GeognoSIS SWD
This is the recommended method of adding data layers to your Web Map Layers 8.0 map.
Base layers cannot be added using the GeognoSIS SWD.
Adding data as a GeognoSIS SWD creates a more dynamic connection between the data and Web Map Layers 8.0. It allows you to make edits to the data in the SWD which will then be immediately visible when your Web Map Layers 8.0 site is refreshed.
Before adding a GeognoSIS SWD layer you MUST enable GeognoSIS API for your GeognoSIS instance, this is done in the GeognoSIS manager. For your GeognoSIS instance expand the Web Services and then the Cadcorp Services and then right click API service and select Properties.
In the API Service Properties dialog, Configuration tab, make sure the Enable API Service tickbox is checked:
