I am trying to change MODIS data's (LAI) sinusoidal projection to geographic. Actually I did it. But when I reproject it by ERDAS, the output LAI raster moved about 10 km to west side of actual shapefile and I tried it by ENVI, the output raster also moved about 20 km but to north side of shapefile. I am using the shapefile to check accuracy of the output raster. It was shape of lake.
Also I have tried it in R to convert projection using following script
library(sp) library(rgdal) library(raster) Sys.setenv(TZ='GMT') lai_real <-raster("E:\\LAI\\LAI_hdf\\MOD15A2_LAI_2014\\New Folder\\mod15a2.a2014169.h23_26.img") projection(lai_real) <- CRS("+init=epsg:4326") writeRaster(lai_real, filename="E:\\LAI\\LAI_hdf\\MOD15A2_LAI_2014\\New Folder\\mod15a2.a2014169.h23_26_geo.img", datatype='FLT8S', overwrite=TRUE)
But it doesn't work.
How can I convert the projection of the LAI from sinusoidal to geographic (lat/long)?
