| Abstract: | According to the inseparability of space, time and material movement, this paper proposes a mathematical model of material existence, and points out that, the non-empty space and the non-negative time are sufficient conditions for material existence. The paper also probes into the law of temporal evolution during the time course, deduces the mathematical model of dynamic change of geo-objects by introducing the concept of different and same place point set, and proves logic certainty of dynamic feature and evolution in cartographic area. |

| Keywords: | existence point set of different places state dynamic geo-object mathematical model |
