Frequently asked questions

On these pages you can find answers to frequently asked questions. The answers are grouped into two thematic units:
 

• NSDI generally – covers general answers about NSDI and NSDI inclusion
• Spatial data, models and formats – covers more specific answers about spatial data themselves that are part of the NSDI

As the frequently asked questions will be regularly updated in accordance with the interest of the NSDI subjects, please follow the new announcements on our website.
