Indoor Accessibility Features

Within our AccessibleMaps Project, we created a database in which we gathered and compared 3 lists containing indoor accessibility features. One list was compiled by us from a literature review. The second list contains relevant OpenStreetMap (OSM) tags and keys (© OpenStreetMap contributors). And the third list contains A11yJSON accessibility criteria.


A dump of our database, in comma separated values (.csv) format, can be downloaded here (note: the values are separated by semicolon):

A pdf version of the alignment table from the database, which contains a comparison of all 3 sources, can be downloaded here:

You can also only download our list of indoor accessibility features gathered from literature (the first list in the database), in pdf format:
