OCELL
Forestry-management software that builds a forest digital twin from aerial imagery
The German team OCELL builds a "forest digital twin": using aerial imagery plus multi-source data to reconstruct a whole woodland into a precise virtual model, with every tree's position, species, height, and volume in it. Traditional forest inventory relies on sample surveys plus estimation, with a single count easily taking months; with a digital twin, forestry staff can answer "how much harvestable volume this stand has now" from the office.
Features and use scenarios
The platform covers single-tree-level species and growth recognition, stand-structure analysis, thinning and harvest planning, and damage assessment for storms, pests, and the like. It also incorporates carbon-sink calculation — European forest owners increasingly need to prove to the carbon-credit market how much carbon their forest absorbs, which is impossible without a precise inventory.
It suits forestry operators, forestry authorities, and carbon-credit project developers. Sixty percent of Taiwan's land is forest, and forestry units have long struggled with high inventory costs and long update cycles, so this aerial-plus-AI survey method actually has good reference value for local forest carbon-sink accounting.

Editor's Note
Forest carbon sinks have been much hyped these years, but the real barrier was never the concept — it's 'how do you prove it.' A precise inventory is that entry ticket, and what OCELL really sells is auditability.
FAQ
Does it work for Taiwan's multi-layered mixed forests?
Europe is dominated by planted coniferous forests with relatively simple canopy structures; Taiwan's natural forests have many species and complex layers, making recognition much harder. If adopting, a small-area trial to verify accuracy first is advised.
How does it differ from satellite-imagery interpretation?
Satellite suits viewing large-scale trends, but its resolution struggles to reach single-tree level. Aerial survey costs more but obtains each tree's information; the two are actually complementary rather than substitutes.
