How do you check for land cover change?

How do you check for land cover change?

The most commonly used land change detection methods include image overlay, classification comparisons of land cover statistics, change vector analysis, principal component analysis, image rationing and the differencing of normalized difference vegetation index (NDVI) (Han et al., 2009. (2009).

Which sensors are useful for land use land cover studies?

Remote-sensing has been widely used in updating land use/cover maps and land use/cover mapping has become one of the most important applications of remote sensing (Lo and Choi, 2004). Landsat-TM images represent valuable and continuous records of the earth’s surface during the last 3 decades (USGS, 2014).

What is meant by land use change?

Land use change is a process by which human activities transform the natural landscape, referring to how land has been used, usually emphasizing the functional role of land for economic activities.

What is land use land cover change?

Land use and land cover change (LULCC) is the conversion of different land use types and is the result of complex interactions between humans and the physical environment[9]. LULCC is a major driver of global change and has a significant impact on ecosystem processes, biological cycles and biodiversity[7, 10, 11].
