Abstract
Studies on society and the environment interface are often based on simple questionnaires that do not allow for an in-depth analysis. Research conducted with geo-questionnaires is an increasingly common method. However, even if data collected via a geo-questionnaire are available, the shared databases provide limited information due to personal data protection. In the article, we present open databases that overcome those limitations. They are the result of the iTre-es project concerning public opinion on the benefits provided by trees and shrubs in four different research areas. The databases provide information on the location of trees that are valuable to the residents, the distances from the respondents’ residence place, their attitude toward tree removal, socio-demographic variables, attachment to the place of life, and environmental attitudes. The presentation of all these aspects was possible thanks to the appropriate aggregation of the results. A method to anonymize the respondents is presented. We discuss the collected data and their possible areas of application.
Highlights
Summary In geoinformation, one of the most promising approaches developed since the 1990s is Public Participation Geographic Information Systems (PPGISs), which allow inhabitants to be included in the decision-making process using maps
This belongs to the Computer-Assisted Web Interviewing (CAWI) group of methods based on the softGIS methodology, which concentrates on collecting spatial information in a user-friendly way with interactive maps [2]
PPGISs provide a methodology for many applications related to the effective management of urban spaces [3], including environmental planning [4]
Summary
The geo-questionnaire contained seven sections with topics for which respondents could express their opinions about trees in their vicinity and provide information about themselves and their place of residence: Section 1—Data sheet—information about the respondent: Data included information on gender, age, and education. All of these questions were single-choice questions. Coordinates of the hexagon centroids in which the indicated new trees are located Distance of the indicated tree from the indicated place of residence The selected ecosystem service for the indicated single new tree; n is the maximum number of new trees indicated by the respondents: GDAPOZ19 (n = 5), RACNYS19 (n = 22), GDAPOZ20 (n = 111)
