Hi All,

I have been reading a lot and for a long time HDF documentation and
samples (when ever possible), but I guess, till the time I don't wet
my toes, I will not gain eve the basic experience :).

I am on LinuxMint 64 bit OS, with Python and HDF libraries already
installed. I need help / support in coding using python and c++, both,
separately in cli mode.

Background : This data is of a road alignment centre line (File1,
irregular interval), the next data is of Grade file (irregular
interval, File2).

Objective : File1 - File2 = TempFile1

TempFile1 :
containing all Km's in meters {intermediate and regular interval} and
their respective Heights,

Plotting graphically TempFile, by over laying on data of File 1 & 2.

Q) Will my work directory be "/" directory ?

Q) and where or how, do I create File1, File2 and TempFile ?

Q) What parameters do I need to set, to insert/write data into each
file ? and then read from it ?

Q) How do I edit data in the file directly ? Add remove columns in
each file, respectively ?

I do understand, calculation will be done at the code (python or c++) level.

I have sample data, please do let me know when to post it.

Thank you

Nitin Chandra
