Hello IDL users
I am new to learning IDL, I have looked at all the Web Seminars, even
order books Gumley, Bowman, & Fanning and have been reading them . I
am just having trouble with the basic. I am trying to set my directory
for where my data is located. I tried running a simple program to read
a binary file but can not get it to work. Can anyone please give me
some advice on how to solve this problem.
A set of NDVI (Normalized Difference Vegetation Index) data with
global coverage and
1oX1o degree resolution is given in Binary format (file name:
EOS754_HW1_Data_NDVI.zip).
Please read the data in your environment or by a program, and display
the following results.
a. Color images of NDVI values for July 1982 over the US continent
(17oN-51oN and
130oW-62oW).
b. Display the time series of NDVI values over the pixel centered at
(38.5oN, 77.5oW) for
July 1981-June 1983 period.
I am understanding the syntax but something is not click with me. Any
help that anyone can provide would be greatly appreciated

Whether or not this is a homework question, you'll find that help is more likely to be given if you show what you have
already tried to do that didn't work.
