GeomatikaDroid: An Android application for improving theodolite measurement

Abstract

In the era of the fourth industrial revolution, the implementation and integration of digital technology and physical processes are unavoidable in which teaching and learning geomatic are included. In the field, students generally make mistakes in calculation of horizontal distance and height difference that are caused by the error in staff reading or/and its recording. The general aim of this research is to develop geomatic application on android, so that it will be portable and easy to use in order to reduce the parallax and staff reading error in theodolite. In the design and development of GeomaticDroid Application, the Java and PHP programming languages were implemented and data were recorded in MySQL. Application testing and debugging were conducted using Android 7.0. In the field testing, GeomatikaDroid has shown consistencies in clarity, better legibility of staff reading and recording compared to conventional staff reading and recording method. GeomatikaDroid has maximum parallax error of 1 mm. Meanwhile, the measurement without GeomatikaDroid makes staff reading error of 18 mm. The z test of two independent samples proved that those two samples have significant differences in error.
