Thank you for your feedback and feature request. We currently have a feature request to make it easier to search for maps in-app by Vendor Name in the Map Store (i.e. BaseImage). On the website, avenzamaps.com, you can sort filter maps by Vendor name which you may find useful when searching for BaseImage maps. In the Avenza Maps app, you can search by Vendor via the “Keywords” search box by entering the Vendor’s name.
