Properties

Field Type Label Description
node Node repeated

List of nodes located in the partition. Nodes are included in the partition that holds their coordinates. Coordinates are inclusive on the southern and western edges of a partition. Partitions always include their southern and western edges and, with two exceptions, do not include their northern and eastern edges. The two exceptions are: (1) A partition whose eastern edge is 180 degrees east longitude includes the eastern edge; (2) a partition whose northern edge is 90 degree north latitude includes the northern edge.
