The core of new infrastructure is the construction of digital infrastructure. Currently

the research and development of three-dimensional digital technology in the field of infrastructure in China is relatively insufficient.Based on the development of computer graphics

the three major technologies of BIM

GIS

and GIM were formed the latest. The construction of digital standards for power grid engineering survey can refer to the problems encountered in the application of BIM and GIS

as well as the background and basic technical route for establishing relevant standards. This article starts with the IFC standard established by BIM and the geospatial information standard developed by GIS. It analyzes the impact of BIM related standards on the construction of digital standards for power grid engineering survey and the current status of geological 3D modeling standards. Based on the characteristics of digital power grid engineering survey

it analyzes the content and requirements involved in the construction of digital standards for power grid engineering survey

and explores the most basic object classification and data format standard construction scheme.
