This paper discusses the total structure of a management information system of the urban red line in planning based on embedded GIS.

Meanwhile, the digltalization of the using land red line in planning administration is a necessary part of the digital city construction.

But the traditional design of road red line layout cannot keep up with the development of the modern cities.

By analyzing the present status of property right of gas pipeline and facilities within building line,the influence of different attribution of property right on users and gas enterprises and the relevant provisions in the law and code,the faced property right dilemma is discussed,and its solution is put forward.
