Web7 jun. 2024 · In this study, commonly used urban indices namely normalized difference built-up index (NDBI), index-based built-up index (IBI), urban index (UI), and enhanced built-up and bareness index (EBBI) were utilized to extract impervious areas. WebUrban built-up land is a complex land-use class and has a heterogeneous characteristic in reflected electromagnetic spectrum.Therefore,it is difficult to be extracted from remote sensing imagery.This paper proposes a new index-based built-up index(IBI) by careful study of spectral features of urban built-up land.The new index distinguished from other …

Web1 jan. 2008 · The three thematic indices used in constructing the IBI are the soil adjusted vegetation index (SAVI), the modified normalized difference water index (MNDWI) and the normalized difference built-up index (NDBI). Respectively, these represent the three major urban components of vegetation, water and built-up land. Web5 jul. 2024 · 2. The study suggests that values 1 and 2 refer to built-up areas. Bai, et al. [12] modified it by excluding water areas as pre-processing steps and proposed a water eraser-normalized difference built-up index (WE-NDBI). Many multi-index-based urban indices follow the elimination approach for better ur-ban mapping, where the land surface ...
Web1 jul. 2008 · A new index derived from existing indices – an index‐based built‐up index (IBI) – is proposed for the rapid extraction of built‐up land features in satellite imagery. The IBI is distinguished from conventional indices by its first‐time use of thematic index‐derived bands to construct an index rather than by using original image bands. Web2 okt. 2012 · Remotely sensed imagery is a type of data that is compatible with the monitoring and mapping of changes in built-up and bare land within urban areas as the impacts of population growth and urbanisation increase. The application of currently available remote sensing indices, however, has some limitations with respect to …

Weba new urban index called Index-Based Built-up Index (IBI), derived from three other indices, SAVI, MNDWI, and NDBI, to map urban areas were created [6]. Also, a new index for mapping built-up and bare land called Enhanced Built-up and Bareness Index (EBBI), compared with IBI showed a high overall accuracy of EBBI in mapping built-up and bare …
