ncdc_locations

A dataset containing identifying information as well as coordinates and elevation for each unique North American land-based weather station in the National Climatic Data Center.
Note that sites with a missing elevation in the raw data (recorded as -999.9) have been removed.
Some sites have a potentially erroneous recorded elevation of zero meters.

datasets

Easy creation and manipulation of Voronoi diagrams using 'deldir' with visualization in 'ggplot2'. Convenient functions are provided to create nearest neighbor diagrams and heatmaps. Diagrams are computed with 'deldir' and processed to work with the 'sp' framework. Results are provided in a convenient spatial data structure and displayed with 'ggplot2'. An outline can be provided by the user to specify the spatial domain of interest.
