Abstract:
|
The Mary Jane project includes an analysis of the slopes and other attributes of ski trails (Mary Jane/Winter Park Resort, CO) based on the USGS high resolution digital elevation model. This study provides an illustration of the statistical tools in the R package, fields, for fitting smooth curves surfaces and displaying image data. Show cased here are methods of conditional simulation that provide useful measures of uncertainty for an estimated function.
