Description Objects from the Class Slots Extends Methods Author(s) See Also Examples
An S4 class that represents topography over a grid of coordinates.
Objects can be created by calls of the form new("SpatialPointsTopography", ...)
, or by calls to the function SpatialPointsTopography
.
data
:Object of class "data.frame"
containing the elevation (in m), slope (in degrees) and aspect (in degrees from North) of every point.
coords
:Object of class "matrix"
with the spatial coordinates.
bbox
:Object of class "matrix"
with the boundary box.
proj4string
:Object of class "CRS"
with the projection string.
Class "SpatialPointsDataFrame"
, directly.
Class "SpatialPoints"
, by class "SpatialPointsDataFrame", distance 2.
Class "Spatial"
, by class "SpatialPointsDataFrame", distance 3.
signature(x = "SpatialPointsTopography", i = "ANY", j = "ANY", drop = "ANY")
: subsets the spatial points and associated topography; only rows (points) can be subsetted.
