In the current study, a comparative analysis of urban growth based on city center and central business district (CBD) of Antananarivo, the capital city of Madagascar was carried out. Four temporal satellite images of 5 years interval were used to determine the pattern, the process and general conditions of expansion of the urban extents in different directions. Pearson’s chi-square test and Shannon’s entropy measure were used to evaluate the degree-of-freedom and degree of sprawl towards the analysis of urban growth. To combine the previously mentioned statistics, the degree of goodness was used. The comparative analysis shows that there are contradictive results in the derived statistical measures from both considered urban growth centers indicating different conditions of urban growth. Deeper analysis accompanied by the theory of Von Thünen on urban land use support that the CBD is the most appropriate center of growth for the application of the previously mentioned statistical measures for the case of Antananarivo city.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Central business districts,Chi-square tests,Comparative analysis,Degree of freedom,Development policies,Satellite images,Shannon’s entropy,Statistical measures[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1755-1315/389/1/012010[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
