OWGIS (http://owgis.org/), originally Open Web GIS, is an open source software that creates self-contained Web GIS sites with common features used by the scientific community. OWGIS is a Java web application that generates websites by automatically writing HTML and JavaScript code. The websites built with OWGIS are configured by XML files and can accommodate maps with layers served through any map server, such as GeoServer, that complies with the WMSstandard. OWGIS is also capable of constructing Web GIS sites that display 3D data served by the THREDDS servers (Domenico et al., 2006) or the ncWMS servers, using the WMS extension proposed by Blower et al. (2013).
