Generated endpoint and junction nodes used to validate corridor topology.
Summary
This internal dataset contains generated endpoint and junction nodes used to validate transmission corridor topology. It supports map maintenance and QA rather than reader-facing infrastructure interpretation.
What It Represents
This point dataset is generated from traced corridor endpoints, inferred junctions, and supporting grid anchors. It helps validate whether the mapped network connects coherently, but it is no longer exposed as a public map control because many nodes are topology artifacts rather than visitor-facing infrastructure.
How To Read It
Use it when maintaining the transmission pipeline: checking whether a line has plausible endpoints, where generated joins are happening, or whether topology is being over-interpreted.
Coverage / Method
The dataset covers 56 point features listed in Map Inventory. Nodes are generated from traced corridor endpoints, inferred junctions, and supporting grid anchors, and are retained for topology QA rather than as surveyed substation inventory.
Caveats
These are internal topology nodes. Some represent real substations or hubs, while others are generated endpoint clusters. Do not read every marker as a surveyed asset.
