-spatial and temporal concepts; and the
