Data Processing
Plaani joonestamiseks kasutati AutoCAD-i ja PDS2000 tarkvara. Lamberti koonilise konformse projektsiooni ristkoordinaatidest arvutati geodeetilised koordinaadid WGS-84 projektsioonis programmiga TRANSDAT Ver 12.04 (Licensed for „Peeter Ude, Tallinn“, koostanud C.Killet Software Ing-GbR).
