The mapping process was applied to the Dhaka metropolitan area (DMA), a region encompassing both the wards of the Dhaka city corporation (DCC) and the unions of the DMA. The name “Dhaka” is said to come from the dhak tree that was once plentiful in the area, while others believe the name comes from Dhakeshwari, or The Hidden Goddess, to whom a shrine is built. The slum maps require the attribute information available from fieldwork to be useful for targeted planning and policymaking. Dataset Item 5 (Spatial Data). The authors declare that they have no conflict of interests. These data reveal the loss of slum settlements from areas previously containing slum. Shapefiles were drawn using the editor tool. First, a copy of the 2006 slum shapefile was overlaid onto the 2010 Quickbird images. UN-HABITAT (2006) reports that 79% of the population of Bangladesh’s larger cities live in them. Angeles et al. Applications of remote sensing are best able to identify slums through the features of housing density, structure, and roof composition [15, 16]. The fast-growing population has already put tremendous stress on the city, as evidenced by its high rates of poverty, and future concerns include increasing congestion, a higher percentage of unemployment and inadequate infrastructure. For 2010, three of nine scenes were acquired on March 20 [28–30] and six were acquired on April 7 [31–36]. Most Muslims are Sunni, and Ahmadiyya and Shia make up the remainder of the 90%. The dataset presented here can be considered a stepping stone for further research on slums and urban expansion in Dhaka. This rural migration accounted for 60% population growth throughout the 1960s and 1970s. According to UN Habitat, Dhaka is the world’s most crowded city. Various slum classifications exist in the literature, yet there is no universal definition for a slum community or for slum housing. To determine the morbidity status of the urban slum population of the Dhaka city. Tokyo is … About 16 million people live in Dhaka alone and the number is projected to rise to 27 million by 2030. During British rule, schools, townships, and public works were developed, as well as a municipal water system in 1874 and electricity supply in 1878. These data reveal the loss of slum settlements from areas previously containing slum. First, identification is based entirely on visual interpretation and comparison with known slum appearances. The following data were used in determining slum locations and borders:(i)Quickbird satellite images from 2006 (6 tiles),(ii)Quickbird satellite images from 2010 (9 tiles),(iii)2005 census and mapping of slums (CMS),(iv)sample data from slums visited in 2007, 2008, and 2009,(v)Google Earth timescale images,(vi)geolocated amateur photographs from “Panoramio” linked to Google Earth.The Quickbird satellite produces panchromatic imagery at a resolution of 0.6 m. Each image was projected to WGS 1984, UTM Zone 46N. Nonetheless, remote sensing can provide an excellent adjunct or alternative to field surveys of urban environments. Dhaka and the municipalities that make up the Greater Dhaka Area have a total population of over 18 million, and the city has shown a population growth of about 4.2% annually. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. Many city blocks became easier to interpret under different lighting conditions. Due to a slight offset, the 2010 scene georeferencing was adjusted to match the 2006 images using control points. This was performed because the editing process resulted in many thousand overlapping polygons. It stands on a patch of land that was once a barren field, but started to be settled at the end of the 1970s, mostly by people who came to Dhaka in search of work and had nowhere to live. This shapefile is made up of seven separate file formats, each containing different information with regard to the shapefile. ESRI shapefile containing polygons that represent the 91 wards of the Dhaka City Corporation and the 10 unions of the Dhaka Metropolitan Area along with the ward/union boundary shapefile derived from the CMS and adapted to fit with the names of the most recent population and housing census. The output was deemed the final 2010 slum map (Dataset Item 3 (Spatial Data)). STEVE SAPIENZA: Dhaka, the capital of Bangladesh, is one of the world's fastest-growing cities and one of the poorest. For example, the geometric information of the spatial feature itself (e.g., spatial boundary of Dhaka wards and unions) is stored in the “, ESRI shapefile containing polygons that represent the delineations of slums larger than 1 acre in the Dhaka Metropolitan Area as seen in 2006 Quickbird images [, ESRI shapefile containing polygons that represent the delineations of slums larger than 1 acre in the Dhaka Metropolitan Area as seen in 2010 Quickbird images [, ESRI shapefile containing polygons that represent the areas of the slums that exist in Dataset Item 3 (Spatial Data) but do not exist in Dataset Item 2 (Spatial Data) along with the ward/union boundary shapefile derived from the CMS and adapted to fit with the names of the most recent census. Keitel spent two and a half months in Dhaka in spring of 2012, taking photos almost daily. Tobia Lakes, Mobarak Hossain Khan, and Patrick Hostert participated in the design of the paper, helped in guiding the spatial analysis and interpretation, and revised the paper critically. After completion, the additions were joined to the 2006 polygons with the union tool, and the subtractions were deleted with the erase tool. The dataset presented here can be considered a stepping stone for further research of slums and urban expansion in Dhaka. Dataset Item 3 (Spatial Data).
