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

Two ways of 3D visualization

WebGL

Terrain Bender

Terrain data

automatically chosen from the available digital elevation/surface models

a function of the scale of the map extent/map product

Map data

current map extent (from WMS) for WebGL

downloaded original data for Terrain Bender
