SNIG is the Portuguese Spatial Data Infrastructure and Directorate-
General for the Territory (DGT) is responsible for its operational
coordination. In 2015 DGT began a strategic and technological
restructuring process of this Spatial Data Infrastructure (SDI) and
in 2019 DGT launched the new SNIG GeoPortal and formalized
the National Register for Geographic Data (RNDG). This new infrastructure
is built on Open Source technology and, in addition
to enhancing the platform design to make the interface more
dynamic and user-friendly, new functionalities have also been developed
to improve spatial data sets searching and visualization
processes. This paper reflects on the developments of the new
SNIG GeoPortal and the implementation of the RNDG.
