  12. CONCLUSSIONS – In view of the problems had in the Spanish repeat station network because of changes in the civil conditions, mainly due to the growing of towns and villages, its been decided to locate them at reserve zones. The time spent looking for these places in the last years has made impossible to do the complete survey in these two years, as normally is done.

  13. CONCLUSSIONS • The variometric method has proved to be more precise than the classical one, not only in the variometric stations but also for repeat stations at a distance of 150-200 kilometres
