Description:
The Austrian geoid is computed by the fast collocation method. As for the Austrian territory, the input data consist of a 50 x 50 m digital terrain model, about 30.000 gravity data, about 700 deflections of the vertical, and GPS derived points. As for the neighboring countries, gravity and height information is available in different quality and density. The provided output is the geoid and quasi geoid undulation (in meters) from north to south and for each latitude from west to east.

A header file is also provided with the following information (unit degree):
southern latitude northern latitude
western longitude eastern longitude
latitude increment longitude increment

In particular:
Western part
46 ° 38.25' < lat. < 47 ° 47.25'; 09 ° 31.25' < lon. < 12 ° 41.25'
dlat. = 0.05; dlon. = 0.083333
Eastern part
46 ° 20.25' < lat. < 49 ° 02.25'; 12 ° 41.25' < lon. < 17 ° 11.25'
dlat. = 0.05; dlon. = 0.083333
