You can download map packages for later offline use. Map packages must be associated with a survey for you to be able to browse and download them. To learn how to associate a basemap with a survey, see Prepare basemaps for offline use.
You can choose between Basic and Standard map types for the location questions in your survey. Standard is the default and is recommended for most devices. When using Standard map types, you can download tile packages (TPK), vector tile packages (VTPK), and mobile map packages (MMPK).
For devices that encounter performance issues when displaying a map, you can use Basic map types. If Basic map types are being used, you will only be able to use tile packages up to 2 GB in size for offline use. Basic map types are the default on older Android and iOS devices, or you can select them manually in both the field app and Survey123 Connect by browsing to Settings > Map and selecting Basic under Map types.
