This volume provides a framework for evaluating geospatial software for participatory mapping. The evaluation is based on ten key indicators: ethics, cost, technical level, inclusiveness, data accuracy, data privacy, analytical capacity, visualization capacity, openness, and accessibility (i.e., mobile friendly or offline capabilities). Each application is evaluated by a user and cross analyzed with specific case studies of the software's real-world application. This framework does not discriminate against assessing volunteered geographic information (VGI) applications, as a form of participatory mapping, in circumstances that its application is spearheaded by underrepresented groups with the intent to empower and spark political or behavioral change within formal and informal institutions. Each chapter follows a strict template to ensure that the information within the volume can be updated periodically to match the ever-changing technological environment. The book covers twelve different mapping applications with the goal of creating a comparative evaluation framework that can be easily interpreted by convening institutions and novice users. This will also help identify gaps in software for participatory mapping which will help to inform application development in the future and updates to current geospatial software.
