Abstract: The construction status of highway network is an important indicator to reflect the development of regions.It has important reference value of analyzing the construction status of highway network in Shaanxi province to study the regional development in Shaanxi province.Based on the 10 m resolution remote sensing image of 2022,this paper has realized the extraction of roads in Shaanxi province in 2022 through the joint application of PIE-Engine AI platform and ArcGIS PRO software,and analyzed the construction status of the road network in Shaanxi province according to the parameters of road mileage,road density and so on.The results show that there is a strong correlation between the road network construction and economic and geographic features in Shaanxi province,and the road network shows an overall trend of focusing on Xi'an city,the capital of the province,and gradually spreading outward.The results of this paper can provide effective data support for regional development research in Shaanxi province.
