| - | Most of the OGC standards are based on a generalized architecture captured in a set of documents collectively called the ''Abstract Specification'', which describes a basic data model for [[geographic]] features to be represented. Atop the Abstract Specification is a growing number of specifications, or [[standardization|''standards'']], that have been (or are being) developed to serve specific needs for [[interoperability|interoperable]] location and geospatial technology, including GIS. | + | * [[Web Map Service|WMS]] - Web Map Service: mapas em forma de imagens. |
