Our work

When places change, we go and look.

Orthomosaic · Kawasoti · 4.4 cm GSD

Shree Manakamana CF · Kawasoti

A forest, seen stem by stem.

PeopleThe user group and the Division Forest Office, Nawalpur.
QuestionCan the forest be understood at individual-tree level to support its plan?
We addedLow-altitude UAV imagery, field plots, GIS and a locally retrained crown model.
Result6,543 crown detections reported at 4.4 cm (provisional; the four block counts sum to 6,309). 0.73 [email protected] against hand-annotated reference crowns in held-out plots. Detections are not a tree census.
What changedThe stem map and stand statistics went to the user group and the DFO in a form the operational plan can use.
UncertainDetections are not a census; the 0.73 mAP applies to this site and season only.
DataCrown polygons released openly; orthomosaic held for the CFUG.

Trishuli corridor · Nuwakot · 27 Aug 2026

ChangeA glacier collapse sent a flash flood down the Trishuli; the channel through Nuwakot was rewritten overnight.
We didFlew Gairathok, Bidur-10 and Tupche within 24 hours: 16 georeferenced frames, released openly.
What changedThe imagery reached responders while they were still deciding where to go, and stays open for recovery work.
UncertainFrames, not an orthomosaic; coverage is partial and damage counts come from NDRRMA and HOTOSM, not from us.
