Landsat ETM+ Gap filling & WELD data
Hey Thank you for the heads up! WELD data is available here: http://weld.cr.usgs.gov/ Data extraction cannot be done here since need a longer time series. All I want is to extract values from the LS images at a certain number of months. All the best! Nuno

Re. your second q, please provide links to or instructions for obtaining one of these files and someone could have a go. Generally I would recommend *not* warping to UTM, or any other projection, unless you really need to since much of the data extraction and merging can be done without such a destructive process. You haven't provided any ideas about what you are trying to do though. Converting code is about as hard as the original code is to understand, so I would highly recommend that you try to do that first so you can break down the the tasks and address them individually. It's too much to ask a general question about doing that, and there is a lot you could do first. Cheers, Mike. On Thu, Oct 16, 2014 at 2:29 AM, Nuno S? <nunocesardesa at gmail.com> wrote:
Hello Eric Thank you, I had seen it though. Are you aware if the rgdal able to reproject it into UTM? All the best, Nuno On 15 October 2014 15:52, ejc <eric.j.christeson at gmail.com> wrote:
For the WELD data question. According to: http://globalmonitoring.sdstate.edu/projects/weld/
Section
"Version 1.5 Product Documentation", subsection "Product Map
Projections",
they use an Albers Equal Area projection. Thanks, Eric On Wed, Oct 15, 2014 at 5:16 AM, Nuno S? <nunocesardesa at gmail.com>

Hey So, the first question is - is there an implementation of the newer algorithms for Gap filling in any R package? If not, I would be available to work with an expert to try to develop
it
here - some of the actual IDL code is available through Dr. Xiaolin
Zhu's
page: http://geography.osu.edu/grads/xzhu/ , so would it be so costly
to
do
it here?
The second is WELD data, I am absolutely confused on what is the
projection
they use on that dataset.. can anybody enlighten me?
All the best!
Nuno
