- | * The geospatial formats that Dublinked currently supports in its map viewer are KML and GeoJSON. | + | * The geospatial format that Dublinked currently supports in its map viewer is WMS. This is created when the data publisher loads either a GeoJSON or KML format resource to the Dublinked geoserver. |
+ | * There are two ways to access the map viewer, either from the main menu, or via the preview map created for a WMS resource. These are described below. | ||
- | ==== Start using map viewer ==== | + | ===== [1] Start map viewer from the main menu ===== |
- | Select a dataset of interest that has a resource in WMS format (select WMS format on the datasets selection page). | + | Select Map Viewer on the main menu |
+ | {{ :public:map_explorer_from_main_menu.jpg?600 |}} | ||
+ | Use the Add Data button and the data catalog will now open. From here you can select any data of interest, browsing it either by category or publisher, or using a text search (**NB, exact text match search, eg "bins" will not find "DCC Public bin locations"**): | ||
+ | {{ :public:select_bin.jpg?600 |}} | ||
+ | Use the + symbol to add the data to the map. | ||
+ | {{ :public:select_bin_2.jpg?600 |}} | ||
+ | You will now see the data on the map: | ||

These are the GeoJSON and KML format files that have been uploaded to the Dublinked geoserver, and so have maps available on the site. For this example I selected "DCC Public Bin Locations". | These are the GeoJSON and KML format files that have been uploaded to the Dublinked geoserver, and so have maps available on the site.
