GPS Mobile Navi

This application is a position guidance system that uses GNSS (GPS) inside the smartphone. Converts from latitude / longitude to a plane rectangular coordinate system and displays the difference in m units. Since guidance is performed according to the orientation of the smartphone, it is useful in surveying fields, construction fields, and navigation for heavy equipment guidance. ・ I want to know the value of XY coordinates ・ If it is latitude and longitude, the amount of difference cannot be known. ・ I want to perform a reverse survey ・ I want to find a reference point This is useful in situations where you need to convert latitude / longitude-> XY coordinates in real time. UTM is used as the calculation method for coordinate transformation. * When used in Japan, it is compatible with the World Geodetic System (WGS84) / Japan Geodetic System.
