PMAP webinar Tuesday November 1 with Prof. Marketta Kyttä as speaker

Welcome to join PMAP webinar Tuesday 1st November, 2022 at 3:30-4:30 pm CET time (4:30 pm Helsinki, London 2:30 pm, New York 9:30 am, Tokyo 10:30 pm)!

Professor Marketta Kyttä presents on PPGIS in environmental health promotion research.

Marketta Kyttä works as a professor of Land Use Planning at the Department of Built Environment at Aalto University, Finland. Having background in environmental psychology, her interests cover widely human aspects in planning. Her research topics include environments that promote wellbeing and health, active living, child- and age-friendly environments, social sustainability, urban lifestyles, perceived safety and new methods for public participation. She has extensive experience developing and applying PPGIS methods. For example, the so called “softGIS” methodology originates from her research team.

Please join the webinar via Zoom: (no pre-registration required).

In case you have interest to present in PMAP biannual webinar series, please do not hesitate to contact Associate Professor Nora Fagerholm (

Increased interest in comparing PPGIS and social media data

A recent publication by Stahl Olafsson et al. (2022) has explored 19 case sites across Europe to compare perceived landscape values applying and comparing both PPGIS and geolocated social media (Flickr) data.  Authors find more cross-site differences than similarities both in spatial patterns and value types. Most agreement in spatial patterns across the two data sets are found in densely populated landscapes; however, comparison of types of perceived landscape values is challenged by the differing assumptions of each value elicitation technique. The results show that PPGIS elicits a wider spectrum of values, while Flickr mainly elicits relationships to and with landscapes. The authors argue for the complementary potential of both approaches and highlight the strengths and weaknesses of using the two together in landscape research, planning and management.

Webinar by ISPM June 16

Please note the webinar organised by the International Society for Participatory Mapping!

This webinar, to be delivered on 16 June 2022, 13.00-14.30 (Mexico Central time/ CST), presents the efforts of three significant organisations in Latin America, very active in developing the strengths of participatory mapping and critical cartography so as to apply them to support activists in real political, social and cultural urban struggles in the continent.

Two of the presentations will be offered in Spanish and one in Portuguese (with english subtitles in Zoom). More information below.

PMAP webinar #1 recording now online

PMAP webinar next Tuesday

Welcome to join PMAP webinar next Tuesday May 24th 3:30-4:30 pm CET time (4:30 pm Helsinki, London 2:30 pm, New York 9:30 am, Tokyo 10:30 pm)!

Jirka Panek and Ian Babelon will present on 100+ shades of geoparticipation.

Dr. Jirka Panek works as an associate professor at the Department of Development and Environmental Studies, Palacký University in Olomouc, Czech Republic. With background in geography and GIS, he has been enthusiastic about developing participatory mapping methods both in global North and South and has been co-developing participatory platform for collection perceptions about urban environment. Dr. Ian Babelon is Research Fellow at Northumbria University in Newcastle, UK. His PhD investigated the use of digital tools for public participation in urban planning. Recently, Ian, Jirka and colleagues published an article ( reviewing objectives of 25 web-based geoparticipation projects in urban planning.
