Region gravitation calculation by gravity model approach and visualization based on MapX
Abstract：Gravity model is a model to study the multi-Regional spatial interaction.In order to integrate gravity model with common GIS platforms which have capability of geographical spatial computation,city gravitation matrix among the cities group in the central plain using statistical yearbook of Henan province is calculated,based on the general gravity model.And visualization of the city gravitation matrix by using a programmable GIS mapping control MapX and VC ＋ ＋ 6.0 development tool is presented in detail.The structure and order of city interaction intensity among the cities group in the central plain is brought out.The integration region gravity model data and other geographical spatial data are realized.
