Mapping the informal settlements based on Earth observation satellite data has progressed significantly. However, only the two-dimensional representation of the informal settlements is provided by current approaches. As a result, a complete characterization is limited in urban morphology, which can only be obtained through a thorough examination of the vertical settlement extent. Therefore, this study is aimed to identify the types and patterns of vertical morphologies of informal settlements and develop a 3D model of these morphologies for planning decision making using earth observation techniques in Kabul. To synergize various types of data planning and to develop the 3D model, the geographical information system was applied (GIS). A set of urban morphology maps, land surface maps, and building height maps were merged to create Local Climate Zones (LCZs) maps by following the standardized procedure proposed by the LCZ framework to identifying types and patterns of vertical morphologies. Next, the physical difference and locational factor analysis were conducted for identified vertical morphologies. The 3D model is developed at a block level to analyze the vertical morphology types, patterns, and distribution. The 3D model was processed in GIS extension, ArcGIS Pro. The building footprints are manually digitalized using UAV images with 10 cm resolution, and building height information is accessed from UN-Habitat field survey data (MIS data). The procedure ended with a 3D model that shows the types and patterns of identified vertical morphologies. This study used an integrative GIS-based method to analyze various types of planning data for analyzing the vertical urban morphology of informal settlements in Kabul, which is also applicable to other cities with an extensive range of planning information.
