Verification of Certificates of Origin in Chile

Origin procedures concern both the issuance and verification of certificates of origin. Certification of origin consists of demonstrating that a product complies with standards of origin that qualify a good for access to the corresponding tariff preferences in a destination market, and that no triangulation has occurred in this process. Verification of origin means not only formally checking the validity of the certificate of origin, but also ensuring that the merchandise covered by the certificate genuinely qualifies as originating. All trade agreements carry rules on origin procedures, which continue to apply after the corresponding tariff reduction programmes have concluded.  This edition of the bulletin examines the case of Chile, because of the large number of trade agreements the country has signed.

Influence of distance, geometry and number of control stations on quality of local geodetic networks for the purpose of georeferencing of rural properties

The implementation of local geodetic networks for georeferencing of rural properties has become a requirement after publication of the Georeferencing Technical Standard by INCRA. According to this standard, the maximum distance of baselines to GNSS L1 receivers is of 20 km. Besides the length of the baseline, the geometry and the number of geodetic control stations are other factors to be considered in the implementation of geodetic networks. Thus, this research aimed to examine the influence of baseline lengths higher than the regulated limit of 20 km, the geometry and the number of control stations on quality of local geodetic networks for georeferencing, and also to demonstrate the importance of using specific tests to evaluate the solution of ambiguities and on the quality of the adjustment. The results indicated that the increasing number of control stations has improved the quality of the network, the geometry has not influenced on the quality and the baseline length has influenced on the quality; however, lengths higher than 20 km has not interrupted the implementation, with GPS L1 receiver, of the local geodetic network for the purpose of georeferencing. Also, the use of different statistical tests, both for the evaluation of the resolution of ambiguities and for the adjustment, have enabled greater clearness in analyzing the results, which allow that unsuitable observations may be eliminated.
