In general, the occurrence of uncertainties in producing geographic data is inevitable. However, most studies concentrated solely on assessing the classification accuracy and neglecting the inherent uncertainties. Our research analyses the impact of uncertainties in measuring the accuracy of OBIA-based slum detection. We selected Jakarta as our case study area because of a national policy of slum eradication, which is causing rapid changes in slum areas. Our research comprises of four parts: slum conceptualization, ruleset development, implementation, and accuracy and uncertainty measurements. Existential and extensional uncertainty arise when producing reference data. The comparison of a manual expert delineations of slums with OBIA slum classification results into four combinations: True Positive, False Positive, True Negative and False Negative. However, the higher the True Positive (which lead to a better accuracy), the lower the certainty of the results. This demonstrates the impact of extensional uncertainties. Our study also demonstrates the role of non-observable indicators (i.e., land tenure), to assist slum detection, particularly in areas where uncertainties exist. In conclusion, uncertainties are increasing when aiming to achieve a higher classification accuracy by matching manual delineation and OBIA classification.<\/jats:p>","DOI":"10.3390\/rs9111164","type":"journal-article","created":{"date-parts":[[2017,11,13]],"date-time":"2017-11-13T11:12:36Z","timestamp":1510571556000},"page":"1164","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["Coupling Uncertainties with Accuracy Assessment in Object-Based Slum Detections, Case Study: Jakarta, Indonesia"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6889-0220","authenticated-orcid":false,"given":"Jati","family":"Pratomo","sequence":"first","affiliation":[{"name":"Faculty of Geo-Information Science &amp; Earth Observation (ITC), University of Twente,  7514 AE Enschede, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1915-2069","authenticated-orcid":false,"given":"Monika","family":"Kuffer","sequence":"additional","affiliation":[{"name":"Faculty of Geo-Information Science &amp; Earth Observation (ITC), University of Twente,  7514 AE Enschede, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9634-3849","authenticated-orcid":false,"given":"Javier","family":"Martinez","sequence":"additional","affiliation":[{"name":"Faculty of Geo-Information Science &amp; Earth Observation (ITC), University of Twente,  7514 AE Enschede, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Divyani","family":"Kohli","sequence":"additional","affiliation":[{"name":"Faculty of Geo-Information Science &amp; Earth Observation (ITC), University of Twente,  7514 AE Enschede, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,11,13]]},"reference":[{"key":"ref_1","unstructured":"Open Working Group SDG (2014).
