PMAP webinar Tuesday November 14 on Novel technological approaches in PPGIS research

Welcome to join PMAP webinar Tuesday 14th November, 2023 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)!

D.Sc. Kamyar Hasanzadeh and PhD Silviya Korpilo will present on Novel technological approaches in PPGIS research.


Kamyar Hasanzadeh is a lecturer in Geoinformatics at the Department of Geosciences and Geography, University of Helsinki. His research is mainly focused on the analysis and modelling of various geospatial data including PPGIS.







Silviya Korpilo is a post-doctoral researcher at the Department of Geosciences and Geography, University of Helsinki. She generally studies human-nature interactions in cities from a socio-ecological-technological systems perspective and particularly how participatory GIS methods can support planning and management of urban green spaces. Her research interests include multisensory methods for studying human experiences in urban nature, environmental psychology, and soundscape research. Silviya is currently working in the ERC funded GREENTRAVEL project that investigates the quality, availability and wellbeing impacts of green urban travel environments. The study employs experimental designs in laboratory and in-situ settings, and modern technologies like Virtual Reality and wearable sensors.

Online lecture on co-creating participatory geoweb tools with vulnerable communities by Jon Corbet on 13 September 2023

Join an online lecture by Jon Corbet on September 13th at 2:30-3:30 pm (UTC+02:00, Eastern Europen Summer Time)

Dr. Jon Corbet will give a seminar lecture in Helsinki on 13 September, but there is a chance to follow it also online. Join us at 2.30-3.30 UTC +02:00 time. Please find the lecture abstract below.

“Bridging the Gap – Co-Creating Participatory Geoweb Tools with Vulnerable Communities”

Since the 1970s, participatory mapping has been employed by academics, civil society, and government as a tool and process to engage with and gain insight from non-experts regarding their knowledge, connections, and experiences in relation to a place. This technique is frequently utilized in research with vulnerable communities, including Indigenous Peoples. In this presentation, I will firstly define the term “vulnerable communities,” secondly provide some personal context of my relationship to participatory mapping and its recent developments, thirdly give three examples of participatory mapping projects that we have conducted with Indigenous communities in Canada, and finally discuss some of the challenges associated with their design, development, and sustainability.

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.
