Calculate new Lat/Lon from initial Lat/Lon plus Cartesian X,Y
Geographic Information SystemsHow do you convert XY coordinates to latitude and longitude? Calculate latitude and longitude using the formula: latitude = asin (z/R) and longitude = atan2 (y,x). In this formula, we have the values of x, y, z and R from step 2. Asin is arc sin, which is a mathematical function, and atan2 is a
