Abstract

The purpose of research were (1) a conceptual, functional model designed and implementation for railway geometric design, (2) standard operational procedure made for railway geometric design using satellite imagery and digital terrain model, (3) calculated geometric information on the railway route so that fulfilling geometric national and international standard, (4) horizontal alignment drawing presented on the railway route, (5) vertical alignment drawing presented on the railway route. Descriptive method is used for the research. South Sumatra Province, Indonesia was study location. The research was conducted on July 2016 to January 2017. A spatial analysis is used to calculate horizontal and vertical geometric information. Horizontal and vertical geometric calculated on railway route based on satellite image and digital terrain model could be faster, easier and cheaper than terrestrial and analog method.
