53. Working with GeoContext Data¶

In this article we explain the concept of the GeoContext platform and how layers are published to it in BIMS.

53.1 Creating a GeoContext Collection¶

A GeoContext collection is a set up web map services that can be queried in order to discover habitat or other relevant spatial data for a site.

From GeoContext collection admin page click Add collection button to create a new collection

Fill out the required fields :

• Key - Key of the collection
• Name - Name of the collection

Click Save when you're done

53.2 Adding a GeoContext Group¶

A GeoContext group is a subset of layers from a GeoContext collection that form a logical group, usually based around a theme such as temperature, political regions etc.

53.2.1 Adding groups to existing collection¶

• From the GeoContext Collection admin page, open the collection that you want to add groups to.
• From the Context groups section click Add another collection group link
• Find existing group that you want to add to the group.
• If you want to create a new group, click + sign next to the dropdown. See Adding new Group to learn how to create a new group from scratch.

You can arrange the group order as follows:

• Update the order text manually
• Or move the group by dragging the move item icon that is located on the far right before the x sign

In order to remove group from the group just click the x sign

53.2.2 Adding a new Group¶

You can create a new group from the context group page or directly from layer admin page.

In order to create new group you need to fill out the required fields:

• Key - Key of the context group, this will be used in the bims to fetch the GeoContext data via API
• Name - Name of the group
• Group Type - Type of the group to determine the UI, choose Graph if this group depicting data over a time period. (e.g. monthly average temperature )

See other existing groups for guidance.

53.3 Adding a layer to a GeoContext group¶

In this sectio we describe how you add a layer to a GeoContext group. A layer is a Web Mapping Service intended to make spatial information available over the internet, covering a specific thematic topic e.g. average annual temperature in March

53.3.1 Adding Layers to an Existing GeoContext Group¶

• From the GeoContext group admin page, open the group that you want to add layers to.
• From the Context group services section click Add another context group service link
• Find existing layer that you want to add to the group.
• If you want to create a new layer, click + sign next to the dropdown. See Adding new Layer to learn how to create a new layer from scratch.

You can arrange the layer order as follows:

• Update the order text manually
• Or move the layer by dragging the move item icon that is located on the far right before the x sign

In order to remove layer from the group just click the x sign

Click Save when you're done updating the group.

53.3.2 Adding a new Layer¶

You can create a new layer from the context group page or directly from layer admin page.

In order to create new layer you need to fill out the required fields:

• Key
• Name
• Url - Url of the layer service, e.g. if you use Geoserver then you can try following link : {geoserver_host}/geoserver/wfs
• Query Type - Query type of the layer, usually we use WFS
• Layer name - Required name of the actual layer/feature to retrieve (Property name).
• Layer typename - Layer type name to get the context.
• Service version - Version of the service (e.g. WMS 1.1.0, WFS 2.0.0).

See other existing layers for guidance.
