Novel Functionalities  Customizable Map Content  3D on Demand  Customizable Visualization Symbolization by means of SLD  Symbolization of SVG point and raster data   Time navigation C. Iosifescu, I. Iosifescu & L. Hurni | 20.09.2013 | 7

Geoportals powered by GeoVITe  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 C. Iosifescu, I. Iosifescu & L. Hurni | 20.09.2013 | 8

Customizable Map Content  Add layers from different map categories  Adjust transparency and modify layer order Facilitates map comparison C. Iosifescu, I. Iosifescu & L. Hurni | 20.09.2013 | 9

Map comparison in GeoHistory C. Iosifescu, I. Iosifescu & L. Hurni | 20.09.2013 | 10

3D on Demand  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  C. Iosifescu, I. Iosifescu & L. Hurni | 20.09.2013 | 11
