Copan for Windows is a very efficient and easy-to-use geomatics engineering tool for computing and managing plane survey coordinates. It does numerous COGO calculations, processes and adjusts field survey data, computes and adjusts map traverse data, performs map checks, calculates areas and perimeters, performs coordinate transformations, and imports/exports Ascii files.
It supports quadrant bearings as well as azimuths, and gons (grads) as well as degrees. It supports Geodimeter and Leica total station formats and will soon be expanded to support others. Its coordinate files may be copied to a memory card and used directly by the Palm and Pocket PC versions of Copan.
Designed for land surveyors, geomatics engineers, professionals and students, Copan for Windows is available for download, free of charge.
