GML Viewer

Snowflake Software's free to download GML Viewer is a new product created using the core framework of our OS MasterMap Viewer and a subset of the generic parsing technology used in our flagship product GO Loader. With over 30,000 downloads, the viewer has been extremely popular for users wishing to view Ordnance Survey's GML2 flagship product.

Since its launch in 2001, however, there are now many different GML application schema available throughout the world.
