Let's take a look at the map projection used by Google Maps. Google Maps,Virtual EarthMap projection used by network geography is often calledWeb MercatorOrSpherical MercatorThe main difference between it and conventional mocato projection is thatSimulate the Earth as a sphere rather than an elliptical body. For more information about why projection is required, see liongg'sWhy map projection Why is it a Circular Sphere instead of an

Central Earth space (Cartesian) coordinate system-defined as the origin O and the earth center coincidence, the Z axis points to the earth's Arctic, the X axis points to the intersection of the Greenwich Meridian and the Earth's equator, the Y axis perpendicular to the XOZ plane constitute the right hand coordinate system. The Cartesian coordinate system of the central Earth space is a type of coordinate system, which is used to describe the position of any point in measurement. Earth-centric co

press the left mouse button to drag the control point for the first time, two control handles will appear on both sides of the control point. If you drag the mouse freely, the control handles will always take the control point as the symmetric point. When you release the mouse and adjust any one, the other will be locked. After adjusting the image, click the mouse again on the control point, and the adjusted control point is restored to the form when no adjustment is made.6. After adjusting the

Level and OID 2. measurement and calculation datum-rotating elliptical Due to the uneven distribution of mass inside the Earth, irregular changes may occur in the direction of the vertical line. As a result, the geoid becomes a complex surface and can

Now, if we want to replace the rectangular element nodes in the original gefpractice example with an elliptical shape, what changes do we need?
