1.
By Mercator projection,the geographical coordinates of the ship can be transformed to plane rectangular coordinate,then to the screen coordinate.
通过墨卡托投影,将船舶所处位置地理坐标转换平面坐标,再由平面坐标转换为屏幕坐标,同时将海图按Inmarsat系统作用区域进行划分,推导出每块区域边缘曲线公式,从而可以判断出该船所在的洋区以及与卫星之间的距离,以选择对应卫星进行通信。
2.
In hydrographic sweeping survey,considering that the surveyed route in design project description is a longer route which is composed of two geodetic coordinates,methods of Mercator projection,UTM(Universal Transverse Mercator) projection and Gauss-Kruger projection were adopted to eliminate the direction deviation of sweeping survey,and conform to the conventional way of sweeping survey as well.
在海道扫测工作中,考虑到设计任务书中的扫测航路是由两点大地坐标组成的较长路线,利用墨卡托投影和UTM投影及高斯-克吕格投影方式既能消除扫测航向的偏差,又能符合常规扫测方法。
3.
In order to solve the problem of chart projection transformation among all projections in shiphandling simulator,using the theory of power series spreading out and the method of trigonometric power series calculating back, a direct and reverse solving algorithm models of meridian arc length, and Gauss projection and Mercator projection transforming algorithm are introduced in this paper.
为了解决船舶操纵模拟器中不同投影方式海图的投影变换问题 ,应用幂级数展开理论和三角级数回求方法 ,给出了子午线弧长、等量纬度的直接正反解算法模型及高斯投影与墨卡托投影的相互转化算法 。
补充资料：墨卡托(1512-1594)
荷兰地图学家。第一个设计了将地球表面描绘在平面上的投影方法，即墨卡托投影，使航海者能运用直线导航，不需要转换罗盘方向。编制的《墨卡托地图集》代表了16世纪西方地图的成就。
