Systematic Technology Review of OGC Standards and OSGeo Projects

OGC Standards and OSGeo Projects have been widely applied to different kinds of geospatial data and extended for the implementation of geospatial data science environments. However, there’s no review comprehensively summarizing and discussing the progress of these open source technologies for publishing geospatial databases on the Web. The proposed Systematic Technology Review is a stylized version of the Systematic Literature Review, covering the documentation of OGC Standards and OSGeo Projects. To recognize the main topics of each technology in detail, the documentation was analyzed by Latent Dirichlet Allocation using Python. The adoption of the technologies were evaluated based on the number of Github forks and stars, as well as Docker pulls. The latest developments in terms of the OGC Standards for data encoding took place in the GeoPackage. For accessing, processing or visualizing data, the trend was the development of OGC API related standards. However, GML is the OGC Standard for data encoding most implemented in OSGeo Projects, along with Web Services like WMS, WFS, WCS and WPS for accessing, processing and visualizing. The Latent Dirichlet Allocation analyses found eight topics underlying the OGC Standard and OSGeo projects. The keywords of the top four topics were conformance, layer, tile and response.
