Dear all,
Hope everyone is keeping safe.
I am trying to extract/read VIIRS nighttime lights data but the output
seems rather strange.
I have uploaded the file here
<https://drive.google.com/open?id=1zpqXJ8AlEcnk6ApRb75tfQc4-Y8AfK5h> so as
not exceed the size limit of the email.
## Code ##
library(ncdf4)
library(rgdal)
netcdf_file <- c("VNP02DNB_NRT.A2020069.1048.001.nc
<http://vnp02dnb_nrt.a2020069.1048.001.nc/>")
nl <- brick(netcdf_file, lvar=0, values=TRUE,
varname="observation_data/DNB_observations")
## Detail ##
class : RasterLayer
dimensions : 3232, 4064, 13134848 (nrow, ncol, ncell)
resolution : 1, 1 (x, y)
extent : 0.5, 4064.5, 0.5, 3232.5 (xmin, xmax, ymin, ymax)
crs : NA
source : C:/Users/shour/Desktop/VNP02DNB_NRT.A2020069.1048.001.nc
<http://vnp02dnb_nrt.a2020069.1048.001.nc/>
names : DNB.observations.at.pixel.locations
zvar : observation_data/DNB_observations
The spatial resolution is supposed to be 750m but this shows 1?. What am I
doing wrong? Any help will be greatly appreciated. Thank you.
