Lay out lease areas across landowner parcels, take exclusions off the site edge and place array blocks, then export the whole layout as GeoJSON.
vectorstream is a topology-aware geometry editor for web maps. Renewable energy developers use it to plan sites: lease areas follow landowner parcels and share their borders, exclusions along the site boundary are taken off with the difference tool, and solar array blocks are drawn, copied and rotated into place. The layout is exported as GeoJSON for land, permitting and design teams.
Use cases
A project site is put together from parcels owned by different landowners. Lease areas follow those parcels, and when an option boundary is renegotiated the neighbouring lease area changes with it.
Rights of way, wetland margins and other constraints along the site boundary are taken out of the site. The difference tool removes a drawn exclusion that reaches across the outer edge and leaves the remaining site as its own polygon, ready for layout.
Solar blocks are repeated rectangles turned to the orientation of the site. Turbines are points, cables and tracks are lines, and all of them sit on the same map as the leases.
Why topology
Lease areas share boundaries with each other and follow parcel lines. Stored once, a renegotiated boundary updates both leases, so the land plan never contradicts itself.
Site layouts go through many revisions. Exact undo and documents saved automatically in the browser let a developer compare layouts without losing the last good one.
Land, permitting and engineering teams each work in their own tools. A GeoJSON export of leases, exclusions and blocks gives all of them the same geometry.
How it works
Import landowner parcels and known constraints as GeoJSON.
Merge or split parcels into lease areas that share their borders.
Take exclusion strips and access corridors off the site edge.
Place array blocks, turbines and cable routes, then export the layout as GeoJSON.
