Reprojector

Reprojects feature coordinates from one coordinate system to another.

Parameters

Coordinate Systems

光栅参数

动态坐标系

If the destination coordinate system is specified as "_AZMEA_" or "_AZMED_", each input feature is reprojected to either an equal area or equal distance projection appropriate for that feature, respectively. In general, this causes a new coordinate system to be defined for each input feature.

每个功能都记住它具有的特定相同距离或等于区域坐标系,并且可以安全地重新恢复正常(非动态)坐标系。亚搏在线

As an example:

  1. 存在表示LL-WGS84(普通LAT / LONG)的地球上的点的输入特征。
  2. The point is reprojected to _AZMED_ via a Reprojector with source LL-WGS84 and destination _AZMED_.
  3. The x and y coordinates of the point are extracted into x1, y1.
  4. 设置x2 = x1 + 1000,y2 = y1。
  5. Add a vertex to the point to make the line (x1,y1) -> (x2,y2).
  6. 通过具有源_azmed_和目标LL-WGS84的reprojector恢复回LL-WGS84。

笔记:请注意,源是ignoredhere. We just chose _AZMED_ to help remember what is going on. Sometimes people prefer to set the source and destination both to LL-WGS84.

  1. Now we have changed our point into a line extending 1 km east of the original point, in lat/long.

Dynamic coordinate systems have the following limitation:

•不考虑Z,所以,在椭圆体高度为0米的几何形状中最好保存区域或距离。

Usage Notes

  • This transformer works with both raster and vector data.
  • 该变压器不受光栅频段和调色板选择的影响。

编辑变换器参数

使用一组菜单选项,可以通过引用工作区中的其他元素来分配变压器参数。一些变压器也可提供更高级的功能,例如高级编辑器和算术编辑器。要访问这些选项的菜单,请单击除适用的参数旁边。有关更多信息,请参阅变压器参数菜单选项.
