Files in whatever format can be uploaded: doc, pdf, images, GIS layers, etc. For the latter the distribution in a compressed (ZIP) file is recommended. You can include the GIS data, the legend, documentation that can help the interpretation of the data, related reports, detailed descriptions of the data processing, base data used to create the dataset specified and/or other relevant information.

Tips:
- Make sure the total size of the compressed file is reasonable (less than 50 MB).
- You can create several smaller files when appropriate and upload them sequentially.
- You add the size of the file at the end of the description field.
