Hello to everyone,
I am new here and I am new at all.
I have a set of data in txt file. For example something like this:
x y z
30 50 5
32 48 6
28 45 10
22 49 8
The points are scattered because are collected from some weather stations in different places. x is longitude and y latitude and z temperature.
1.I would like to know if there is any way to read the data from this txt file and to plot contours using an interpolation method (for example IDW).
2.At the same time I would like to plot the corresponding coastline on the background.
Thanks on account,
please for more clarifications just ask me.
