iGeoTrans – a novel iOS application for GPS positioning in geosciences.

The iGeoTrans is an iOS application designed for navigation purposes for iPhone, iPad and iPod Touch. This application uses Global Positioning System (GPS), Assisted GPS system, GLONASS, Wi-Fi and Cellular Network for positioning. The iGeoTrans has included datum transformations and map projections that enable users to convert the collected data between different coordinate systems for almost all areas in the world. In addition, other features are also included such as distance, area measurements, and GPS results could be exported to the AutoCad dxf format for GIS softwares. The average horizontal and vertical root mean square errors (RMSEs) for the static test are around 4.11 and 3.51 m, respectively. The horizontal RMSE for the dynamic outdoor test is around 2.72 m. The iGeoTrans application can be used to support surveying, mapping and geosciences fieldworks for any area in the world. [ABSTRACT FROM PUBLISHER]
