Import tiff + tfw + prj files in R -
i want import in r map have downloaded from
http://www.naturalearthdata.com/downloads/10m-raster-data/10m-natural-earth-1/
when download 3 files following extension
.tif .tfw .prj
how should read them? can read .tif file with
imported_raster=raster('ne1_hr_lc_sr_w.tif')
but colours , projection different original tif.
thanks
i looking information on topic when came across one.
it's quite normal colours appear different original tif. there color distribution or colour scheme applied on original tif isn't exported or output tif. it's user should set colour scheme or color distribution. (just in arcmap example).
i guess exported tif has no projection @ when load in r? need use information .tfw file give each pixel (row, column) coordinate. read in .tfw file assume .tfw (ascii file) this: 10.000000 0.000000000000000 0.000000000000000 -10.000000000000 137184.00000000000 180631.000000000 last 2 rows x/y coordinates of center of upperleft pixel of tif. first row tells spatial resolution is, in case 10.
so if know coordinate of center of upper pixel, coordinate of pixel (row=i, column=j) 137184+i*10, 180631+i*10).
