plotting map from a matrix

I have a matrix with the first row as longitude values, the first column as latitute values and the rest of the values are soil moisture values corresponding to each lat and long for INDIA. Basically it is raster data. How do i produce a map showing the geospatial variation of the soil moisture values?

You can use pcolor. Read about it. Also have a look on surf. You can have a look on this package:
