Daily cadastre is to revise and update the dynamic changes of land distribution, quantity, quality, ownership and utilization.
According to the distribution of land, it can be divided into urban cadastre and rural cadastre. The object of urban cadastre is cities and towns, and the object of rural cadastre is urban suburbs and rural areas. The former adopts the large-scale cadastral map of 1: 500, while the latter adopts the cadastral map of 1: 2000.
