Description Objects from the Class Slots Extends Methods Author(s) See Also Examples
An S4 class that represents topography that has locations on a regular grid.
Objects can be created by calls of the form new("SpatialPixelsTopography", ...)
, or by calls to the function SpatialPixelsTopography
.
data
:Object of class "data.frame"
containing the elevation (in m), slope (in degrees) and aspect (in degrees from North) of every cell.
coords.nrs
:Inherited from SpatialPointsDataFrame
but not used.
grid
:Object of class GridTopology
.
grid.index
:Index of points in full grid.
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 "SpatialPixelsDataFrame"
, directly.
Class "SpatialPixels"
, by class "SpatialPixelsDataFrame", distance 2.
Class "SpatialPointsDataFrame"
, by class "SpatialPixelsDataFrame", distance 2.
Class "SpatialPoints"
, by class "SpatialPixelsDataFrame", distance 3.
Class "Spatial"
, by class "SpatialPixelsDataFrame", distance 4.
signature(x = "SpatialGridTopography", i = "ANY", ..., drop = "ANY")
: subsets the pixels and associated topography; only one dimension can be subsetted. If drop = TRUE
the boundary box is recalculated.
signature(object = "SpatialPixelsTopography")
: allows plotting topography maps.
