Βιβλιοθήκη γεωδαιτικών μετατροπών συντεταγμενων Μετατροπές φ, λ <-> X,Y ΕΓΣΑ87 (GR87), WGS84, κλπ. Έκδοση 0.4.0 - 3 Οκτωβρίου 2006 Την βιβλιοθήκη αυτή την ανέπτυξα με ιδίους πόρους στον ελεύθερό μου χρόνο για να χρησιμοποιηθεί σε ένα ερευνητικό πρόγραμμα της ΙΤΙΑς, ωστόσο πιστεύω πως είναι γενικότερα χρήσιμη και έτσι την βάζω εδώ για να την κατεβάσει όποιος θέλει. Επιπλέον δίνω τον κώδικα της βιβλιοθήκης, ώστε όποιος θέλει να την βελτιώσει, χρησιμοποιήσει σε άλλα προγράμματα κλπ. Αν και θα ασχοληθώ με την συντήρηση και βελτίωση του κώδικα, θα ήταν πολύ ευχάριστο αν κάποιος που έχει εντοπίσει τυχόν λάθη ή έχει κάνει βελτιώσεις, συντάσσει Makefiles και installation scripts, κλπ μου τις έστελνε για τις εντάξω. Επιπλέον η σελίδα αυτή πρέπει να μεταφραστεί στα αγγλικά (ζητούνται εθελοντές!). Η βιβλιοθήκη σε μορφή DLL itranscoords.dll (έκδοση 0.4.0) Κατεβάστε οπωσδήποτε το παραπάνω DLL αν θέλετε να χρησιμοποιήσετε κάποιο από τα προγράμματα ή Excel που δίνω στην συνέχεια. Αυτόνομο πρόγραμμα μετατροπής συντεταγμένων Excel gr87transformsHatt.xls
