Comparing the results from two different datasets

I am comparing the results obtained from two different datasets- However Data1 is of the size of 119*177 size corresponding to the lat1/long1 file

Data2 is of the size 361*361 and is associated with a different lat/long file. I want to have them in a common lat/long frame. which MATLAB function i can use??

Any suggestions/help is appreciated.

You can do interpolation and get the dimensions of data sets to same size. doc interp2.

I did that already, but i am more concerned about having the same coordinate system

[KSSV]

lat and lon for both the data sets are different?

[Sophia]

Yes, lat/lon files for both dataset are different. And i am trying to find out the way that i can use a common lat/lon file and can see the difference in the results obtained from both datasets.

[KSSV]

If they are different how you expect them to get to same coordinates? Is one dataset sub set to other? Any intersection? Or they are completely exclusive?

[Sophia]

One is subset of the other

[KSSV]

Then what is the problem? It is easy. Use same resolution for both the data sets and do interpolation.

[Sophia]

any suggestions- how to do that?

[KSSV]

Get the resolution of both the grids. Choose the minimum one, get the other grid to this resolution and do interpolation.
