+### QGIS
+
+[QGIS](https://qgis.org/) supports OGC API - EDR via the [EDR plugin](https://plugins.qgis.org/plugins/edr_plugin/). You can install the plugin directly from the QGIS Plugin Hub, by going to `Plugins->Manage and Install Plugins` on the top level menu.

+
+You can access the plugin through an entry on the plugin menu.

+
+The first thing to setup is the server url. Use the url of the Landing Page here: `http://localhost:5000/`
+
+!!! tip "You should also start by defining the folder where you would like the data fetched by the plugin to be downloaded"
+
+![](../assets/images/edr-plugin3.png){ width=100% }
+
+The combo box will be populated with all the collections available on that server. Select the EDR collection: `International Comprehensive Ocean-Atmosphere Data Set (ICOADS)`.
+
+!!! tip "You may safely ignore the warnings displayed here"
+
+![](../assets/images/edr-plugin4.png){ width=100% }
+
+The data query combo box will be populated with the data query types available for this collection; in this case: position and cube. You may select the cube query and then click the button to set the spatial extent of that query. A new dialog will open, displaying multiple options to define the spatial extent. You may choose the `Draw on canvas`, to draw a rectangle in the map view extent.
+
+![](../assets/images/edr-plugin5.png){ width=100% }
+
+You can close this dialog and run the query. The plugin will fetch all the data available that fits into this query and display it as a layer group.

 À primeira vista, a coleção `icoads-sst` aparece como uma coleção normal OGC API - Coverages. Olhe um pouco mais de perto para a descrição da coleção, e note
 que há uma chave 'parameter_names' que descreve os nomes dos parâmetros EDR para as consultas da coleção.

+O [QGIS](https://qgis.org/) dá suporte à OGC API - EDR através do [plugin EDR](https://plugins.qgis.org/plugins/edr_plugin/). Pode instalar-lo directamente através do Hub de plugins do QGIS, indo a `Plugins->Gerir e instalar Plugins` no menu de topo.

Pode seleccionar a query do tipo cubo e carregar no botão que permite definir a extensão espacial da query. Um novo diálogo irá abrir, mostrando as diferentes opções para definir a extensão espacial. Pode escolher `Desenhar no canvas`, para desenhar um rectângulo no extent da map view.
