#### This scripts collects a bunch of helpful proj transformation strings and shows their
#### usage for coordinate systems that are mainly used in germany and their resprective federal states.
#### The script focuses on open source projects gdal / ogr and proj.
#### INFO:
## Die Transformation erfolgt immer nach dem Prinzip:
## (YRe, XHo)GK → (Br1, Ln1) Ellipsoid(GK) <-> (Br2, Ln2) Ellipsoid(ETRS89) → (YEa, XNo)UTM
## Damit werden zunächst alle projizierten Hoch- und Rechtswerte aus dem Gauß-Krüger-System in Lat/Long-Werte im Gauß-Krüger-System (geographisch) transformiert.
## Anschließend werden die geographischen Koordinaten mit GK-Bezugssystem in das UTM-Bezugssystem überführt (es blieben jedoch Lat/Long Werte).
## Im letzten Schritt werden die geopraphischen Koordinaten der UTM-"Kugel" in projizierte UTM-Easting und Northing Koordinaten umgewandelt.
#### Gute Zusammenfassung der NTV2-Transformations-Verfahren in Deutschland
