How to get the z coordinate of XY?
If you have an arbitrary cloud of (X, Y, Z) points and you want to interpolate the z-coordinate of some (x, y) point, you have a number of different options. The simplest is probably to just use scipy.interpolate.interp2d to get the z-value:
How to convert a horizontal coordinate to a height?

Can a vector exist independently of a coordinate system?
Vectors are mathematical objects which exist independently of any coordinate system. Introducing a coordinate system for the purpose of analysis, one could choose, for example, a certain Cartesian coordinate system with base vectors ei and origin o, Fig.
How to convert coordinates to state plane coordinates?
Tools are available to convert NAD83 or NAD27 geodetic positions (latitude and longitude) to State Plane Coordinates (SPC), or vice versa. NCAT incorporates many different coordinate conversion and datum transformation software programs that previously functioned independently.
How are Loran coordinates converted to lat / long coordinates?
Observers use the tool in order to convert LORAN coordinates that they receive from captains into Lat/Long coordinates. Data Debriefers use this tool to convert LORAN coordinates to Lat/Long. Alternative location for the application. lorans have to be entered in order from lowest to highest for each set.
Why is the function g not differentiable at x = 0?
Function g below is not differentiable at x = 0 because there is no tangent to the graph at x = 0. (try to draw a tangent at x=0!) Function h below is not differentiable at x = 0 because there is a jump in the value of the function and also the function is not defined therefore not continuous at x = 0.
When to use sine and cosine in a coordinate transformation?
If, in the alternative definition, θ is chosen to run from −90° to +90°, in opposite direction of the earlier definition, it can be found uniquely from an arcsine, but beware of an arccotangent. In this case in all formulas below all arguments in θ should have sine and cosine exchanged, and as derivative also a plus and minus exchanged.
