Dear Vikram,
I have update the RemoteSensing package in order to easily compute the DN to
reflectance conversion.
For Unix system you should be able to update RemoteSensing to 0.4.2 with this
updates. On Windows you have to wait a little more.

Dear Matteo,
I work on windows, but I calculated the NDVI from on sensor reflectance
(toa reflectance) with 'Landsat' package.
I already try the 'RemoteSensing' package and really liked it. Though I
am waiting for windows version of this package.
I found this bit easier than 'landsat' package.
Matteo,
by RemoteSensing package you mean the landsat package?

Dear Vikram,
It is not good to calculate NDVI from DN. The purpose of DN (digital
number) is only for packing as much information as possible into a given
“BIT-size”
Hi Agus,
no I mean the RemoteSensing package

Dear Vikram,
It is not good to calculate NDVI from DN. The purpose of DN (digital
number) is only for packing as much information as possible into a given
âBIT-sizeâ (in Landsat 8-bit/pixel/band).
DN is practically the radiance (I think TOA?) modified with an offset
and a gain in order to
