| - | ====== Browsing, searching and downloading contents from SmartDublin ====== | + | ===== Uploading the data to the Geoserver and Datastore ===== |
| + | To display a map, the data needs to be available in the Geoserver and the Datastore. | ||
| + | * Click on the (KML or GeoJSON) resource and there should now be a link to **“Import GeoData”** | ||
| + | * Click on this link to upload the data to the Geoserver and the Datastore | ||
| + | {{ :publisher:upload_to_geoserver.jpg?600 |}} | ||

| - | * Users visiting SmartDublin to explore data | + | As you can see, this map is not very useful. You may want to style it, that is, use CMS styling to improve the way it displays. For Dublinked we are going to use common styling for harmonized datasets across the local authorities so you may be able to just [[publisher:copy_styling_from_existing_map|copy an existing style from a similar dataset]]. |
