OS MasterMap and GO Loader

GO Loader is the most effective solution for modelling, loading and maintaining OS MasterMap® in an Oracle (Spatial or Locator) database.

GO Loader was designed by Snowflake Software in response to the need to provide a tool that was reliable and flexible enough to handle OS MasterMap data. Learn more about Snowflake Software's unique insight into OS MasterMap on the OS website.

GO Loader is the ideal choice for OS MasterMap users as it supports all layers (including ITN) and includes specific support for change-only updates, duplicate removal and feature archiving.

 

"GO Loader is a very powerful and flexible tool that does just what we need. It enabled CCW to move its OS MasterMap project ahead quickly and with relative ease."

A number of features have been developed specifically to support OS MasterMap:

  • Choose from a number of predefined data models and start loading your OS MasterMap holding within minutes of using GO Loader
  • Remove duplicate features supplied in multiple OS MasterMap chunks
  • Apply OS MasterMap change-only update files to remove the need to reload data
  • Create archives of deleted and changed features when applying updates
  • Save disk space by reading OS MasterMap files in their compressed form
  • High speed and parallel loading can save valuable time when loading hundreds of millions of features (see our OS MasterMap National Load statistics for GO Loader v1.5)
  • Validate your holding using the Feature Validation Data Set (FVDS)
  • Translate and model complex attributes into a choice of relational structures and tables
  • Supports all layers of OS MasterMap data including Address, Address Layer 2, ITN RRI and Imagery Metadata.
