The Web Map Server Implementation Specification (WMS), originally developed and published by the Open Geospatial Consortium, was finally adopted by ISO as an international standard.
SUAS MapServer supports this specification and a few other services like 3D representation. Geo-data is converted to Well-known Text (WKT) and stored in database management system, retrieved by SUAS upon user request and transferred - optionally compressed - through the Internet for client-side visualization.
