Positioning of measuring stations with the use of Global Positioning System (GPS)
The majority of the NDBHMI stations were georeferenced
using a Global Positioning System (GPS). A group
of experts visited about 1500 stations belonging to the Participating
services, in order to confirm the coordinates of their positions. The
data were cross referenced, regarding their quality and reliability, with
the available information for the stations and the administrative information
that have a geographical dimension, were checked using spatial operands,
before they were imported into the main geodatabase of geographical and
descriptive information.
