These applications require the existence of structured geoinformation containing the right geometric data and credible attributes on the road network status.

GEOMATICS has realized a significant investment towards that direction, developing the Greek Road Network Data Base - HellasROADNET- that constitutes the most complete registration and documentation of the Greek road network in GIS environment.

HellasROADNET builds up to technical specifications corresponding to a 1:50.000 scale and contains the following layers of information and attributes.

• Road network classified in several categories.
  
• Motorways
  
• First, Second and Third class National Road Network
  
• First and Second class Regional Road Network
  
• Communal network
  
• Tracks
  
• Forest roads
  
• Legislated routes according to Ministry of Public Works legislation scheme.
  
• Road numbering, according to National - International and European coding scheme
  
• Exits - Entrances of motorways
  
• Arcs / Nodes coding for routing applications.
