Big thanks to all the respondents for their help with my problem last week.
Based on their suggestions it seems that the way to solve my problem is to use
the following commands:
gp <- gridparameters(obj)
gp <- round(gp,3)
GT <- with(gp, GridTopolopy(cellcentre.offset, cellsize, cells.dim))
obj
Hi,
why don't you do:
temp<- as.data.frame("your grid")
temp$lon <- round(temp$lon, 3)
temp$lat <- round(temp$lat, 3)
"your grid" <- temp
coordinates("your grid") <- ~lon+lat
gridded("your grid") <- TRUE
This can be done with less command lines, just wanted to make the
interpretation easier.
Probably the best way to do this is to modify the GridTopology and
recreate the grid.
The coordinates of a SpatialGridDataFrame are calculated from the 6
values of the grid topology, only SpatialPixelsDataFrame stores every
cell coordinate (possibly sparsely).
It's best to recreate the object, ot
Hi there,
I have a SpatialGridDataFrame object and I wish to round the coordinates
associated with the grid to three decimal places in order to match points in
this object with points on another spatial object where the coordinates are
recorded to three decimal places.
Some information about
