1. Introduction
This document defines specific DGIWG requirements, recommendations and guidelines for implementations of the ISO OGC Web Map Service standard which is based on ISO
19128:2005 Web Map Server Interface OpenGIS Web Map Server Implementation Specification 1.3.0.
A Web Map Service WMS produces maps of spatially referenced data dynamically from geographic information.
The OGC WMS Interface offers 3 Operations: GetCapabilities mandatory: Allows for obtaining Service Metadata
GetMap mandatory: Returns a map GetFeatureInfo optional: Provides additional information about features in the pictures of
maps that were returned by previous GetMap requests The WMS Implementation Specification defines two conformance classes, “Basic WMS” and
“Queryable WMS”. The Basic WMS supports the mandatory GetCapabilities and GetMap operations requests and
responses whereas the Queryable WMS supports all Basic WMS operations and the GetFeatureInfo operation.
Software implementations that claim to be conformant with the DGIWG WMS profile shall support the Queryable WMS, as well as the specifically defined requirements in this
document.
The DGIWG WMS profile is written in such a way that it references the different operations and parameters of the base standard and then defines specific requirements for software
implementation.

2. Scope
This document defines specific DGIWG requirements, recommendations and guidelines for implementations of the ISO OGC Web Map Service standard which is based on ISO
19128:2005 Web Map Server Interface OpenGIS Web Map Server Implementation Specification 1.3.0.
3. Conformance
This document establishes one conformance class: DGIWG WMS. Annex A lists the conformance abstract tests which shall be exercised on any software artefact claiming to
implement a DGIWG WMS profile.
DGIWG WMS Profile conformance class defines requirements for WMS servers allowing distribution of geographic data in a military environment.
