text: **3.3 Visualization of Geo-Spatial Data (map.apps)**
  
  The visualization of geo-spatial data within the European Data Portal provides previewing 
  functionality for spatial open data. The aim is to allow the user to assess if a dataset meets specific 
  requirements in terms of spatial and thematic coverage. The functionality that is provided in the 
  header (links to disclaimers and language switching) is consistent in the entire portal. 
  
  **3.3.1 How to visualize geo-spatial data from a dataset resource**
  
  Accessing the geo-spatial visualization is achieved via the Data Platform interface. A user searches for 
  specific data, enters the dataset view of reasonable results and displays the available distributions 
  (see Section 3.2.5). If a dataset distribution is supported by the geo-spatial visualization, a globe 
  button is displayed (see Figure 3). This is the entry point into the map viewer application. Supported 
  formats are OGC Web Map Service (WMS) and GeoJSON. If the user visits the geo-spatial 
  visualization for the first time, an interactive user tutorial is provided to guide the use through 
  specific functions of the user interface, similar to this written user manual.
