“…Flood simulation software, such as MIKE (https://www.mikepoweredbydhi.com/), HEC (Hydrologic Engineering Center, https://www.hec.usace.army.mil/), FLO‐2D (https://flo-2d.com/), and Delft 3D (https://oss.deltares.nl/web/delft3d/), can be used to calculate the extent, flow velocity, and water depth. This information is overlaid with capacity/resource maps and social maps on GIS platforms to analyze the risk level of houses and roads, and then the final spatial distribution and accessibility are presented through map symbols and colors (Liu & Wu, 2018; Meyer et al, 2012; Ntajal, Lamptey, Mahamadou, & Nyarko, 2017; Symonds et al, 2016; Thakur, Parajuli, Kalra, Ahmad, & Gupta, 2017; Waldman et al, 2017; Wu, Liu, & Chen, 2013). However, cartographers and disaster management professionals guide the investigation and design of disaster maps and their thematic focus, which can often lead to the contents of disaster maps not matching the requirements of the public, and the representation methods cannot be easily understood (Holub & Fuchs, 2009; Meyer et al, 2012).…”
