Hola grupo, estoy siguiendo una gu?a de la librer?a rLandsat que me la he descargado de: devtools::install_github("socialcopsdev/rLandsat") Y tras hacer los siguiente (obviamente tengo me he registrado previamente en la api correspondiente): product_id = c("LC08_L1TP_145049_20180301_20180308_01_T1", "LC08_L1TP_145049_20170330_20170414_01_T1",

...das UTM. Determino los renglones y columnas que debe de tener el raster pero cuando visualizo en un SIG me dice que no tiene referencia espacial y el tama?o de pixel es de 29.9 y no de 30 como originalmente era y eso mete ruido al modelo que estoy generando.

...classification scheme). How can I map numbers to colours with raster?

Hi all!   My question is how to colour pixels by z value in persp plot in raster package. Here is an example:     x <- seq(-1.95, 1.95, length = 30) y <- seq(-1.95, 1.95, length = 35) z <- outer(x, y, function(a,b) a*b^2) r1 <- raster(nrows=35, ncols=30, xmn=0, xmx=30, ymn = 0, ymx = 35) r1[] <- c(z) persp(r1)   There already exist some function to produce persp plot for anothe classes, but I have no idea how deal with RasterLayer object.   Thanks all!   OV [[alternative HTML version deleted]]

Hi everyone! I would like to draw a line surrounding my raster, with i want it in black, and i don't know if its possible to change the colour. A simple example is: r <- raster(nrow=30, ncol=30, xmn=0) r[]<-NA r[393:409]<-99 r[423:439]<-99 r[453:455]<-99 r[456:460]<-30 r[461:469]<-99 r[483:499]<-99 r[513:529]<-99 plot(r,col=terrain.colors(100)) plot( edge(r, type='outer')) Could anyone help me??

Dear R-Help, When plotting a raster object the origin (0,0) is placed in the center. E.g. using: library(raster) mat = matrix(runif(100),10,10) r <- raster(ncol=10, nrow=10) values(r) <- mat plot(r, main='Raster example',xlab="x",ylab="y") Does anyone know how to adjust the coordinate system? E.g. I would like to have 0,0 at the top left. My naive approach
