QGIS Plugin · Building Damage Assessment

See the damage
before you reach
the ground.

beaconGIS reads pre- and post-disaster satellite imagery and, building by building, finds every structure and grades its damage — No Damage, Minor, Major, Destroyed — right inside QGIS.

Pick a city, then drop your own GeoTIFF exports into the frame — each city persists locally. Switch the layout from the Tweaks panel (slider · triptych · auto-sequence).

Trained on the world's disasters

Built on the xView2
building-damage benchmark.

The detection and classification models learn from xBD — the largest open dataset of annotated pre/post-disaster satellite imagery — and are fine-tuned to generalize to disasters and regions never seen in training.

What's in the box

A full damage-assessment desk,
docked in your map canvas.

From the first raw tile to a signed-off situation report — beaconGIS keeps the whole loop inside QGIS.

pace with the response.

AOI polygon layer
Region of interest

Score only the ground that matters.

Hand it an AOI polygon layer and beaconGIS clips the analysis to that boundary — a single district, a flood plain, one response sector. Skip the empty ocean and the untouched hills, and finish large scenes in a fraction of the time.

  • Select any polygon layer as your boundary
  • Leave it empty to assess the entire image
  • Dramatically faster on city-scale rasters

Built for reuse

Export once. Brief, archive, and re-train.

Save the vector result as a GeoPackage for GIS work, or a binary GeoTIFF mask to train your own models. Generate a Damage Pattern Analysis, a full SitRep or Response Priorities — and hand them off as PDF, HTML, TXT or CSV.

No imagery? No problem

Pull fresh imagery from inside the plugin.

Drop a latitude/longitude or grab the current map centre, choose a provider and zoom, and beaconGIS fetches high-resolution tiles straight onto your canvas — ready to assess the moment they land.

Dialled in

Tune accuracy against time.

Test-Time Augmentation

4-way TTA squeezes out more accurate predictions when you can spend the extra compute. One checkbox, on or off.

CPU fast mode

No GPU on the laptop in the field? Fast mode runs roughly 8× quicker for a small accuracy trade — assessment doesn't have to wait.

Building separation

A single slider controls how aggressively touching structures are split apart — from dense terraces to sprawling compounds.

Fully on-device

Every model runs locally. Imagery, masks and reports stay on your machine — vital for sensitive incident data.

Native to QGIS

It's a processing panel, not a separate app. Results land as real QGIS layers you can style, query and join like any other.

Four-class taxonomy

No Damage, Minor, Major and Destroyed — the xView2 standard your downstream tools and partners already speak.

Four steps

From raw tiles to a signed-off SitRep.

01

Load imagery

Bring in your before and after RGB scenes — or download fresh tiles from the built-in fetcher.

02

Set the scope

Optionally clip to an AOI polygon, flip on TTA, and set building separation to suit the terrain.

03

Run assessment

beaconGIS localizes every building and grades each one across the four damage classes.

04

Export & brief

Save a GeoPackage or training mask, then generate the report your responders need.
