Advantages and disadvantages of barometric leveling?

Barometric leveling is advantageous due to its speed and ability to cover large distances quickly, making it useful for preliminary surveys and remote areas where traditional methods are impractical. However, its accuracy can be affected by atmospheric conditions, such as temperature and pressure variations, which may lead to errors in elevation measurements. Additionally, it requires calibration against a known reference point, which can complicate the process. Overall, while barometric leveling is efficient, its reliance on environmental factors can limit its precision.
