It also has the capability of displaying 4D layers on the maps it creates, as well as the option to download layers in GIS format or as KML files. OWGIS lacks an administration interface as well as a searching engine for geographical data on the web. Nevertheless, OWIGS exceeds ArcGIS online in its features provided to display and style 4D data acquired from ncWMS servers. The only ArcGIS online example, that we knowoff, that has the ability to retrieve data from ncWMS servers (http://dtc-sci01.esri.com/MultiDimWMSViewer/) do not has the possibility to modify color palettes or the color ranges of layers. This example also lacks the option to crate vertical profiles, vertical transects, and time series. These extra features,plus the fact that ArcGIS online license costs thousands of dollars per year, makes OWGIS a good alternative to build WebGIS interfaces,specially for environmental scientists that store their geospatial data as NetCDF files.
