Level of detail
- symbols (whether 3D models or 2D symbols)
- 3D object scene layers
For maps we would rather use:
- Multiscale maps (see Author a multiscaled maps)
- Multilevel maps (GIS Cartography book by Gretchen Peterson)
Some concepts behind creating multiscale maps would be:
- scale based symbology
- zoom-level design
- visibility ranges (or scale visibility ranges: https://www.esri.com/arcgis-blog/products/arcgis-online/mapping/using-scale-visibility-ranges-for-symbology-in-arcgis-online-web-maps/)
- generalization: selection and aggregation
