![]() Unfortunately, while many other Languages have arctan functions that have "numerator" and "denominator" inputs to handle the case of zero denominators. If the numerator is positive, then the arctan value is pi/2, while if it is negative, the arctan value is -pi/2. ![]() Note that LabVIEW's arctan function needs to be supplemented with a "guard" for a zero denominator. ![]() Enter the sample code for the ConvertDegree custom function described above into the module sheet. Latitude = arctan (Z / sqrt(sqr(X) + sqr(Y)) Start Excel and press ALT+F11 to start the Visual Basic editor. Convert latitude longitude coordinates, address or place on the map to Proj4js is. Longitude = arctan (Y/X) (note that the arctan is defined even if X = 0) Upload coordinates from a UTM table in excel and view in Google Maps. Furthermore, as long as all of X, Y, and Z are not all zero, these equations can easily be inverted: Prerequisite: To convert LatLong to UTM coordinate system, you need to have LatLong data in Decimal degree and save it in CSV file format as shown below. Note your equations, given R, Latitude and Longitude, any values of these quantities will give finite values for X, Y, and Z. ![]() The equations you've cited are the relationships that allow you to convert between Cartesian coordinates (X, Y, Z) and Spherical Polar Coordinates (Radius, Latitude, and Longitude, usually expressed with the Greek characters rho, theta, and phi).
