Web Map Specification

Webmap

The web map data lists the basemap, operational layers, and bookmarks to be used in the web map. It also contains information about popup windows and layer styling overrides to be used in the web map. A version property allows you to supply the version of the web map JSON format being used.

Properties

Property Details
applicationProperties Viewing and editing properties of the webmap.
authoringApp [Required] String value indicating the application that last authored the webmap.
authoringAppVersion [Required] String value indicating the version number of the application that last authored the webmap.
background Defines the appearance for the background of the map.
baseMap [Required] Basemaps give the web map a geographic context.
bookmarks A bookmark is a saved geographic extent that allows end users to quickly navigate to a particular area of interest.
mapRangeInfo Map range information.
operationalLayers Operational layers contain business data which are used to make thematic maps.
presentation A presentation consists of multiple slides. Each slide has a different title, extent, basemap, layers, etc.
referenceScale A floating-point number representing the reference scale which map symbols are drawn relative to. The number is the scale's denominator. When the reference scale is 0, symbols are always drawn at the same size regardless of the map scale. The referenceScale is only used for Feature Layers that have scaleSymbols:true. Not all applications or layer types support referenceScale yet. In particular, ArcGISOnline will not use the referenceScale when drawing symbols in the browser.

tables Root element in the web map specifying an array of table objects.
version [Required] Root element in the web map specifying a string value indicating the web map version.
