A Study on Change of NDVI According to the Terrain Element

Chun-Ja Sung, Jongchul Jung

Open publisher page 1 citations

Abstract

Analysis and results of the relationship between the NDVI and terrain element such as elevation, slope, aspect in Chunahn city area are as follows. It does not show the linear relationship between NDVI and analyzed terrain element such as elevation, slope, aspect, etc. and there is a trend such that the deviation of NDVI is decreased as the elevation and slope is increased. It appears that there is trends such that the distribution range of NDVI is discontinuously changed as the elevation and slope is increased. The distribution range of NDVI is discontinuously decreased based on about 50m and 100m borderline in elevation case, and slope borderline in slope case, respectively. Any special trend is discovered in the relationship between aspect and NDVI.
