This repository aims to assess the damage caused by the devastating earthquakes that hit Turkey and Syria on Feb 6, 2023. Here, we provide pre & post disaster satellite images acquired from Planet, as well as damaged buildings detected using Chooch AI Inference Engine (www.chooch.com).
Pre & post disaster satellite images spatially matched are provided under ./data_matched/
directory.
The files_info.csv
contains useful information and paths to image pairs.
The image pairs are grouped by city and district such that each pair can be accessed as:
{city}/{district}_{id}/
-- {...}_pre.jpg
-- {...}_post.jpg
-- {...}_pre.tif
-- {...}_post.tif
-- {...}_result.jpg
-- {...}_result.json
.tif
files contain geospatial information. .tif
files and .jpg
files have the same image content.
For some pairs, our preliminary results that compare pre&post images are provided as _results.jpg
and _results.json
.
Each json has two components, raw_results
and changes
, where
raw_results
contain the original predictions for'A'
&'B'
images andchanges
contain the predictions grouped by class name and belonging to'only_A','only_B','common_A','common_B'
where in this case A
refers to pre-disaster and B
refers to post-disaster buildings. The objects listed under 'only_A'
are destroyed buildings.
The images are shown side by side (or top/bottom, depending on aspect ratio) and the bounding boxes are drawn in two colors, such that:
- blue for common (undamaged or minor damage) buildings
- red for objects that are present only in pre disaster image, therefore buildings with major damage or destroyed.
