Dear Parakhi mitra,, My research is in landscape modelling and the work will use geostatistical methods, GIS and 3-D spatial modelling softwares for reconstruction and scientific visualization of soil-landscapes.Tho i prepared my research interest and sent to the profs,, i am really unaware of landscape modelling. To be honest,, I don know even a single model to describe a landscape,, but for sure its not like just jumping into water also,, my research interest happened to hit a major problem of central and northern florida And going into detail what my degree would be like was out of question,, as i was replied till the last hour that the assistanship was very competitive and many students competiting for it. Gettign back to homeland would be a tuft deal at this time. I think my course could more specifically called Land Information Systems,, coz i find GIS a very broader duscipline take care
