Based on the VCAG assessment, WHO will then consider initiating the guidelines development process to support formulation of a recommendation, if warranted. Health value, and provides an assessment of the evidence-base once it has been generated. In order to assist WHO guidelines development groups in developing recommendations on new interventions for vector control, VCAG provides guidance to manufacturers and researchers on developing the evidence base required to inform assessment of public These recommendations, published in WHO guidelines, are essential to ensure the optimal use of scarce resources available for vector-borne disease control. Independent evaluation of the public health value of new interventions for vector control is needed to enable WHO to develop evidence-based recommendations aimed at informing the development of vector-borne disease control strategies by WHO Member States. Process to express interest, and the process of selection. This “Call for experts” provides information about the advisory group in question, the expert profiles being sought, the Group1 = QgsProject.instance().layerTreeRoot().The World Health Organization (WHO) is seeking experts to serve as members of the Vector Control Advisory Group (VCAG). n("native:extractbylocation",Įxtract1 = QgsVectorLayer(save_path, 'My Layer', 'ogr') Save_path = '/home/ben/GIS Files/Vector Data/Aus_state_boundaries/selected.gpkg' # Change path layer1 = QgsProject.instance().mapLayersByName('ne_10m_populated_places_simple') # Change layer name To run this example you must change both the layer names and the file path to the save location. This example saves the result to a file location, then loads it into the project and adds it to a group in the layer tree. The result of this example can be seen below. Group1 = QgsProject.instance().layerTreeRoot().findGroup('group1') Layer2 = QgsProject.instance().mapLayersByName('Aus_state_boundaries') # Change layer nameĮxtract1 = n("native:extractbylocation", This example adds the temporary output layer to a group in the layer tree: layer1 = QgsProject.instance().mapLayersByName('ne_10m_populated_places_simple') # Change layer name To run this example you would need to only change the layer names. You can see in the screenshot how my layer tree is set up. The code example in the question is incomplete so here is a complete, reproducible example which should be self explanatory to any future readers. # Now insert the layer node into an existing group at the desired position (given by integer in first argument) QgsProject.instance().addMapLayer(extract1, addToLegend=False) # Add the layer to project with parameter addToLegend set to False 'OUTPUT': QgsProcessing.TEMPORARY_OUTPUT}) 'INTERSECT': QgsProcessingFeatureSourceDefinition(layer2.id(), selectedFeaturesOnly=True, featureLimit=-1, geometr圜heck=QgsFeatureRequest.GeometryAbortOnInvalid), To do that you can use the code below: extract1 = n("native:extractbylocation", I'm not sure what you mean by "save the temporary layer", because if you want to save the result, don't use a temporary output! But I guess what you actually want is to add the resulting temporary layer to the project, rename it and add it to a group in the layer tree.
