SpatialVectorsSimulations-class: A class for spatial simulations containing equiprobable line, point or polygon features

Description

A class containing input and output maps generated as equiprobable simulations of the same discrete object (for example multiple realizations of stream networks). Objects of this type can be directly visualized in Google Earth by using the plotKML-method.

Examples

## load a list of equiprobable streams:
data(barstr)
data(bargrid)
library(sp)
coordinates(bargrid) <- ~ x+y
gridded(bargrid) <- TRUE
## output topology:
cell.size = bargrid@grid@cellsize[1]
bbox = bargrid@bbox
nrows = round(abs(diff(bbox[1,])/cell.size), 0) 
ncols = round(abs(diff(bbox[2,])/cell.size), 0)
gridT = GridTopology(cellcentre.offset=bbox[,1], cellsize=c(cell.size,cell.size), 
  cells.dim=c(nrows, ncols))
## derive summaries (observed frequency and the entropy or error):
bar_sum <- count.GridTopology(gridT, vectL=barstr[1:5]) 
## NOTE: this operation can be time consuming!
## plot the whole project and open in Google Earth:
plotKML(bar_sum, grid2poly = TRUE)
