基于CGCS 2000下高原地区地方坐标系的建立分析
|
摘要
针对西南高原地区的地形起伏、地貌复杂等因素对建立基于CGCS 2000的高原地区地方坐标系的影响,采用ALOS World 3D-30m DSM数据来获取区域的地形地貌情况,用以计算、分析每千米边长高程归化改正值。以西南高原地区滇西北某市为例,详细阐述了高原地区地方坐标系的最佳中央子午线和抵偿高程面的选取与地方椭球的建立,通过重点精化区域的控制点予以实现高原地区地方坐标系的建立并对其精度进行分析、验证。
Through the analysis of the influence of topographical terrain and complex landform of the plateau areas in southwest China and that of the establishment of the local coordinate system based on CGCS 2000, the paper uses the ALOS World 3D-30 m DSM data to obtain the local terrain and landform, which can calculate and analyze the correction value of the elevation of each kilometer. Taking as an example a city in the northwest Yunnan in the plateau areas of southwest China, the paper discusses on the selection of the best central meridian, the compensation elevation surface and the establishment of the local ellipsoid of the local coordinate system for the plateau. Through the control points of the key refinement areas, the establishment of the local coordinate system for the plateau is realized, and the analysis and verification of its accuracy are discussed in the paper.
