The standards for geodetic leveling vary depending on the accuracy and precision required by the survey. The NGS website offers many resources for geodetic leveling requirements to meet the United States Standards. I have pasted the URL below. Different areas will have different standards, however, the adjustments and equipment required will be similar. There will be 7 different adjustments you must understand; Orthometric, Rod Scale, Rod Temperature, Level Collimation, Refraction, Astronomic and Magnetic. These adjustments will dictate the process you use to complete the field work. You should be able to find a power point presentation on the website below explaining most of the aspects of geodetic leveling. If you find you have a specific question later please post again!
