GeoRSS Layer (GeoRSS)

GeoRSS feeds may contain any combination of points, lines, and polygons. Web clients use a GeoRSS to JSON request service. This service returns one to many feature collections with different geometry types. The returned JSON specifies the point, lines, and polygons symbols used to display the features in that layer.

Properties

Property Details
id A unique identifying string for the layer.
layerType String indicating the layer type.
Value of this property must be GeoRSS
lineSymbol Defined by the GeoRSS to JSON request service. If the GeoRSS feed does not have lines, this property is not added to the layer JSON.
maxScale A number representing the maximum scale at which the layer will be visible. The number is the scale's denominator.
minScale A number representing the minimum scale at which the layer will be visible. The number is the scale's denominator.
opacity The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency.
pointSymbol Defined by the GeoRSS to JSON request service. If the GeoRSS feed does not have points, this property is not added to the layer JSON.
polygonSymbol Defined by the GeoRSS to JSON request service. If the GeoRSS feed does not have polygons, this property is not added to the layer JSON.
refreshInterval Refresh interval of the layer in minutes. Non-zero value indicates automatic layer refresh at the specified interval. Value of 0 indicates auto refresh is not enabled.
showLegend Indicates whether to allow map authors the ability to control what layers should be shown in a client's legend.
title A user-friendly string title for the layer that can be used in a table of contents.
type Deprecated, please use layerType.
url The URL to the layer.
visibility Boolean property determining whether the layer is initially visible in the web map.
