كيف تجد ارتفاع المطار؟

Could you elaborate on the process of determining the elevation of an aerodrome? What specific tools or methods are typically employed in this task? Is it a manual process involving measuring devices or is there an automated system that utilizes advanced technology such as satellite imagery? Additionally, are there any standard procedures or regulations that must be followed to ensure the accuracy of the elevation data? I'm particularly interested in understanding the steps involved in this process and how it affects the safety and efficiency of aircraft operations at the aerodrome.
