You can calculate land changes using time series datasets for long period of time.
It is the best way to observe changes happened during the selected period.
we use data or map of land use and cover change extracted from satellite image to introduce it in hydrological, hydrogeological, agricultural or climate model. and this to estimate flow, erosion, evapotranspiration, groundwater recharge......
To understand where land is changing, how it is changing and why it is changing. And then plan for sustainable land use.
Using remote sensing technique one can gather the regional information on land use / land cover changes within shorter duration, very limited man power and cost. One more important feature of application of remote sensing technique is to get not only the data on spatial variations but also on the temporal variations. The purpose and usefulness of this information differs with the field of application like hydrology; forestry; agriculture; urban development; etc.
