The manifestation of geographical phenomena is the result of the synthesis of several elements. Increased calculation and analysis techniques are demonstrated in collaborative multi-process calculation and coupling, ranging from single-point calculation to distributed coupling calculation, from independent variable mining to large-scale text mining, from spatial analysis to big data, and complex network mining characteristic analysis, as well as the transition from single geographic process calculation to multiple geographic process analysis The research on geographical applications supported by big geodata reflects its fundamental characteristics: continuously refined scales and scopes, gradually extended research objects, and the goal of comprehensive law discovery, for example, using over one million sample coverage and high-density sampling to support the inference of statistical characteristics of group behaviors, using hundreds of thousands of sampling data and multi-factor driving.
