Over the past two decades, there has been a significant growth of interest in participatory mapping approaches in various research fields. However, their application in studying the effects of outdoor lighting on perceived urban experiences is relatively recent and limited. This paper aims to verify the capability of the Public Participation GIS (PPGIS) to access residents' location-specific knowledge and perceptions of outdoor lighting through an initial exploration of mapped places. It focuses on perceived overall lighting quality (POLQ) and perceived brightness (PB) as attributes for comparing mapped places. Additionally, the paper discusses participants' written feedback regarding the PPGIS survey. The findings reveal notable differences between areas with higher reported POLQ and PB, compared to those with lower POLQ and PB. Furthermore, a strong positive correlation between POLQ and PB attributes was found. Participants' feedback was predominantly positive. These results highlight the potential of PPGIS in future research on outdoor lighting.
