SNIG es la Infraestructura Portuguesa de Datos Espaciales y
la Dirección General del Territorio (DGT) es responsable de su
coordinación operativa. En 2015 la DGT inició un proceso de
reestructuración estratégica y tecnológica de esta Infraestructura
de Datos Espaciales (IDE) y en 2019 la DGT lanzó el nuevo
GeoPortal SNIG y formalizó el Registro Nacional de Datos
Geográficos (RNDG). Esta nueva infraestructura se basa en la
tecnología Open Source y, además de mejorar el diseño de la
plataforma para hacer la interfaz más dinámica y fácil de usar,
también se han desarrollado nuevas funcionalidades para mejorar
la búsqueda de conjuntos de datos espaciales y procesos
de visualización. Este documento reflexiona sobre la evolución
del nuevo GeoPortal SNIG y la implementación del RNDG.
