FAQ from QGIS Assistant?
To create a polygon layer in QGIS Assistant, first open the program and click on the 'New Layer' icon in the toolbar. From the dropdown menu, select 'New Shapefile Layer' and then select the 'Polygon' option. You can now specify the layer name and attributes, and draw the polygons by clicking on the map.
To perform a spatial join in QGIS Assistant, first load both the target layer and the join layer into the project. From the 'Vector' menu, select 'Data Management Tools' and then 'Join Attributes by Location'. Select the target layer, join layer, and matching criteria for the join, and then specify the output layer and attribute fields for the joined data.
The projection you should use for your QGIS Assistant project will depend on your data and analysis needs. It is generally recommended to use a projection that preserves distance and area properties, such as an equal area projection or a UTM projection. You can use the 'Project Properties' dialog to change the projection of your project, and use the 'Reproject Layer' tool to convert individual layers to a different projection.
