This group contains a set of Esri vector basemaps that are available for use in ArcGIS Online. The group contains both web maps and tile layers. The Esri vector basemaps are currently in beta release. For several years, Esri has made available a suite of basemaps that can be used through ArcGIS Online and other apps to create maps and apps. These multi-scale basemaps have been delivered as pre-rendered image tiles (JPG or PNG format) to optimize performance. These basemaps have proven to be very useful and popular, with several billion tiles served each month, but they have some limitations (e.g. users can not customize map, low-res image tiles not optimal for display on high-res devices, etc.). To provide additional options for users, Esri is introducing this new set of vector basemaps (now in beta release). These basemaps are delivered as vector tiles (PBF format) that are rendered client-side based on a style file that is delivered with the vector tiles. The vector basemaps can be displayed in current, desktop web browsers and, in the near future, various desktop and mobile apps. Users are able to customize the look and feel of the vector basemaps by creating custom styles that are used to render the vector tiles. The initial set of Esri vector basemaps, available through this group, includes eight different map styles built using a single vector tile service. The group includes vector basemaps in multiple styles, some that closely resemble existing Esri basemaps (e.g. Streets, Topographic, Light Gray Canvas), and others that are new (e.g. Streets at Night, Navigation, and Imagery Hybrid). The vector basemaps are available as both web maps, which can be used as a basemap for adding other layers, and as tile layers, which can be added to existing maps either as a basemap or overlay layer. This web map provides a detailed vector basemap for the world featuring a neutral background style with minimal colors, labels, and features. This map is currently in beta release. This vector tile layer provides a detailed basemap for the world featuring a neutral background style with minimal colors, labels, and features. This vector tile layer is currently in beta release. This vector tile layer provides a detailed reference layer for the world designed to be overlaid on imagery. This vector tile layer is currently in beta release.
