Dear Alexandre, Indeed the solution by Florian below is very nice. If you really want to go the other direction you can use `as.SpatialGridDataFrame.im()` from the `maptools` package. By the way, based on what you write, I think you mean to use the value 7.5 (=0.75m) rather than 0.75

Dear Alexandre, instead of converting the image to a SpatialPixelDataFrame converting to a raster object might be an alternative. r_pines<-raster(d_pines) writeRaster(r_pines, "Pines.tif") Regards, Florian Am 26.09.2018 um 22:25 schrieb ASANTOS via R-sig-Geo: Dear R-sig-geo Members,    

[R-sig-Geo] Create Kernel image results in *tif format

2018-09-26 Thread ASANTOS via R-sig-Geo
Dear R-sig-geo Members,     I've like to create Kernel image results as *tif using an object of density() function output in spatstat package. But in my example, doesn't work when I try: #Packages library(spatstat) library(raster) library(rgdal) #Swedishpines's data set in spatstat package
