Novel Functionalities

||

OSPER/SwissExperiment

Objective: to provide a platform for large scale sensor network deployment and information retrieval and exploitation

GeoIDEA.ro

Objective: to implement a geoportal allowing the access to geodata in Romania in a usable format and under an open license

GeoHistory

Objective: to facilitate the comparison between historical maps (17th-20th cent.) with modern raster and vector data, therefore making possible to observe and study the changes which took place in the area Canton of Zurich over time


Geoportals powered by GeoVITe
