Abstract
An exemplary method for publishing replicated geographic data in a node tree for display in a three-dimensional environment includes ingesting instances, each instance including an instance location and a reference to a geographic model to be displayed at the instance location. The exemplary method also includes determining levels of detail in the node tree for instances based at least on a size of a model referenced by the instances. The exemplary method further includes distributing the instances to a set of nodes in the node tree at the corresponding levels of detail. The exemplary method also includes determining an ancestor node in the node tree for one or more nodes in the set of nodes. The exemplary method further includes generating a collection to be referenced by the ancestor node in the node tree. The exemplary method also includes publishing the node tree with the collection and the instances.
