Abstract
Today, millions of mobile applications (apps) have been created and placed in Apple Store and Google Play Store. Users can easily download from the app stores and operate them using their handy gadgets. By merging information and communication technology (ICT) with geomatics, we are able to leverage smartphones and tablets for data acquisition and sensing, data processing and computation as well as distribution of geospatial information. Many sophisticated survey programs and tedious computations can be leveraged by using automated service-oriented programs, either in web-based apps or mobile apps. This study has created mCOORD mobile app for coordinate system conversion in Malaysia. The developed mobile app works in two ways: firstly, it transforms a pair of defined coordinates into their relevant coordinate reference systems; and secondly, it allows immediate viewing of the location in an interactive map. As for this study, we presented the performance and efficiency of the app by comparing the converted data with authorized GDTS conversion tools and several open-source GIS software. For instance, the differences of converted coordinates obtained from mCOORD and GDTS are relatively small and within the allowable tolerance. Hence, the successful development of this publicly accessible coordinate conversion app is beneficial to all GIS users in Malaysia.
