coordinate geometry

The spatial attribute is a coordinate geometry , or vector-based representation of the shape of the feature.

而空间数据则为空间对象的几何坐标或向量表示.

Although there is a common core in the content of geometry, it is more thin and weak, dealing with the most basic knowledge of plane geometry and the simple application of coordinate.

几何内容虽存在一个公共的核心部分，但非常单薄，它几乎只涉及平面几何的最基础的知识和坐标的简单应用。

First research on the coordinate transformation, and design the tagging method and realizing measurement and automatic tagging of two-dimensional geometry size.

先对其坐标的转换，研究与设计了其标注的方法，实现图像的二维几何尺寸的检测与自动标注。

The approach is to solve z-axis coordinate according to the sensed x-axis and y-axis coordinate data, as well as the spherical geometry relationship analysis, the orientation matrix describing the spherical motor motion can be given and solved based on the screw theory.

这种方法是通过球面的几何关系，由检测到的x和y坐标方向的位置数据计算出z坐标方向的数据，并根据旋量理论建立球电机运动的旋转矩阵和计算出旋转矩阵的旋转角度。

After the coordinate transformation, the discrete velocity Boltzmann equation is solved directly in computational domain to preserve the geometry of body.

直接从离散的速武汉理工大学博士学位论文度Boltzmann出发，物理域离散为保持物体几何外形的贴体曲线网格，然后运用坐标变换，将定解问题变换到计算域中求解。
