Which of the following refers to a Web Based Standard from the OGC?

The Web Feature Service (WFS) is indeed a web-based standard established by the Open Geospatial Consortium (OGC). This standard allows for the request and manipulation of geospatial features over the web. With WFS, users can access geographic feature data securely, enabling them to retrieve, modify, and interact with vector data from different sources.

WFS supports various operations, such as retrieving features based on spatial queries, which makes it instrumental in web mapping applications and services that require dynamic and interactive access to geographic information. The standard facilitates interoperability among diverse GIS platforms, allowing users to query and integrate spatial data seamlessly.

In contrast, while Geopackage, Shapefile, and GeoJSON are important data formats used in GIS, they do not specifically represent web-based standards set by the OGC for serving data over the internet. Geopackage is a format for storing geographic information in a single file, Shapefile is an older vector data format, and GeoJSON is a format for encoding a variety of geographic data structures, primarily used in web applications but not an OGC standard in the same sense as WFS. Thus, WFS is the correct answer.
