conformal latitude

To improve the precision and unify the algorithm,an arithmetic for forward and inverse solution of rhumb line problem based on Mercator projection was presented,and the meridian arc length and isometric latitude were derived by applying lagrange theory and the computer algebra system.

为提高精度、统一算法,应用拉格朗日级数理论和计算机代数系统,推导了经线弧长和等量纬度的计算公式,提出基于墨卡托投影的恒向线主题正反算法。

The expansions of conformal latitude in map projection are studied in this paper.

对地图投影学中经常遇到的等量纬度正反解展开式进行了新的研究。

The Expansions of rectifying latitude,conformal latitude and authalic latitude in mathematical cartography is researched in the paper.

对数学制图学中经常遇到的等距离纬度、等量纬度和等面积纬度展开式进行新的研究。

The input conditions of classification includes equivalent latitude,wide swath imag.

研究区选取在大兴安岭高纬度多年冻土地区呼中自然保护区,应用等效纬度、ASAR雷达图象和坡位分级分别代表影响多年冻土的热量、水分和地形条件,利用ERDAS软件对呼中自然保护区高纬度多年冻土分布信息进行提取,结果表明考虑热量、水分和地形条件确定的多年冻土分布土的精度为86。
