Pregunta sobre rLandsat
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",

Pregunta sobre rLandsat
Hola Ángel:
Yo creo que tendrías que establecer el sistema de coordenadas de
referencia de tu objeto raster antes de salvarlo como GTiff. Algo así:
crs(r1) <-"+proj=utm +zone=14 +datum=WGS84"
Saludos,
Marcelino.

geotiff or tiff files with world files
Hi,
I have a matrix of data which i can vizualize as an image - for example. I would like to save this image as a geotiff file or at a tiff file with a world file which holds the projection of my data (ultimately the data represent a map of some sort). I know i can save the data as an ESRI grid, but i am not interested in that.
I wonder if anybody knows about any code which will help me do

Problems of exporting raster to ArcGIS
...I used function writeRaster{raster} to write this rasterLayer into every format it supports, and ArcGIS respond to them in three different ways, but none of them works. I wonder why it happens and if there is someway to solve this problem?
ArcGIS respond type:
1. Show strange values
GTiff, HFA
2. Show even values in whole raster
IDRISI, ascii, EHdr
3. Cannot recognize files
CDF, raster, SAGA, CDF , ENVI

write geotiff with projection - RGDAL package
...y code follows:

I will really appreciate if anybody can point me in the right dirrection.

Problem in calling R functions from Matlab
...;> [a b c] = evalR('img <- readGDAL("testimg_p.tif")')
a = ?????[]
b = ?????0
c = Invoke Error, Dispatch Exception: Object is static; operation not allowed
The command works from R prompt:
> img <- readGDAL("testimg_p.tif")
testimg_p.tif has GDAL driver GTiff
and has 280 rows and 272 columns
It is giving same error while loading gstat library:
>> [a b c] = evalR('library(gstat) ')
a =???? []
b =???? 0
c = Invoke Error, Dispatch Exception: Object is static; operation not allowed
I guess the error is not related to readGDAL or gstat l...
