How can I create Nigeria map and fill the my data on it?

I have an excel file with 13 columns as shown in the attached sampledata. The file contains 40 station names and their longitudes and latitudes in the first three columns respectively while the other 11 columns contains the resulting data. I want to create Nigeria maps with geographical coordinates (4 degree North by 14 degree North, 4 degree East by 14 degree East). Then, I want fill each of the 11 data on the Nigeria map and extrapolate them fill the map to the edges using krigging or any available methods. Can somebody help me out please. Thanks.

[A,b] = xlsread('sampledata.xlsx')
