新疆维吾尔自治区斜轴等面积方位投影的研究

A STUDY OF OBLIQUE AZIMUTHAL EQUALAREA PROJECTION OF XINJIANG UYGUR AUTONOMOUS REGION

在本文中，通过研究已经出版发行的《新疆维吾尔自治区小比例尺地图投影》的各种变形特点及其存在的精度问题，并设计出一种精度较高，适合于新疆实际情况的投影——斜轴等面积方位投影．经过严格计算，得出本投影的数据，在此基础上系统地分析它的长度变形，角度变形，优点和缺点等问题，以供给制图生产部门使用或参考．

In the paper we design an oblique azimuthal equal area projection wich possesses a fairly high precision and is suited to xinjiang′s actual situation by studying the various deformed characteristice and the existent problems of precision about the published book smali scale map projection of Xinjiang Uygur Autonomous Region .By a strict calculation we obtained the data of the projection.On the basis of data we study systematically its linear deformations,angular deformations,merits and demerits in order to procide the reference and use to drafting manufacture departments.
