# GeoPortal Data Viewer App

The "Geoportal data-viewer" technology allows users to access and search for spatio-temporal documents through a web GIS which allows them to: (i) navigate and select the projects published in the system by "geographical map" (spatial dimension) , (ii) navigate and select the relationships between projects (evolution of over time) via "timeline" (temporal dimension), (iii) view metadata and resources (images, layers, etc. .) of documents via the "project view detail", (iv) export a view of the map with the layer of interest or add the layers of a project to the main map, (v) manage the order and overlapping of the layers, (vi) execute spatial queries on the layers and view the results, (vii) search through metadata or temporal dimension queries for the projects of interest, (vii) apply spatial filters for cross-layer.
