This map viewer page is displaying a Leaflet map using Open Street Map tiles as a basemap. It also is able to load a WMS layer from a HydroShare Geoserver WMS service if the parameters "resourceid" and "layername" are specified from a valid HydroShare resource.
HydroShare and this viewer accomodate common GIS data types such as point, line, polygon, and raster data.
To test this page, include the following paramters in the URL query string in your browser and set a value for each one: 'user', 'resoruceid', and 'layername'
For example here is a full URL with the query string added:
