OSM Defibrillator Mapping Progress in the 'L' Postal Area

Note: There is currently no licence to use the AED location data from the Ambulance Services in Open Street Map. (Even if there was, many are located only by postcode, so the locations are not always precise.) So you must not make any OpenStreetMap edits based on the circles on the map, or the data in the popups or tables below. The data can be used to inform surveys though.

The blue circles on the map are defibrillator locations from the official lists that haven't been matched to an OSM object. The red, orange and yellow circles are OSM objects that haven't been matched to a defibrillator on an official list (orange for AEDs that may not be available 24/7, yellow for AEDs not generally available for public use, and red for everything else). The green lines represent matches from the official data to OSM objects . For more information see below. Note that there is currently no licence/permission to use the external data directly in OSM, so it can only be used to inform surveys.

The matching works as follows: First we check each Ambulence Service location for an OSM amenity=defibrillator object with a matching postcode, with 2km of the postcode centroid. If any are found the nearest such object is matched. Then we go through all unmatched Ambulence Service locations, and look for any unmatched amenity=defibrillator OSM objects within 150m. If any are found, the hearest is matched. Finally, the previous step is repeated, but with an increased distance limit of 500m. Note that this matching is not perfect, and if there are multiple nearby AEDs, or an EAD is a long way from its postcode centriod, they may not be matched correctly.
