Module of OpenWebGIS for working with WMS layers. Roman Roads and Provinces.
In OpenWebGIS module for working with WMS layers has been completely redesigned. Look at the Interactive map with WMS layers of Provinces (ca. Ad 303-324) and Roman Roads.
If earlier it was possible to connect the layers with only those servers that support the technology CORS, it is now possible to connect the WMS layers with any servers. Now you can save WMS layers on the server OpenWebGIS for quick access for other work sessions with OpenWebGIS.
There is the brief algorithm of connecting WMS layer to OpenWebGIS:
1 Select the menu item "Layers"->"New Layer from WMS url",
2 In the pop-up window in the corresponding text field enter the server url, for example: http://cga6.cga.harvard.edu/arcgis/services/darmc/roman/MapServer/WMSServer?request=GetCapabilities&service=WMS ,
3 Press the buttons /OK/ or /Get list/,
4 Wait for the list of layers ,
5 Press the /Add Layer/ or if you need to save the layer click checkbox /Save layer on the server/
6 Important: if you add WMS layers and then change the base layer, it may occur an error with redrawing of the map, so select the base layer in advance.
In order to assess the possibility of working with WMS layers I offer to use materials of the remarkable project: The Digital Atlas of Roman and Medieval Civilization (DARMC) http://darmc.harvard.edu/icb/icb.do?keyword=k40248&pageid=icb.page188865
Here one can find the Roman road networks, bridges, aqueducts, the cities and settlements of the empire, Roman military installations, the shrines, mines, and villas that already appeared in the Barrington Atlas and in other similar research tools. But here one can also follow the rise and fall of the main kingdoms, empires, and principalities of medieval Europe, the offices of the great trading federation of the Hanseatic League, the spread of Cluniac monasticism, the medieval universities.
Look at the example of work this WMS layers on the video:
