Quantitative Morphometric 3D Terrain Analysis of Japan Using Scripts of GMT and R

In this paper, we describe two related scripting methods of cartographic data processing and visualization that provide 2D 3D mapping Japan with different algorithm complexity. The first utilizes Generic Mapping Toolset (GMT), which is known as an advanced console-based program for spatial processing. modules GMT combine the functionality aspects geoinformatics, especially effective rapid analysis large geospatial datasets, multi-format processing, in modes. second presents use R programming language analysis. This method packages ‘tmap’, ‘raster’, ‘maps’, ‘mapdata’ to model morphometric elements Japanese archipelago, such slope, aspect, hillshade elevation. general purpose graphical package ‘ggplot2’ was used prefectures Japan. approaches demonstrated established correspondence between languages cartography determined scripts They outperform several well-known state-of-the-art GIS due their high automation Cartography has largely reflected recent advances science, development languages, transfer extends shift from traditional languages. As a response these new challenges, paper advantages using mapping, consist repeatability flexible applicability similar works.
