As one of the original creators of GML, Galdos Systems has significant expertise in creating schemas in the Geography Markup Language. GML application schemas provide an essential ingredient in geospatial data sharing by specifying a common language for filters, queryies, and responses.
Sometimes, a complete GML schema is not necessary to describe the data for a domain. A GML Profile is an expression of a subset of a GMLschema that is used within a specific application domain. At other times, a GML schema may be made up of a number of sub-schemas, each of which describes a specific part of the dataset.
