| 520 | |a This paper examines OpenStreetMap data quality at different stages of a participatory mapping process in seven slums in Africa and Asia. Data were drawn from an OpenStreetMap-based participatory mapping process developed as part of a research project focusing on understanding inequalities in healthcare access of slum residents in the Global South. Descriptive statistics and qualitative analysis were employed to examine the following research question: What is the spatial data quality of collaborative remote mapping achieved by volunteer mappers in morphologically complex urban areas? Findings show that the completeness achieved by remote mapping largely depends on the morphology and characteristics of slums such as building density and rooftop architecture, varying from 84% in the best case, to zero in the most difficult site. The major scientific contribution of this study is to provide evidence on the spatial data quality of remotely mapped data through volunteer mapping efforts in morphologically complex urban areas such as slums; the results could provide insights into how much fieldwork would be needed in what level of complexity and to what extent the involvement of local volunteers in these efforts is required. | ||

Data were drawn from an OpenStreetMap-based participatory mapping process developed as part of a research project focusing on understanding inequalities in healthcare access of slum residents in the Global South. Descriptive statistics and qualitative analysis were employed to examine the following research question: What is the spatial data quality of collaborative remote mapping achieved by volunteer mappers in morphologically complex urban areas? Findings show that the completeness achieved by remote mapping largely depends on the morphology and characteristics of slums such as building density and rooftop architecture, varying from 84% in the best case, to zero in the most difficult site. The major scientific contribution of this study is to provide evidence on the spatial data quality of remotely mapped data through volunteer mapping efforts in morphologically complex urban areas such as slums; the results could provide insights into how much fieldwork would be needed in what level of complexity and to what extent the involvement of local volunteers in these efforts is required.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Africa</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Asia</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">completeness</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">data quality</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">humanitarian mapping</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">OpenStreetMap</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">participatory mapping stages</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">remote mapping and fieldwork</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">slum</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">volunteered geographic information</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Porto de Albuquerque, João</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Troilo, Rafael</subfield><subfield code="e">verfasserin</subfield><subfield code="0">(DE-588)1185716084</subfield><subfield code="0">(DE-627)1665076852</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Tregonning, Grant</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Perera, Shanaka</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ahmed, Syed A.

Analysis of OpenStreetMap data quality at different stages of a participatory mapping process evidence from slums in Africa and Asia |
| abstract |
This paper examines OpenStreetMap data quality at different stages of a participatory mapping process in seven slums in Africa and Asia. Data were drawn from an OpenStreetMap-based participatory mapping process developed as part of a research project focusing on understanding inequalities in healthcare access of slum residents in the Global South. Descriptive statistics and qualitative analysis were employed to examine the following research question: What is the spatial data quality of collaborative remote mapping achieved by volunteer mappers in morphologically complex urban areas? Findings show that the completeness achieved by remote mapping largely depends on the morphology and characteristics of slums such as building density and rooftop architecture, varying from 84% in the best case, to zero in the most difficult site. The major scientific contribution of this study is to provide evidence on the spatial data quality of remotely mapped data through volunteer mapping efforts in morphologically complex urban areas such as slums; the results could provide insights into how much fieldwork would be needed in what level of complexity and to what extent the involvement of local volunteers in these efforts is required.

Data were drawn from an OpenStreetMap-based participatory mapping process developed as part of a research project focusing on understanding inequalities in healthcare access of slum residents in the Global South. Descriptive statistics and qualitative analysis were employed to examine the following research question: What is the spatial data quality of collaborative remote mapping achieved by volunteer mappers in morphologically complex urban areas? Findings show that the completeness achieved by remote mapping largely depends on the morphology and characteristics of slums such as building density and rooftop architecture, varying from 84% in the best case, to zero in the most difficult site. The major scientific contribution of this study is to provide evidence on the spatial data quality of remotely mapped data through volunteer mapping efforts in morphologically complex urban areas such as slums; the results could provide insights into how much fieldwork would be needed in what level of complexity and to what extent the involvement of local volunteers in these efforts is required.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Africa</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Asia</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">completeness</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">data quality</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">humanitarian mapping</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">OpenStreetMap</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">participatory mapping stages</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">remote mapping and fieldwork</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">slum</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">volunteered geographic information</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Porto de Albuquerque, João</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Troilo, Rafael</subfield><subfield code="e">verfasserin</subfield><subfield code="0">(DE-588)1185716084</subfield><subfield code="0">(DE-627)1665076852</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Tregonning, Grant</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Perera, Shanaka</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ahmed, Syed A.
