Title: | A new technique for seasonal land-cover change analysis using directional brightness differencing | Contributor(s): | Sinha, Priyakant (author); Kumar, Lalit (author) | Publication Date: | 2012 | Open Access: | Yes | Handle Link: | https://hdl.handle.net/1959.11/10759 | Open Access Link: | http://dl6.globalstf.org/index.php/jet/article/view/728 | Abstract: | Due to seasonal spectral variability in land-cover of cool temperate climatic conditions, the method that suits best for seasonal land-cover change identification remains uncertain. The study tested 11 different binary change detection methods and compared their capability in detecting land-cover change/no-change information in different seasons. Multi-date Thematic Mapper (TM) data pertaining to different seasons were used for a wide set of change image generation. A relatively new approach was applied for optimal threshold value determination for separation of change/no-change areas. Research indicated that irrespective of the method used, the results using vegetation index change images, particularly Normalized Difference Vegetation Index (NDVI)-based change images outperformed all other tested techniques in change detection process (overall accuracy> 90% and Kappa value> 0.85 for all six change periods). | Publication Type: | Journal Article | Source of Publication: | The GSTF Journal of Engineering Technology, 1(1), p. 61-66 | Publisher: | Global Science and Technology Forum (GSTF) | Place of Publication: | Singapore | ISSN: | 2251-371X 2251-3701 |
