Abstract:This paper thoroughly analyzes the problems existing in the management of non-powered equipment at airports.It explores the construction ideas for high-precision positioning terminals for non-powered equipment based on Beidou high-precision positioning technology and proposes a refined management model,including the reengineering of the non-powered equipment usage process and the functional architecture of the management platform.Relying on the innovation of equipment and management models based on Beidou high-precision positioning technology,this approach can effectively enhance the level of refined management of non-powered equipment at airports,providing a new direction and perspective for the management of non-powered equipment at various airports in China.

Abstract:Aiming at the problems of fuzzy contribution,unclear accounting scope,and unclear path of digital economy in the field of transportation in China,this paper proposes a method to measure the scale of digital economy in the field of transportation based on a growth accounting account model and a perpetual inventory method.Based on the data of statistical yearbook and input-output table of Jiangsu Province in each year,the paper calculates the scale of digital economy in the field of transportation in Jiangsu Province.The scale of digital economy in the field of transportation in Jiangsu Province is stable and improving,and its overall upward trend is consistent with the upward trend of regional GDP in Jiangsu.

Abstract:Geological spatial information data in geological surveys possesses characteristics such as large quantity,diverse types,and complex structures.Traditional geological survey methods are no longer sufficient to meet the needs of today's engineering projects.This paper,supported by GIS technology,designs a geological survey data service system.The system is aimed at field geological survey personnel and project management personnel.It can realize professional functions such as storage,management,updating,synthesis,querying,analysis and evaluation,and visual expression of massive geological survey data,groundwater monitoring data,as well as related vector and elevation data.In practical engineering cases,the system has received positive feedback,providing assistance for geological workers and aiding decision-makers in judgment.It has high practical value.
