Once you create a Vector Work and add a Shapefile to it, the thumbnail for the vector data is automatically created. It’s viewable in the Summary page and directly downloadable from Fedora.

Display Vector

A display derivative is a derivative produced by GeoConcerns for loading into external software such as Geoserver. These derivatives can be used to visualize the dataset in a web mapping applications like OpenLayers and Leaflet. Datasets are re-projected into WGS 84 and converted into a standard file format. Geoblacklight makes use of display derivatives for previewing data.

The vector data are also projected into a standard projection (EPSG:4326) and saved as a Shapefile.

Direct download to Display Vector


This Display Vector is then uploaded and registered into your GeoServer catalog.

GeoServer Workspaces

You will need to create two workspaces: “public” and “restricted”. Login as admin with password geoserver to http://localhost:8181/geoserver

GeoServer Workspaces

There’s a new Data Store that holds your Display Vector Shapefile:

GeoServer Workspaces

There’s a new Layer that renders the Vector data in your Data Store:

GeoServer Workspaces

You can also preview your Vector data:

GeoBlacklight Metadata

Finally, if you modify the Vector Work URL by adding /geoblacklight to it, you will receive your metadata as a GeoBlacklight Schema document that you can ingest into your GeoBlacklight instance.

GeoBlacklight Export


The works you created in GeoConcerns should now be available to view in the included Geoblacklight application. http://localhost:3001
