I have seen many articles here at CodeProject about coordinates and GPS signal handling, like "Writing your own GPS Applications" and "Distance between locations using latitude and longitude" among others. Most of them do some tasks around a latitude/longitude pair, but them don t handle coordinate storage with care. This article provides a solution to manage coordinates at both memory and persistent storage (XML or database), complying with ISO 6709 standard (Annex H - Text string representation), in concordance with World Wide Web Consortium s LatitudeLongitudeAltitude workgroup. C#语言中封装了ISO 6709坐标系统(I have seen many articles here at CodeProject about coordinates and GPS signal handling, like Writing your own GPS Applications and Distance between locations using latitude and longitude among others.
