Description

An S4 class that represents topography that has locations on a regular grid.

Objects from the Class

Objects can be created by calls of the form new("SpatialPixelsTopography", ...), or by calls to the function SpatialPixelsTopography.

Slots

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.

Extends

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.

Methods

[

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.

spplot

signature(object = "SpatialPixelsTopography"): allows plotting topography maps.
