The working population has increased in cities with urbanization.Providing a supportive built environment reasonable amenities distribution for them is becoming more important.Previous GIS-based approaches to urban planning this issue tend be subjective high labour costs.This paper uses the generative adversarial network (GAN) explore relationship between distributions and morphology, thus effectively predicting visualizing ideal fastgrowing based on condition of well-developed megacities.In research, we take Shanghai, one global China big market, as research sample.First, use Point Interest (POI) data draw heatmap that support workers' daily life collect corresponding city maps.Then, cut into hundreds image pairs training set train GAN model future other cities.To implement model, further maps Jiaxing, second-tier near testing set.Results show our trained can accurately predict its future.The GAN-based prediction could detailed planning.

Assessment of the impact coronavirus infection (COVID-19) on world community, its spread in different countries and regions is far from complete, which confirmed by scale study causes factors morbidity countries. The article devoted to issues integral assessment analysis spatial features inequality social determinants public health. aim was identify influence conditions pandemic basis an incidence example municipalities Kaliningrad Region. authors collected data individual COVID-19 for 2021. list included: 1—the level registered unemployment; 2—coverage children with preschool education number appropriate age; 3—the conditional (minimum) set food; 4—the proportion families need improved housing conditions; 5—the citizens total population who enjoy support communal services; 6—the crimes per 1 000 people; 7—openness accessibility information provision medical services outpatient settings; 8—the comfort providing availability receiving them basis. As criterion assessing morbidity, a composite indicator characterizing (CI) considered. Modeling additive convolution criteria based principles ASPID methodology used as main method. This makes it possible take into account non-numerical, inaccurate incomplete about their priority evaluation studies. Cartographic models geographic systems (GIS) are perform analysis, visualize assess morbidity. revealed trends development region noted increase population. For most municipalities, rates exceed 60 cases people. Against background feature distribution leveling nature within region, accompanied smoothing space inequalities. various variability conclusions previously made that weight affecting changes over time space. contributing health 2021, along conditions, were state crime employment results correlation confirm presence negative between (KP) COVID-19. In general, relationships identified remain moderate strength (0.30 < p 0.49). have shown, use method can provide important authorities at all levels decision-making necessary measures emergency situations epidemic management regions.
