Accuracy assessment and analysis of ICESat-2 altimetry data in urban areas based on multiple factors
- “The ICESat-2 spaceborne LiDAR height measurement data has the advantages of high accuracy, high timeliness, and low cost, which can provide a data foundation for the construction of urban 3D models. However, this data still lacks systematic accuracy evaluation in urban areas. This article introduces its research progress in the field of urban 3D modeling. The research team has established an ICESat-2 spaceborne height measurement accuracy evaluation system and verified that airborne laser data correction can effectively improve height measurement accuracy, providing a solution for urban 3D modeling and multi-source data fusion.”
