Redraw a stand boundary after thinning, split off a harvest block or merge two compartments. Neighbouring stands follow every change.
vectorstream is a topology-aware geometry editor for web maps. In forestry and land management, stands and compartments are stored with shared borders, so a boundary redrawn after a harvest or a survey changes both adjoining stands. Harvest blocks are split off existing stands, rides and tracks are drawn as lines, and the stand map imports and exports as GeoJSON.
Use cases
Stands are outlined over a basemap and checked on the ground. When a boundary is corrected, the stand on the other side of the line has to change with it.
A harvest block is carved out of one or more stands, and access is planned along rides and tracks. Planners draw the block, check where it meets its neighbours and adjust it before work is scheduled.
Larger estates group stands into compartments and compartments into management units. A layer tree mirrors that structure, and the whole estate exports as one GeoJSON file.
Why topology
Stand maps that store every outline separately grow slivers along each boundary that was ever edited. A shared edge has only one position, so neighbouring stands cannot drift apart.
Operations planning goes through several drafts. Undo restores each earlier stand layout exactly, so a planner can test a block boundary and step back without repair work.
Inventory and planning tools trade forest data as files. GeoJSON import with a geometry check and GeoJSON export keep the stand map portable between them.
How it works
Import stands and compartments as GeoJSON. The geometry check flags broken shapes.
Redraw stand borders after a survey or a harvest. Each border moves once for both stands.
Split off harvest blocks, take retention strips off the block edge and draw access along the rides.
Export the updated stand map and the operation plan as GeoJSON.
