The WZDxFeed
object is the root (highest level) object of a WZDx feed. There is one WZDx feed object per WZDx GeoJSON document. The WZDxFeed
is an instance of a GeoJSON FeatureCollection object.
The WZDxFeed
contains high-level information about events ocurring on roadways (called "road events"), primarily work zones, that impact the characteristics of the roadway and involve a change from the default state (such as a lane closure). The WZDxFeed
is the original work zone data exchange feed.
Name | Type | Description | Conformance | Notes |
---|---|---|---|---|
road_event_feed_info |
FeedInfo | Information about the WZDx feed. | Required | This is a WZDx-specific foreign member and is not part of the GeoJSON specification. |
type |
String; "FeatureCollection" |
The GeoJSON object type. For WZDx, this must be the string FeatureCollection . |
Required | This is a GeoJSON property. |
features |
Array; [RoadEventFeature] | An array of GeoJSON Feature objects which represent WZDx road events. | Required | |
bbox |
GeoJSON Bounding Box | Information on the coordinate range for all RoadEventFeatures in the WZDx feed. Must be an array of length 2n where n is the number of dimensions represented in the contained geometries, with all axes of the most southwesterly point followed by all axes of the more northeasterly point. The axes order of a bbox follows the axes order of geometries. |
Optional | This is a GeoJSON property. |
WZDx GeoJSON document (one WZDxFeed
object per file).
