The evolution of public participation GIS (PPGIS) barriers in spatial planning practice

Over the last three decades, PPGIS practices have shifted from a paper to digital format and have become cheaper, more user-friendly, and more versatile. The literature recognizes the potential of PPGIS, but researchers also note that the impact of PPGIS in practice is not yet pronounced. This study seeks to identify the barriers that hinder...

Community Mapping Supports Comprehensive Urban Flood Modeling for Flood Risk Management in a Data-Scarce Environment

In this paper we demonstrate a framework for urban flood modeling with community mapped data, particularly suited for flood risk management in data-scarce environments. The framework comprises three principal stages: data acquisition with survey design and quality assurance, model development and model implementation for flood prediction. We...

Community mapped elevation through a low-cost, dual-frequency GNSS receiver: A performance study in Delft (the Netherlands) and Dar es Salaam (Tanzania)

Heavy rainfall, combined with expanding (unplanned) urban settlements in flood prone areas, expose Dar es Salaam (Tanzania) to the risks of flooding. The urbanisation is so rapid in many areas that it is not beneficial to carry out expensive surveys which are quickly out of date. The work carried out by community-mapping project Dar Ramani Huria...

Community mapping for flood modelling: A case study of the Ramani Huria community mapping project in Dar es Salaam

The current intensification of the hydrologic cycle, in combination with expanding settlements in flood prone areas, makes an increasing share of the global population exposed to flood risks. Many parts of the world are, however, still lacking the data needed for flood risk management and risk reduction. The recent development of information and...
