Open Standards

Open standards are critical in many domains to support interoperability and efficient data sharing. Without open standards, data sharing can be a challenge, complicated by different data models and document formats. In some areas, such as emergency response, the inability to easily share information can slow relief efforts, and complicate coordination between agencies, with potentially devastating results.

Galdos has extensive experience with Geography Markup Language (GML), and has been instrumental in creating and periodically updating the standard. GML, an XML grammar designed to express geographical features, is an Open Geospatial Consortium (OGC) specification and an ISO standard.

Galdos Systems wrote The Book on GML; Geography Mark-Up Language: Foundation for the Geo-Web is a must read for anyone working with GML data, and includes illustrations and worked examples.

Galdos has also done work in the rapidly-expanding field of CityGML, working on projects that leverage the data to manage urban development, as well as building products and tools that view and manage CityGML data.

Galdos has executed projects that leverage standards for aviation information (AIXM, SWIM, and WXXM) and emergency response (NIEM – the National Information Exchange Model), and in the geotechnical field, working with the Data Interchange for Geotechnical and GeoEnvironmental Specialists (DIGGS).

Standards Development

Galdos Systems has been involved with the development of a number of open standards, working with the submitting organization to standardize data structures and code lists, and assisting with the process of getting the result published as a standard. One project that Galdos undertook in this area was to work with Google to get the first version of the KML encoding for data displayed on Google Earth accepted as an OGC standard. Galdos also has an extensive offering of courses on various open standards.

Galdos was part of the team that submitted the KML 2.2 Specification to the OGC, which was approved as an open standard in 2008. Galdos continues to be active in ongoing development of the KML standard through the OGC Mass Market Domain Working Group. This group approves specific OGC KML Extensions developed by other KML Working Groups. Anyone can create an extension for KML but, in order for an extension to approved as part of the KML standard, it must follow the OGC’s defined process and be approved by the Working Group responsible for maintaining that standard.

Supporting Open Standards

Galdos supports open standards and initiatives, and is active on a number of technical committees and working groups within various standards bodies. Galdos has been instrumental in the development of a number of standards in the Open Geospatial Consortium (OGC) and the International Organization for Standardization (ISO), and has provided input to a number of the standards bodies that are influential in the creation and ratification of standards that affect GeoWeb services.

The formal international standardization of these specifications is very important to Galdos and its customers. Galdos participates in the ISO, which ratifies and endorses standards from a global perspective. Galdos brings expertise in geographical information and web services to these groups, and takes away an understanding of the standards that its customers seek to meet and adhere to in their businesses.
