what is sar-toolkit fr?

SAR Field Toolkit is a self-hosted, browser-based collection of small tools built for search and rescue teams to process location data. A key point the README makes clear is that every calculation happens entirely inside your own browser, and no data is ever sent to any outside server, which matters for a use case where the locations involved may be sensitive. The toolkit bundles five specific tools. A CSV to KML converter takes a spreadsheet of latitude and longitude, or UTM coordinates, and turns it into a KML file, the format used by mapping tools like Google Earth, with an option to also draw a connecting track line. A GPX cleaner removes the erroneous straight lines that show up in GPS track files when the signal drops out and the device jumps between two distant points. A KML reducer takes a file cluttered with thousands of individual point markers, such as a log from a search aircraft, and replaces them with a single clean track line. A search patterns tool generates standard search shapes, either a creeping line pattern of parallel tracks or an expanding square, and exports them as KML. A search boxes tool generates a grid or radial layout of labelled search sectors as KML, meant for assigning specific zones to different search teams. Running it requires only Docker and Docker Compose. You download the project's docker-compose.yml file, run docker compose up in the background, and then open the tool in a browser at localhost on port 3080, which can be changed by editing the compose file before starting it. Updating to the newest version is done by pulling the latest image and restarting, since the image is automatically rebuilt and published whenever a change is pushed to the project's main branch.
