Living Atlas of the World (LAW) is a subset of data available in ArcGIS
You can browse it through livingatlas.arcgis.com or the "LAW Search" group in arcgis.com.
Tile layers
Service type: Tile Map Service (x, y, z), Web Map Tile Service (WMTS) & Esri Tile Layers | Data type: raster or vector
Main purpose: provide context to data & technical performance: storage and load times.
Example: basemaps (satellite, roads, ...), aerial pictures, large data, ...
Feature layers
For spatial raw vector data. Similar to GeoJSON, KML, GPX ... but it is managed through a REST API.
Esri Hosted Feature Layers are optimized, supporting: data tiling, caching, protocol buffers, cartographic generalization, http2, CDNs, and more.
Service type: Esri Feature Layers, Web Feature Service (WFS) | Data type: vector (alphanumberic + shape/geometry)
Main purpose: access, query, and edit raw data interactively
Example: buildings, POIs, roads, live alerts, boundaries, ...
Map Image Layers
Service type: Map Service, Web Map Service (WMS)| Data type: can include both feature and non-feature layers as sublayers
Main purpose: combine the best of raster and vector in a single service
Example: interactive large datasets: demographics by county, large water or traffic models, ...
Imagery Layers
Service type: Esri dynamic imagery layers (a.k.a. raster layers), Web Coverage Service (WCS) | Data type: raster
Main purpose: process and analyze large continuous space/time-varying data.
Example: weather data, land cover, vegetation index, elevation data, slopes, ...
Disclaimer
Remember, we have reviewed the four most common data types of services, but ArcGIS Platform supports many more (scene services, stream service, KML services, geodata services, etc.).
Living Atlas data layers access considerations:
Default layers (~5900): free to access and use (no login required).
Subscription layers (~1000): free to access and use (login required).
Premium layers (~500): paid pers use (demographic layers mainly).
Not all data can be downloaded, read Deployment > Content and data.
