- Title
- FMN Spiral 3.0 Geospatial Data Exchange Service Profile
- Description
- Geospatial data are being produced by different organisations and need to be exchanged between different participants using standardized exchange formats. These datasets would then be loaded into specialised geospatial information systems (GIS) and published via standardized Web Services (e.g. WMS or WMTS for raster data/maps).

Guidance
The direct exchange of data (via automated or manual file transfer) is to be considered only in case of limited connectivity (no regular access to the network).
Often the exchange of large geospatial (raster) data sets between Geo organizations of different Mission Participants is conducted in proprietary formats such as
- Shapefile (ESRI), technical description athttps //www.esri.com/library/whitepapers/pdfs/shapefile.pdf
Or proprietary compression image formats such as
- Multi-resolution seamless image database format (MrSID Generation 3), technical description athttps //www.loc.gov/preservation/digital/formats/fdd/fdd000184.shtml. Data in MrSID format could be transformed to GeoTIFF. The JPEG 2000 image compression standard offers many of the same advantages as MrSID, plus the added benefits of being an international standard (ISO/IEC 15444).
- Erdas Compression Wavelet (ECW) which is optimized for aerial and satellite imagery.
