Urban sprawl measurement from remote sensing data

Conceptual ambiguity of sprawl and lack of consensus among researchers have made the measurement of urban sprawl very difficult, especially from remote sensing data. There are many scales and parameters that are in use to quantify the sprawl; however, many of them are suffered from several limitations. The objective of this article is to document and discuss these sprawl measurement techniques along with their merits and demerits towards the absolute acceptance or rejection. The paper also highlights the scope and direction of future research for the measurement of urban sprawl.
