[00:00:01.240]We will look at this problem now from the computational approach.
[00:00:05.720]Our goal is to somehow divide this problem into smaller tasks that can then
[00:00:12.690]be solved using a programming language or an environment such as R So let's look at
[00:00:20.394]the problem in a very simplified form.
[00:00:24.920]We are given data from the instrument in the field and the data has rows which are
[00:00:33.870]defined by columns.
[00:00:35.920]So the first column in this case is the wavelength that the instrument has
[00:00:41.748]measured and then second column that we see is the measure of that wavelength
[00:00:47.809]from the instrument in plot number one.
[00:00:51.400]The third column in this case is measure of the wavelength from the instrument in
[00:00:58.999]plot #22 and so on.
[00:01:01.280]We also have the yield that has been observed from the same plot.
[00:01:08.480]The columns that are of interest to us are the adjusted yield and the dry plot.
[00:01:13.920]The dry plot column shows that plot #1 had the adjusted yield for 0.964023535,
[00:01:21.906]which corresponds to the plot number one in the instrument column.
[00:01:29.000]Same way we have the yield for plot #22 and we also have the data for plot #22.
[00:01:35.600]Similarly for 20, 23, 44, 45, 66 and 67.
[00:01:41.160]The water index is given by R of 900 by R of 970.
[00:01:46.880]So having that in mind, the first step that we want to do is we
[00:01:52.546]want to find out the wavelength that is closest to 900 and 970 in case of water
[00:01:59.628]index.
[00:02:00.520]Then we want to average 2, four or six bands on both sides of that
[00:02:05.742]wavelength.
[00:02:07.760]Next, we will like to transpose the data into a
[00:02:11.880]new table where the rows become the column and the column becomes the row.
[00:02:18.680]We will then add the columns with water index ratio and then we will join the
[00:02:24.296]yield table based upon the common plot number.
[00:02:27.800]And finally we will calculate the coefficient of correlation.
