Download files from OpenStreetMap


I’m new in using InVEST and I’ve never focused on large areas. For instance, I am trying to download from OSM the boundaries of the Zhejiang county (China), as well as its roads. However, the area is very large, and I’m not sure how to do it. Has anyone a suggestion (like a video) that can help me? I’m using QGIS 3.4.0

Thank you

There are some OSM plugins for QGIS that you might find useful. I haven’t used them recently enough to provide specific guidance though.
