“…ones) provide more detailed information about the general shape of the landscape rather than the TPI values from just a single neighborhood. Therefore, the combination of TPI grids generated at different scales results in the identification of complex landforms [13]. Since elevation tends to be spatially auto correlated, the range of TPI values increases with scale.…”

This paper aims to classify and analyze landforms in the broader area of Messaria region of Ikaria Island, Greece using GIS techniques. Landform categories were determined by implementing Topographic Position Index (TPI). The classes obtained from the TPI were related with the geological pattern of the study area for further interpretation of the landform evolution. The analysis of the data indicates the presence of three landform units in the study area, affected mainly by geology.

“…Over the last decade, Digital Elevation Models have been widely used to automatically classify landforms [3], [4], [5], [9], [11], [13]. Either by computing differential geometry algorithms or by defining spatial patterns, both approaches focus on the following: to reduce time consumption and generalize local findings.…”

“…Such a feature may be reasonably classified as an upland drainage. Conversely, a point with a positive small-neighborhood TPI value and a negative large-neighborhood TPI value likely represents a small hill or ridge in a larger valley [13] (Table 1 and …”

This study is aimed at investigating the relationship between landform classification and vegetation in the southwest of Fars province, Iran. First, topographic position index (TPI) is used to perform landform classification using a Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM) with resolution of 30 m. The classification has ten classes; high ridges, midslope ridges, upland drainage, upper slopes, open slopes, plains, valleys, local ridges, midslope drainage and streams. Visual interpretation indicates that for the local, midslope and high ridge landforms, normalized difference vegetation index (NDVI) values and tree heights are higher as compared to the other landforms. In addition, it is found that there are positive and significant correlations between NDVI and tree height (r = 0.923), and landform and NDVI (r = 0.640). This shows that landform classification and NDVI can be used to predict tree height in the area. High correlation of determination (R 2 ) 0.909 is obtained for the prediction of tree height using landform classification and NDVI.
