Hi,
I need some help about the IDL interpolation or gridding function.
I have two data sets, both data sets are longitude x latitude wise in
this one is regular and another is irregular wise. I will give example
then you will get clear idea about my problem.
Data1: irregular data1 set
longitude1=[10.5,21.4,0.51,170.45,.......]= 600 points
latitude1=[12.5,0.2,12.2,-10.2,-5.5,.......]= 600 points
date1 =[21.32.12.45.13.45.2.34.1.23.]= 600 points
Data2: regular grid model data sets (97 x 48)
longitude2=[0.0,3.75,7.5,11.25......] = 97
latitude2= [-87.15,-83.47,-79.77...] = 48
data2= [97 x 48]
I want to interpolate/grid the model(Data2) values to the nearest
longitude1 x latitude1 (data1) sets.
How to interpolate the model (data2) values to the data1 values.
I am awaiting for your reply,
Thanking you,
Kishore
